The larvae, being of a gregarious habit, feed on Ipomoea species (morning glory, sweet potato, bindweed, moonflower, etc.) with a voracious appetite, which can have a potentially dangerous impact on crops This one was about 15 mm (0.59 in) in length, which is (from what I've read) pretty much as big as they get.
Subtropical mountainous area, hot & humid, thick brush and trees.
