Nova Scotia to South Carolina, west to Missouri and Nebraska, north to Saskatchewan
adults fly from October to December, overwinter, and fly again from February to May; occasionally active in mid-winter on warm days
larvae in spring and early summer
Larvae feed mostly on leaves of black cherry, and some other deciduous trees such as plum, pear, and crabapple. Caterpillars need to eat young leaves; they will starve if only eating older leaves. Late instar larvae may also feed on the fruit of the host plant.
Life Cycle
one generation per year; overwinters as an adult; eggs are laid in spring and hatch when host trees are beginning to leaf
The moths can be attracted with sugar bait.
