The lateral flanges on A2-A5 are characteristic of three common inchworms (see Chlorosea banksaria; the third species, Synchlora aerata, is not illustrated). Coloration in this species varies among light green, yellow, tan, and brown. Depicted here is a caterpillar with colors darker brown, grey, and black. This species is common on many broadleaf trees and shrubs, such as white oak, myrica, ocean spray, bitterbrush, and snowbrush, during March to September.
