Brochymena affinis
rough stink bug, tree stink bug
Brochymena affinis is a native North American stink bug in the family Pentatomidae. Like other members of its genus, it is commonly known as a "rough stink bug" or "tree stink bug" due to its bark-like camouflage. The species overwinters as an adult, typically remaining outdoors under loose bark rather than entering buildings. It produces one generation per year in temperate climates, with development from egg to adult taking an extended period.
Brochymena lineata
rough stink bug
Brochymena lineata is a species of rough stink bug in the family Pentatomidae, native to North America. Like other members of the genus Brochymena, it exhibits cryptic coloration that mimics lichen-mottled bark, providing effective camouflage against tree trunks. The species was described by Ruckes in 1939. As with congeners, it is not considered an agricultural or household pest.
