Camouflaged!

Are you impressed with my picture of this small branch off an ash tree?

It even includes a caterpillar.

This is the other end of the stick with another caterpillar on it.

The head end of the caterpillar resembles a bent stick.

The caterpillar shows better here with its hairs raised from the broken twig.

It’s a caterpillar of a dot-lined white moth (Artace cribraria) which grows to two inches long. They feed mostly at night and rest on the bark during the day. Their host plants include cherry and oak trees, roses and other woody plants. They overwinter in the egg.

Years ago my Mother and I were having a picnic at Bell Smith Springs in the Shawnee National Forest (in southern Illinois). The caterpillar dot-lined white moth above joined us at the picnic table. It didn’t blend in with the table as well as it thought it did.

black eyes

It didn’t like her attention and “eyes” opened on the back of its thorax in an attempt to scare us.

Then to get its point across, it raised into a cobra position and swayed back and forth from one side to the other.

It refused to be intimidated!

Its fake head resembled that of a cobra’s head.

Double-Ringed Pennant

 A double-ringed pennant (Celithemis verna) didn’t mind my attention this morning and posed for a few pictures. This is a male; the females have a yellowish thorax and a little yellow on base of  their abdomen.

Neighboring Spiders

My neglecting the water garden created a lot of habitat.

Changing the camera angle showed a  second opening.

A young garden spider spun its web higher where it would catch more flying insects.

Wheel Bug Nymph

I kept thinking “wheel bug” while taking pictures of this bug. Wheel bugs have a prominent semicircular crest on their thorax.

Apparently, this one isn’t an adult yet. It was feeding on a soldier beetle.

I took this picture in early July of 2009.

Wheel bugs have one generation a year and overwinter as eggs. One website stated that the wheel bug’s bite is usually worse than a bee sting. Both nymphs and adults should be avoided.
