New Jersey Butterflies

Coral Hairstreak

Satyrium titus

Identification: Very small—about the size of a thumbnail, but just a bit larger than most of NJ's other Satyrium hairstreaks. Like most hairstreaks, almost never seen with wings open. Below: Gray-brown with a row of bright orange spots near edge of HW. Only hairstreak in NJ that does not have tails.

NJ Status and Distribution: Resident. Uncommon but widespread. Data show that Coral Hairstreaks are still found in most counties but the general sense among active field observers is that the species is declining.

Comments: Coral Hairstreaks absolutely love Butterfly Weed. The bright orange blossoms of this plant match the color of the hindwing spots of the butterfly. Also shows fondness for dogbane. If you have Black Cherry trees in your yard or neighborhood, and plant Butterfly Weed in your garden, you just might attract this lovely butterfly.
