American Copper Butterfly

Order: Lycaena phlaeas

We first sighted this small, erratic, fast-flying butterfly while on one of our many photo adventures, and noticed that it kept visiting a small patch of weeds. Upon very close inspection — on our hands and knees, with noses almost touching the ground — we found some white dots that we hoped were eggs, and collected the leaves.

At home we had to use a magnifying glass to find out if we were right. They weren’t much bigger than a period on this page, but they sure looked like eggs to us. The weed we identified as sheep sorrel, common in our area. We waited and hoped that the eggs would hatch — and sure enough, they did.

Host plants: Sheep sorrel, mountain sorrel

American Copper Egg


White, with tiny dimples like a golf ball, American Copper eggs are by far the smallest butterfly eggs we’ve ever seen. They’re laid singly.

American Copper Caterpillar


When newly hatched, the caterpillars are light yellow.

After first molt, the caterpillar turns light green, with short fuzzy hairs covering most of its body. It blends in well on the host plant. Eating slowly, it matures in a few weeks, reaching only about a quarter of an inch long. At maturity, the caterpillar stops eating and rests for a while before shedding its skin one last time.

American Copper Chrysalis


The Copper’s small, bean-shaped chrysalis is green at first.



It gradually turns light brown.


After about ten days, the chrysalis becomes transparent.

Two American Coppers


Only the size of a nickel, the little Copper doesn’t stay still for very long. It often chases others of its kind, as if playing tag.

American Copper On Leaf


Because its host plant is very short, the Copper frequents fields and meadows with a lot of low-growing vegetation.

Perched American Copper


The Copper drinks nectar from wildflowers, dandelions, and white clover, among other flowers.
