Ceraunus Blue

More Butterfly Information Blue Butterflies Butterfly Pictures

The Ceraunus Blue (Hemiargus ceraunus) is the sole representative of the Hemiargus genus in the United States.

It's a fairly common southern species, found wherever, legumes, the larval host plant, grow. Its small size makes it easy to miss in the field.

The top of the wings are a solid blue color with a slight dark spot on the botttom of the hindwings.

The underside of the wings, shown above, may or may not have an orange border around the black spots on the hindwing.
