Where There is a Web: Fall Webworm

Yesterday we went looking for more insects in our backyard. We saw some more daddy longlegs...actually lots of daddy longlegs. We saw a tiny little spider on the marigolds but he would not hold still for a photo. I took this pretty photo of my marigold anyway. Look closely and you can see the pollen.

Then we found this wonderful web on the crepe myrtle bush. I looked high and low but did not see what made the web. After doing some research, I discovered this to be the web of a Fall Webworm or
Hyphantria cunea. In the larval stage, they create these great webs where they feed entirely inside the web. The adult is a moth that has white wings and has grayish-brown spotting on the forewings.




From page 295 of the Handbook of Nature Study:
"While the young pupils should not be drilled in insect anatomy as if they were embryo zoologists, yet it is necessary for the teacher who would teach intelligently to know something of the life stories, habits, and structure of the common insects."

I am finding this to be essential to our study of insects. I need to know a little information about each thing we find and weave it into our study. It doesn't take much time to open the Handbook of Nature Study, skim the table of contents, and turn to the page for more information. I am finding that just having read the introductory pages to the section on insects has provided more than enough information to get started.

From page 295:
"From the eggs, larvae (singular larva) issue. These larvae may be caterpillars, or the creatures commonly called worms, or perhaps maggots or grubs. The larval stage is devoted to feeding and to growth."

Now I have a little vocabulary to use with the boys when we see caterpillars. I can point out that these are insects in their larval stage and their main objective in life is to eat. We can find this stage annoying when they are eating the leaves of our garden plants but we can understand a little more about it.

We observed a bee dancing in the pollen of a cosmos flower. He was digging into the pollen and practically rolling in it. Here is a slightly blurry photo of him...try to get a bee to sit still. You can see the pollen on his body.


My favorite photo of the day is this one. It is a close-up of my son's dahlia flower. There had been a little insect on it that I was trying to capture but he was too quick.


Well, that is what we saw and observed yesterday. I am finding the more we look, the more we realize that we have to see.
