If you were asked to identify this insect structure, what would you suggest?
Tent caterpillar nest? Perhaps fall webworm?
Let's take a look at the larvae inside.
The larvae aren't hairy or fuzzy like some of the caterpillars that make silk nests.
If you look closely, you'll see these larvae have too many prolegs to be moth caterpillars (for a discussion of prolegs, try this post).
The insects in the photos are webspinning sawfly larvae. Sawflies are relatives of bees, wasps, and ants, yet their larvae look and act like butterfly caterpillars.
Have you ever spotted sawfly larvae and thought they were caterpillars?
Are you a science educator or homeschooling parent? If so, you know how hard it can be to find quality materials to kick start or supplement your science lessons.
Today we are featuring a resource you might find helpful. The Exploring Nature Educational Resource website has over 5,000 pages of top-notch illustrated science materials for use online, to download and print, or to display on a Smartboard. Subscriptions are $25/year (at the time this was posted) for individuals or families, and school rates are also available.
Illustrated science lessons are so important for young visual learners and can help any style of learner grasp concepts more quickly. Author and illustrator Sheri Amsel created the materials specifically for the site, which means they are consistent in style and format. They are not recycled from other sites on the internet.
Think of the website as a series of online textbooks on different science topics that go with you wherever you need them. They aren't just science lessons, either. There is a test bank to use and information about Next Generation science standards to help with your own curriculum planning. The how-to-draw instructions and coloring pages would be useful for art lessons and projects, as well.
Interested? Check the links below to examine some of the topics for free (Thanks to Sheri Amsel for providing the links). If you choose, stop back and let us know what you think in the comments.

Insects can interfere with exercise.
For example, these light-colored objects on the dark bark of a mesquite caught my eye and I had to run home and grab my camera.
Do you recognize it?
Here, look closer.
It's the exoskeleton shed by a cicada turning from a nymph into an adult. Can you see the covering where the eyes were? How about the large front legs used for digging?
The bulbous area in front of the eyes is the covering for the part of the mouth that pumps fluids from plants. The flap-like structure on the side of the body is the wing bud that develops into the wing of the adult.
Have you ever found a cicada nymph exoskeleton? Where did you find it? Did you look at it closely?
