Ascra bifida is a species of stink bug in the family Pentatomidae, commonly known for its distinctive odor and its role in the environment. Stink bugs are a group of insects that are notorious for their ability to produce a foul-smelling chemical defense when threatened. These insects are primarily herbivores, feeding on the sap of plants, which can sometimes make them agricultural pests.
