Sun Pug Fun

Pugs, the caterpillar of geometrid moths in the genus Eupethicia, favor composite flowers and especially seem to prefer rudbeckia and sunflowers. You can see very tiny ones as soon as the disk flowers start to produce pollen, and watch them grow and perform their various bodily contortions across the sunny flower faces.

This one on a fading sunflower is doing the stick imitation, in which the caterpillar extends and stiffens its body I suppose in a effort to look like a stick.
