Common Name: Cecropia moth, Robin moth

Scientific Name: Hyalophora cecropia

Season: One generation a year in New England, with adults flying late May into June, and caterpillars from June into the fall.

Food: Many different woody plants in the Northeast: alder, ash, basswood, birch, cherry, dogwood, elm, hawthorn, maple, oak, poplar, wax myrtle, and willow.

Ecology: One of the largest moths in the US, with a very large caterpillar to boot. Unfortunately, this species of moth is in decline, due to a parasitic fly that was initially released to handle gypsy moths, as well as loss of native host plants. Although caterpillars appear to have spikes on their body, they do not sting. Caterpillars will move to the base of host plants and form silken bag cocoons, where they will overwinter.

The Cecropia moth, largest moth in the eastern U.S., made a surprise appearance on Fishers Island July 3, 2018. Dianne Crary was out for a morning walk and spotted the stunning moth on the needles of a yew shrub on Lucinda Herrick’s property.

Adam Mitchell, University of Delaware PhD candidate has encountered Cecropia caterpillars on the Island, but not the adults. “This moth is a female, so she was probably laying eggs for the next generation nearby,” Mr. Mitchell said. “They feed on a lot of different plants, but cherry, birch and sugar maple will likely be the host plants on Fishers.

“Unfortunately, this species of moth is in decline, due to a parasitic fly that was initially released to handle gypsy moths. They also suffer from the loss of native host plants.

“Although caterpillars appear to have spikes on their body, they do not sting. Caterpillars will move to the base of host plants and form silken bag cocoons, where they will overwinter.”
