The parasitoid samurai wasp (Trissolcus japonicus, a female shown here emerging from a host egg) is a natural enemy of the brown marmorated stink bug (Halyomorpha halys). When H. halys arrived in North America in the late 1990s, a team of insect taxonomists sprung into action to seek potential biological control agents. Without such taxonomic capacity, the work to respond to invasive species would be much more difficult. (Image originally published in Buffington et al 2018, American Entomologist)
