Priacma serrata – Bleach Beetle
Priacma serrata is an enigmatic insect from the conifer forests of western North America and is one of a handful of species belonging to the relictual beetle suborder Archostemata. It is often thought of as a “living fossil”, bearing a strong resemblance to the earliest known beetles that pre-date even the dinosaurs.
Males are attracted to the scent of bleach, presumably because it resembles a female pheromone, and are sometimes collected off air-drying laundry. In spite of its unique evolutionary position, the biology of Priacma has not been adequately studied.
