Description
 
 

Rosy maple moth is a common, small, silkworm moth. It occurs in the united States and southern Canada east of the Great Plains. Caterpillars are found feeding on the leaves of hardwood trees, especially red maple, silver maple, and sugar maple, but also boxelder and oak. Adults do not feed.

The adult is 1 (26 mm) in length and has a wingspan of 1¼ to 2316 (32 to 55 mm). It is a medium-sized moth but one of the smallest royal silkworm moths.

On males, the antennae are feather-like, with branches on both sides of the central axis (bipectinate). On females, the antennae are thread-like, unbranched.

The color is highly variable. The thorax is densely covered with long hairs that may be bright yellow, pale yellow, cream-colored, or white. The wings are rosy pink except for a broad median area which can also be bright yellow, pale yellow, cream-colored, or white. Sometimes the subterminal area is the same color as the median area. The legs are always rosy pink. A completely white form, called alba, occurs in Missouri.

The mature larvae, called green-striped mapleworm, is pale bluish-green or whitish-green with seven narrow, dark green stripes. On the second segment of the thorax (T2) there are two long black horns. On the abdomen there is a row of short black spines in the dorsal, subdorsal, and subspiracular areas. The subspiracular spines are the longest. There is often a rosy patch below the breathing pores (spiracles) on the seventh and eighth abdominal segments (A7 and A8). The head is beige to orangish-brown.
