Explanation of Names
Atalantycha bilineata (Say 1823)
6-9 mm(1)
Pronotum sometimes mostly black with narrow central and lateral orange yellow margins (1)
larva -- see Papp (1984) (2)
e NA (NS-FL to MN-TX)(3)(4)(5)(1)
hardwood and pine forests(1); adults like the flowers of Red Haw, Viburnum rufidulum(6)
Usually the first cantharid to emerge in the northeast in the spring(1)
Life Cycle
Larvae, perhaps, feed in rotting wood, since there appear to be swarms emerging/and or mating around fallen logs in NC. Mating is prolonged in this species--I have seen it go on for days. The larger female drags the male along, and he seems unable or unwilling to let go. (P. Coin, pers. observation)
