Picromerus
Picromerus is a genus of predatory shield bugs in the family Pentatomidae. Species in this genus are predatory throughout their life cycle, feeding primarily on lepidopteran larvae and other soft-bodied insects. Several species, particularly P. bidens and P. lewisi, have been studied extensively for their potential as biological control agents against agricultural and forest pests. The genus exhibits specialized adaptations for predation, including well-developed olfactory systems for locating prey and host plants.
