Very bright pink (fuschia), translucent caterpillar with pink strip down back. I thought it was a worm at first because of its movement and the very slick (hairless) exterior, but it was too fast and didn’t inch, but rather, crawled. It looks like a piece of candy! It had some spots, but they look like damage, not like a pattern. The head is clearish-pink and the tail end just has the tiniest little tails sticking out in a V-shape. Almost unnoticeable. I saw this in Spring, TX in October. I have never seen anything like it and I have lived in Houston my whole life.
Your caterpillar looks like the gray hooded owlet caterpillar. It would be good to have a side view besides the top view of the caterpillar to be absolutely sure. Your photo is also much brighter pink than most seen. Many of these caterpillars vary in color…most are green to light pink to pink with the light stripe down the back.
This caterpillar turns into a long slender brown moth that looks like it has a hood over its head.
The caterpillar eats flowers and leaves of plants in the aster family, which is a big family including asters, daisies, sunflowers, dandelions, mums, chicory, zinnias, chamomile, marigolds, etc.
It is not a pest.
This caterpillar is found over most of North America except in the southwestern part of the US.
This caterpillar does not bite nor cause a rash.
