Satyrium titus
Satyrium titus, the coral hairstreak, is a North American butterfly in the family Lycaenidae. Description
This tailless hairstreak is brownish gray on the upper side of the wings. The underside of the hindwing has a distinct row of red-orange spots along the outer margin, but lacks the blue spot found in most hairstreaks. Habitat
This butterfly favors brushy places, thickets, overgrown fields, open woodlands, and streamsides. Nectar plants
The coral hairstreak is frequently seen visiting butterfly weed, but also uses New Jersey tea, dogbane and sulphur flower as nectar plants. Host plants
Caterpillars have often been reported on feeding on the fruits of wild plums and cherries (Prunus), and have also been observed on serviceberry (Amelanchier alnifolia) and oaks (Quercus). References
