Life Cycle


Photo by Brenda Dziedzic

Rosy Maple Moths have 1 brood in the north and 2 to 3 broods in the south each year. The eggs are yellow and laid on the leaves of the host plant.

An egg is between 1/32 and 1/16 inch wide. It takes about 10 to 15 days for the egg to hatch. The development of the caterpillar is visible through the egg.

When the caterpillar hatches, it is about 3/32 inch long.

The young caterpillars feed in groups.

In later instars, they become solitary. The caterpillar is about 2 inches long in the last instar.

The caterpillar burrows into the ground to pupate. It does not spin a cocoon. The last brood overwinters in the ground and emerges the following year.

Adult Food

The adults do not feed because they have no proboscises. For that reason, they have short lifespans.
