Description
 
 

Coral hairstreak is a small to medium-sized butterfly with a wingspan of to 1¼.

The upperside of both wings is dark brown. However, this butterfly perches with wings closed and is rarely seen from above.

The underside of both wings is light brownish-gray. The forewing has a faint submarginal row of black and/or orange spots, a postmedian band of small black spots ringed with white, and a short, broken, ill-defined, medial stripe. The hindwing is not tailed. It has a postmedian band of small black spots ringed with white, and a prominent marginal row of eight orange spots. The orange spots are small and well separated. There is no blue eyespot near the outer angle.

The eyes are black.

The antennae are black-and-white striped with a orange-tipped club.

The caterpillar is wide, somewhat flattened, and short, no more than 1 long. The head is small, black, and shiny. It is retracted into the thorax except when feeding. The thorax and abdomen are densely covered with short downy hairs. The thorax is yellowish-green to green with an ill-defined red patch in the middle of the upper (dorsal) surface. The abdomen is mostly yellowish-green to green. Abdominal segments 1, 7, and 8 have an ill-defined, red, dorsal patch. Abdominal segments 9 and 10 are all or mostly red. There is a thin, dark green dorsal stripe extending from abdominal segments 2 to 7. Mature caterpillars are found from May to June.

Biology
 
 

Season

 
 

One brood: late June to early August

 
     
 

Behavior

 
 

Caterpillars hide in leaf litter or at the base of a host plant during the day. They emerge at night to feed on leaves and fruits.

 
     
 

Life Cycle

 
 

The female lays eggs singly, usually on a new twig of a host plant, sometimes in leaf litter where new growth is expected. The eggs overwinter and hatch in the spring. The larva molts 4 times before pupating.

 
     
 

Larva Hosts

 
 

American plum (Prunus americana), black cherry (Prunus serotina var. serotina), chokecherry (Prunus virginiana var. virginiana), juneberry (Amelanchier spp.), and other trees and shrubs in the Rosaceae (rose) family.

 
     
 

Adult Food

 
 

Flower nectar, especially butterfly weed (Asclepias tuberosa ssp. interior) and spreading dogbane (Apocynum androsaemifolium), but also common milkweed (Asclepias syriaca), swamp milkweed (Asclepias incarnata ssp. incarnata), clover (Trifolium spp.), sweet clover (Melilotus spp.), white meadowsweet (Spiraea alba), strawberry (Fragaria spp.), blackberry (Rubus spp.), black-eyed Susan (Rudbeckia hirta), and spotted knapweed (Centaurea stoebe ssp. micranthos).
