Morning-glory Prominent / Checkered-fringe Prominent / False Unicorn Caterpillar

Schizura ipomoeae

Description:

A leaf-mimic caterpillar. Looks like the dead edge of a leaf. Has fine setae (hairs) on segments (that were not visible until I processed the image). It has two red pegs on the 1st abdominal segment and smaller pegs on the 4th, 5th,, and 8th abdominal segments.

Habitat:

Distributed throughout the United States and southern Canada feed on the leaves of various woody plants, including Beech (Fagus), Birch (Betula), Elm (Ulnus), Maple (Acer), Morning-glories (Ipomoea), Oak (Quercus), and Rose (Rosa) species Can be found from May to October.

Notes:

This caterpillar was approximately 1.5 inches long and was found on an ornamental witchhazel (Hamamelis sp.). I found another smaller caterpillar – approximately 1 inch long – on this plant. Schizura unicornis has a very similar caterpillar. The head stripes and humped A5 (fifth abdominal segment) of this species are listed as distinctive in Wagner (3) p. 314. S. unicornis – see http://bugguide.net/node/view/454269, also has a white V-shape over A6 and A7 which S. ipomoeae lacks.
