Hello! We live in Iowa and came across this bug yesterday along a bike trail. Could you tell me what it is? Thank you!!
This is a Pandora Sphinx Caterpillar. Judging by the number of adult moth photos we received this year, we expect your photo to the the first of numerous requests for the caterpillar identification this season. Grape is one of the food plants for the larva and your specimen appears to be be feeding on grape.
