American Copper

Lycaena phlaeas

The American Copper flies a foot or two off the ground in rather quick sorties from one nectar source or perch to another. Being only an inch in wingspan, the American Copper would seem to be a seldom-observed species, but its colorful coppery wings give away its position.

Weekly sightings for American Copper

Identifying characteristics

The forewing above is orange with black spots and a grayish-black border. The hind wing above is mainly dark gray with an orange border. Below, the front wing is similar to the upper surface but a lighter shade of orange, while the hind wing below is a much lighter shade of gray, with black dots throughout and a zigzag submarginal line.

Usually 3-4 broods per year, with the first occurring in late May or early June, and then lasting until October in some years
