"Satyrium titus," Wikipedia, the free encyclopedia. Satyrium titus, the coral hairstreak, is a North American butterfly in the family Lycaenidae. 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. The coral hairstreak is frequently seen visiting butterfly weed, but also uses New Jersey tea, dogbane and sulphur flower as nectar plants.
