Bug of the Week: Sneaky Geometrid Moths

It’s too windy today for a fresh photograph, so let’s look at some moths from the archives.

Some moths are good at camouflage.

As you might imagine, the brown moth above would be completely hidden on the bark of a tree.

Other moths don’t appear to use camouflage.

For example this white-winged large lace-border, Scopula limboundata stands out against the dark green background. It is not blending in.

So, is this moth in disguise?

It sits completely still on dark green vegetation with its wings outstretched. Nothing could be more obvious.

Maybe from this direction the coloration makes more sense. Doesn’t it look like a dead leaf?

The patterns do look a bit like leaf veins. What do you think?

These moths belong to the family Geometridae. Their caterpillars can also be masters of disguise.

“Nothing to see here,” the caterpillar says.

Answer to Twig or Insect Post: Geometrid Caterpillar

Was it a twig or insect sitting on a black raspberry plant in our last Bug of the Week post?


It was hard to tell, but this is a photograph of a looper or inchworm caterpillar (family Geometridae). In fact, because so many caterpillars in this family resemble twigs they are commonly called “stick caterpillars.”


When I approached, the caterpillar was moving in the typical looping fashion across the plant. I startled it when I stopped to take its photograph, and the caterpillar rose up and straightened. It held this position for as long as I watched it, which was several minutes.

If I hadn’t seen the caterpillar moving prior to taking this stance, I probably wouldn’t have even noticed it.

This caterpillar will eventually turn into a moth, making it an appropriate way to announce:

National Moth Week is coming up in the end of next month, July 23-31, 2016.
