Hoplocampa pectoralis

The abdomen is yellow above. The stigma of the fore wing is darker near the base than the apex. The wings are subhyaline with the costa, subcosta and base of the stigma are greyish brown with the apex of the stigma and the rest of the venation being yellowish. In the female, the head is mainly black with two orange spots, but in the male the darkness may be reduced to the post-occipital area. Females also have the lower portion of the mesopleura black. The hind tibia is as long as the hind tarsus. Males can be determined by the penis valves.

Hoplocampa pectoralis larvae feed in the developing fruits of hawthorns.
