Populicerus obsoletus

This is apparently a very variable species, as numerous collections taken across Canada show. Teneral males and about two-thirds of females are pale unmarked green (similar to pallidus ); about one-quarter of females have fuscous lateral angles on the scutellum and often an indefinite brown clouding along the commissure (as the type of obsoletus ); the remainder of the females and most mature males have extensive fuscous or brown clouding over the clavi and adjacent parts of the corium (as the type of vagus ). Occasional individuals may have the green colour replaced with pink, or with only the thorax, or only the abdomen pink, the rest of the body being green. Preserved specimens of pink individuals eventually turn ochreous (like the type of duzeei ). - Hamilton, 1980 Hamilton (1980) rendered Idiocerus duzeei a jr. syn. of obsoletus . Hamilton (1985) later resurrected duzeei as a distinct taxon. Here on BugGuide, Hamilton referenced Populicerus obsoletus as a subspecies of Populicerus pallidus . It is unclear where this concept originated.
