Identification
The forewing is grey and brown, generally lacking any trace of medial lines. Instead forewing veins are somewhat darkened in the median areas with white streaks from the post medial line to the outer fringe, running parallel to the inner margin. Has a very light, almost white border along the forewing costa.
Range
This subspecies occurs in the Northeast, from coastal New England south to Virginia. It is locally abundant in coastal pine-oak barrens, such as Cape Cod, the New Jersey Pine Barrens, and the pine barrens of Long Island, NY.
Habitat
Oak/Pine Barrens
Season
June to August; peak in July
Food
Oak species
Life Cycle
Eggs are laid on bark in fall and hatch in spring. Adults eclose from pupae at soil surface.
See Also
The parent species, Catocala herodias (Herodias Underwing), is very similar, but distinguished by the lack of the very light, almost white border along the forewing costa present in gerhardi.
