Today we hit the jackpot with leaf-miners while we were taking a hike with the dog. We found a whole bunch of leaves with signs of leaf-miners…how exciting!
(Original post HERE and the OHC Challenge HERE)
We were amazed at how crazy the path is on some of the leaves. Curls and swirls and then along the edges, there seems to be no rhyme or reason.
The creation of a thousand forests is in one acorn.
Ralph Waldo Emerson
We also were fascinated with the furry, fuzzy tops on these acorns. I like how they grow like twins on the branches of the oak tree.
I found a few on the ground along with some moss for a cute little acorn photo.
Just wanted to update our study with our latest finds.
We found quite a bit of leaf damage on the oaks in our backyard…nothing that really looked like leaf-miners though. We looked carefully which is part of what this challenge (More Nature Study #2 Leaf-Miners and Rollers) was all about.Taking time to really look and see the leaves opens up lots of interesting thoughts and ideas. Who caused the damage? Were they nibbled by insects or something else like the birds that frequent our yard?
The preparation work from the Handbook of Nature Study really helped us with this challenge.
We went around to the garden side of the yard and started to look at the shrubs there and we think we found several leaves that had been rolled up by insects. This one looks close to what we were looking for so we are going to assume it is our subject for this challenge. Amazing that I never noticed this leaf-rolling in our own backyard until now! What else am I missing?
Now in the front yard we have a different kind of oak and we were able to see clearly some damage done by some insect…perhaps a leaf-miner. We couldn’t find any leaves that had insects working on them currently but these looked promising enough to bring a few inside to look at under the magnifying lens.
Here is one image (through the magnifying lens) that was super pretty, almost looked like stained glass.When you hold the leaf up to the light as suggested in the Handbook of Nature Study it is even more beautiful. My husband was wondering what I was looking at and I had to share with him too. He was fascinated by our topic and since he spends lots of time outdoors as part of his job, he is going to keep an eye out for some more leaves to look at with the hand lens.
Another image up-close at what we think may be what we were looking for this week.
So there you have it…our leaf-miner and leaf-roller study in our own yard. Amazing that we could find it right under out noses. I think that is the lesson I learned from reading the entries to the Blog Carnival for this challenge from different families…..total amazement that they could even find this subject so close to home.
If you haven’t taken the time to give this challenge a try yet, there is still plenty of time to do so. Make it an investigation after reading the information in the Handbook of Nature Study. Take your magnifying glass with you outdoors to look at the suggested plants (see Lesson 77 in the HNS).
We also observed some oak galls which are covered in Lesson 79 in the Handbook of Nature Study. These are interesting to observe as well and surprising to most that they are actually signs of an insect.
My Prairie Sunflowers are now blooming…took all summer but they are now showing their very cheery faces. I am sort of glad they waited so long to bloom because all the other sunflowers are done and in the compost.
How would you like a great link to a some coloring book pages? Celebrate Wildflowers
Apparently, flowers have a “biological clock”. I have been fascinated with this idea all summer and I think it makes for an interesting read: How To Make A Flower Clock. On that note, my Four O’Clocks are just about ready to bloom. I have been nursing them along all summer and I think they finally are getting some flower buds…need to watch for the bloom time.
We still have an abundance of insects in our late summer/early autumn garden. In fact, they are even more active from what I have observed. These bees were loving the trumpet vines…sharing at times with the hummingbirds.

Our zinnias are such great performers and are relatively maintenance free except for cutting the flowers and enjoying them in a vase on your kitchen table. 🙂
We have enjoyed our container dahlias this year…seeds from Rene’s Garden. I found this paper craft for dahlias…so very pretty and fun. Then again, I may just pull out the watercolors later and made an entry in my journal.
We are working on cleaning up the garden … lots of trimming, raking, pruning, harvesting, picking, and composting going on here. Garden update next week.
Here comes the second challenge in the new series of Outdoor Hour Challenges! I will be posting one new challenge each Friday and you are welcome to jump in and work through the challenges as you have time.
Inside Preparation Work:
1.Read in the Handbook of Nature Study pages 329-334 (Lessons 77 and 78). Pay special attention to the “Leading Thoughts” and the “Methods” sections in each lesson. These will give you hints and ideas for searching for Leaf-miners and Leaf-rollers.
2. Optional YouTube Video: Watch a leaf roller HERE. One short one showing it up close HERE.
3. Preview this YouTube video of a leaf miner at work: The Good, The Bad, the Ugly…Larva. Awesome! Watch it full screen if you dare.
Hints: Look on sumac, basswood, and witch hazel for leaf-rollers. We have found leaf-rollers on our crepe myrtle and coneflowers. For leaf-miners, look on nasturtium, columbine, lamb’s quarters, dock, and burdock. You may also try pine needles for yellow tips. We have found leaf-miners on oaks.
Outdoor Hour Time:
1. Go outside with the intention of looking for and observing some insects. Keep in mind the images of the leaf-miner and the leaf-roller. Look for signs of these kinds of insects on the leaves in your garden or in your neighborhood. There are many varieties of each kind of insect so you may wish to consult your field guide before you head out.
2. If you don’t find any insects to observe, take a few minutes of your Outdoor Hour time to examine various leaves with a hand-lens. Look for anything that has damaged the leaves and describe what it looks like. Many things can damage leaves besides insects.
Follow-Up Activity:
1. Insects are hard to identify but the point of this challenge is mainly to look for Leaf-miners and Leaf-rollers and how they use leaves during their life-cycle. If you can see the larva or the insect itself, you may have a good chance at identifying it. On the other hand, you may just need to talk about the behavior of this kind of insect and give the opportunity to sketch the leaf and your observations. You can use the accompanying notebook page for convenience (ebook users only).
2. Advanced Follow-Up: Read this link for more information on leaf rolling insects: Leaf Rollers on Ornamental and Fruit Trees ( UC Davis). Complete the Upper Level notebook page with your research (ebook users only).
This challenge is part of the More Nature Study – Autumn series. All of the challenges are gathered into one ebook with notebooking pages (regular and for advanced students) and additional resources. You can gain access to this ebook by purchasing an Ultimate Naturalist membership here on the Handbook of Nature Study. See the Join Uspage by clicking the link at the top of the website for more information about what comes with your Ultimate membership.
It feels like fall and the front yard is starting to change and take on the colors of autumn. The leaves are starting to drop from the Tulip tree, blanketing the ground with a riot of yellows, oranges, and browns.
Time for a front yard update! I can hardly believe this is the same yard that we planted last fall and saw come alive last spring. You can see my July Update post for several images of the garden. We have been able to cut our watering down to twice a week and I anticipate even less next summer once the plants are all established. It is amazing the color and variety you get even within drought resistance plants. I love this yard so much more than the old ordinary lawn we replaced.
Note: We live in a dry place. Normal summers mean NO rain at all and this was a dry summer. We have had somewhat cooler than normal temperatures up until the last ten days. The heat turned on and I have been closely watching the yard for signs that I needed to water a bit but the only thing I pulled the hose out for was to fill up the birdbath.
One of my favorite aspects of this garden is the many textures and the movement that you notice when you watch it from the window. The grasses sway in the slightest breezes.
Here is a close-up of the pink fountain grass. It is so very delicate and feathery.
One of our goals in plant choices was to have the yard become a habitat for living things….like these butterflies.
We also wanted fragrances and with the lavender, sage, and butterfly bushes all in bloom we have a yard that smells inviting to humans and other creatures.
If you look closely at the left bloom, there are two skipper butterflies stopping by to enjoy the flower this morning. The plantings also encourage the birds to visit and the hummingbirds can be seen daily in and out of this garden.
Everything about this yard inspires me to be creative….the delicate pinks of the butterfly bush, the lavender of the sage, the crimson of the crepe myrtle. I just want to snap as many photos as I can so on a cold winter afternoon I can pull them out and paint some in my journal to cheer me up, reminders of warmer days.
One last butterfly on the sage….this plant didn’t look very healthy at the beginning of the season but it loved the heat and sunshine. It made an amazing comeback. (I like the shadow of the sage on the rock below the butterfly…just like lace.)
Another great update showing the progress in our frontyard remodel. It has been a year since we underwent the big change and I have no regrets.
Jami’s Tuesday Garden Party meme is open from Tuesday to Thursday so there is still time for you to jump in and participate!
Up until last year I would not have know what this flower was called but we focused on it during the Summer Series of challenges last year. There is something wonderful about being able to name a flower or tree or bird, making it a part of your world. You can own it.
We took two hikes in Yosemite while camping this week, one new and one familiar. We drove up Tioga Road towards Tuolumne Meadows and stopped at Yosemite Creek. We hiked down the creek about two miles, enjoying the sound of water running over the rocks. This creek eventually filters down to fill Yosemite Falls…the iconic waterfall that so many come to see from all over the world. This time of year it is not much more than a small stream coming over the top but come next spring it will be a torrent.
Here is another view of Yosemite Creek which right now is lined with wildflowers. We stopped and took a break sitting on rocks as we took in the sights and sounds of the wilderness. We only saw two other people hiking on this trail the whole afternoon we were out there. It is an amazing experience to have this spot of the wild all to yourself.
Well, unless you count the insects. These Ranger’s buttons had a variety of insects enjoying the summer sunshine. We couldn’t name these critters but it was interesting to watch them do their work.
This trail was also home to quite a few trees that showed signs of bear scratchings. The bark on this cedar tree was roughed up by bear’s claws.
I started calling these “bear curls” since they were where the bear had pulled the tree bark down making it twist into curls. Interesting? I think so.
We also spotted this HUGE fungus on the side of another tree…really high up. Can you believe the size of it? Amazing to see!
The second hike we took was to Taft Point which is off Glacier Point Road. It is a favorite hike for the boys since there are lots of boulders to climb and the view once you get to the point is incredible….and high.
Here is a shot of the boys at the railing which is right at the edge of the cliffs….sorry no photos of the view to the valley or over across the valley to Yosemite Falls since my camera batteries were both dead. I broke my camera when we were at the Grand Tetons and I now have it duct taped shut but the battery door opens up and somehow the battery drains down very fast. I am in the market for a snew point and shoot.
The hike was highlighted by a slithering Rubber boa crossing the trail right in front of us. He was about 24-30 inches long and not in a very big hurry. We were able to get a really good look at him. Funny thing is we were just talking about how we never see snakes while in Yosemite and then we saw this one….weird.
Okay, so if you are not into snakes, how about a pretty wildflower? This is Monkshoodand I have only seen in two places at Yosemite so I was happy to catch it in bloom. The yellow in the background is Arrowleaf groundsel.
We spent some time in the Valley walking the paths under the trees and I was on the look out for some thistles in preparation for the up-coming thistle challenge. I was pleased to find both milkweed and thistles growing right together along the trail. The thistles are in a variety of stages of life…some blooming, some going to seeds, and some getting very dry.
Guess who came along for us to observe? Mr. Dragonfly was enjoying the Bull thistles right along with us. So very pretty to look at!
Here is another insect coming to feast on the thistles…this one was very buzzy and I took a quick photo and then got out of his way.
The Showy milkweed is all producing large seed pods and we found this milkweed beetle crawling on one of the pods. These pods are amazing to see and touch…just like velvet.
So this is my new wildflower for the trip. We identified this lovely lavender flower as Sierra lessingia. We read in our field guide that Mary Curry (of Curry Village) called it Summer Lavender and I would agree with her that because it grows in such large patches in the flat spots along roads and in the valley, it looks like clouds of lavender. I love learning something new and now I can name that pretty flower that grows so profusely this time of year in the Valley.
So there you have our hikes and wildflowers, bears and beetles, dragonflies and snakes. So many things to enjoy and learn about when you get the opportunity to get to know a place….
Pond study is always a great summertime activity and that is one reason I chose ponds as the theme of the August Newsletter challenges. We spend one day a week at Grandpa’s helping him with yard work and he has a small pond that is spring-fed and we enjoy investigating it when we visit.
Dragonfly in our backyard earlier this summer
We started off our dragonfly study with the dragonflies that visit our backyard everyday during the summer months….some looking like little hummingbirds and others looking like helicopters. We sometimes even have a swarm of dragonflies all at once in our yard and then they disappear.
For the August Newsletter challenge to observe some dragonflies, we visited Grandpa’s pond with the intention of expanding our dragonfly study. He has blue damselflies which are so pretty and before we knew any better, we called them dragonflies. There are some simple differences between dragonflies and damselflies.
Dragonflies land with their wings out and damselflies land with their wings in
Damselflies have wing pairs that match and dragonflies the wing pairs are dissimilar
Dragonfly eyes touch or nearly touch and damselflies have clearly separated eyes
We read in the Handbook of Nature Study about the dragonfly and made some notes on our nature notebook pages. Mr. B drew both the Bluet damselfly and the Red skimmer dragonfly and they will go side by side in his nature journal.
For more information on using the OHC to learn more about dragonflies, you can see OHC #28.
I cannot resist sharing the prettiest dragonfly I ever saw and was able to get a good image for my nature journal. This one we saw when we were in Atlanta, GA a number of years ago. I think he is magnificent!
Dragonfly Link to Lapbook Pieces on HomeschoolShare: Dragonfly Animal Study. If you have little ones you could print out the “What is the difference?”, “Dragonfly Design”, and “Dragonfly Diagram” pieces and include those in your nature journal. What could be easier?
I look forward to seeing some of your pond studies or any other nature studies you have been cooking up this month. Make sure to submit your entries to the Outdoor Hour Challenge Blog Carnival. The link is at the top of my blog and on my sidebar.
We have been working on our July Newsletter Nighttime Critter Challenge all month. I wanted to post a little of what we are observing and learning to give you an idea of how you can pick a few things from your area to study in the evening hours. I will update our list after the end of the month with any new finds.
Our most predominant nighttime critters of interest are the Brown bats that come every single night to fly in our backyard. I wrote about them back in May as part of mammal study. For the July newsletter challenge for Nighttime Critters, I decided to share a few of our other nighttime visitors of interest. This study was sort of on-going because when the weather is hot, we tend to drag sleeping bags out to the back deck to sleep in the cool night air. We all lay awake and listen and watch as the nighttime settles in around us.
Shooting stars, satellites zipping across the sky, the moon, the swaying trees in the breeze, and the night sounds all entertain us as we wait for sleep to come.
Fill In The Circle and Fill In With Color Example – Poor owl sketch…he has such a crooked beak.
One of the things that we have discovered sleeping outside on hot summer nights is that we have quite a few great horned owls in our neighborhood. We can hear them calling back and forth right after the sun goes down and then again at around 5 AM. Here is a link to AllAboutBirds.org and if you click the sound button, you will hear the two types of sounds we hear from our owls: Great Horned Owls. We have yet to actually see them but they are out there…no doubt about it.
We also are serenaded by crickets when the temperatures get just right. It is amazing how you don’t hear any crickets and then all of a sudden it is as if someone turned on a cricket soundtrack and they all chirp at the same time. The lesson in the Handbook of Nature Study gives a great illustration showing the parts of the cricket and an excellent explanation of how he “sings”. (Lesson 82)
“The wing covers are much shorter than the abdomen and beneath them are vestiges of wings, which are never used. The male has larger wing covers than the female, and they are veined in a peculiar scroll pattern. This veining seems to be a framework for the purpose of making a sounding board of the wing membrane, by stretching it out as a drumhead is stretched.” Handbook of Nature Study.
Turn in your copy of the Handbook of Nature Study to read much more in the lesson explaining this interesting creature.There is such a simple explanation of the mechanics of the crickets chirping that it is perfect for sharing with younger children. The crickets and the frogs compete in our neighborhood for the winner of the “background” noise. It seems as if one or the other is singing their little hearts out.
We smell skunks quite a few nights a week. Sleeping outside we hear rustling in the garden and I think it is the skunk. I know they dig around the base of the birdfeeder outside our window but over the years I have decided that if he leaves me alone, I will leave him alone. Here is another entry where I talk about our nighttime visitors.
List from the July Newsletter. I cut it out and taped it inside my nature journal.
One last nighttime critter we have had around the neighborhood is the raccoon. Our neighbor has been sharing how they keep forgetting to bring in the dog’s food dish at night and the raccoon has decided that it makes a easy snack taken just outside their patio door. We have had our share of raccoons in the yard over the years but we haven’t seen any lately. Here is an entry sharing one raccoon experience: Raccoon Visitor.
Well that gives you a taste of what we have around here in the evenings. I just thought of something else I need to put on my list….moths.
I look forward to reading about your nighttime critters. Don’t forget to post your entry and then submit it to the Outdoor Hour Challenge Blog Carnival before 7/30/11 for a chance in the July Newsletter giveaway!
Since we just studied and observed our honeybees, we decided to learn more about another common backyard insect that we see all the time in our butterfly garden….the Western tiger swallowtail. There are some amazing images on this webpage. There is also quite a bit of information on Enchanted Learning.
We often see swallowtails on our butterfly bushes.
This rather large butterfly is a frequent visitor to our backyard habitat. One afternoon this past week I watched as two swallowtails dipped and swirled around the garden. They are so pretty but they don’t stay put very long at all.
We pulled out the Handbook of Nature Study and read the section on Black swallowtail butterflies to get sort of an overview of this insect. (Lesson 70) Here is a little excerpt:
“This graceful butterfly is a very good friend to the flowers, being a most efficient pollen-carrier. It haunts the gardens and sips nectar from all the blossom cups held out for its refreshment; and it is found throughout almost all parts of the United States. The grace of its appearance is much enhanced by the “swallowtails,” two projections from the hind margins of the hind wings.” Handbook of Nature Study, page 301
We got out our insect field guide and found out some more interesting facts:
Its caterpillars feed on alder, poplar, willow.
Habitat: Mixed and deciduous forests, open ares, even in urban areas.
Wingspan 3 1/2″ to 4 3/8″
Yellow wings, single “tail”
This Saturday, July 16th, is the day that the Great Sunflower Project is requesting that we observe our bees. Read more about how you can participate HERE. I look forward to hearing about your bees as part of the July Newsletter challenge. You can also observe your sunflowers at the same time!
Our choice for the Garden Critter study this month is the honeybee. We have been building a bee, butterfly, and bird habitat in our yard this year and it seemed fitting that we take a few minutes to read in the Handbook of Nature Study (Lesson 99) about this welcome guest to our garden.
We have planted many bee attractive plants and every day, rain or shine, they come to visit. Their favorite spot in the yard is the center square filled with lavender. If you sit close by, you can hear the buzzing of wings and you can watch their activity among the flowers.
Water for the Bees – Lavender and Baby Lemon Queen Sunflowers
We read recently online that bees need water as part of their habitat. We found a shallow pie pan, filled it with an assortment of local rocks we had on hand, and then filled it with water. The rain has kept it filled but now that the weather is looking like it will remain dry, I will just replenish the water when I water the garden. Here is a really informative article about Planting a Bee Garden.
This is what we are aiming for…image from two summers ago in our sunflowers. Can you believe that pollen?
We will be taking part in the Great Sunflower Project later in the summer. I highly recommend this nature activity which is fun and simple to do as a family. Click below for more information.
Don’t forget to post and then submit your June Newsletter nature studies to the Outdoor Hour Challenge Blog Carnival. Here is THE LINK. If you need to find the link quickly, it is at the top of my blog in a couple of places for easy access.
Jami’s Tuesday Garden Party meme is open from Tuesday to Thursday so there is still time for you to jump in and participate!
