Strangalia luteicornis

One of the ‘Flower Longhorns’ (Lepturinae).  Many in this group have elytra that taper back from the thorax so they look like they have broad shoulders.  (Bugguide)

Larvae feed on decaying wood of some deciduous trees and woody vines.  Adults feed on nectar and pollen from flowers; they may be especially fond of sumac.  (Bugguide)
