Anisodactylus porosus is a ground beetle in the family Carabidae, part of the tribe Anisodactylini. The genus Anisodactylus includes species known for granivory—feeding on weed seeds—though specific dietary habits of A. porosus have not been separately documented. It occurs in North America, with records from Canada and the United States. Like other members of its genus, it likely inhabits open, disturbed habitats including agricultural fields and gardens.
Scolopostethus
dirt-colored seed bugs
Scolopostethus is a genus of dirt-colored seed bugs comprising more than 30 described species in the family Rhyparochromidae. Species occupy diverse habitats including ruderal areas, weedy lawns, and ant-associated environments. Some species are myrmecophilous, living near ant nests through chemical defense strategies rather than chemical mimicry. The genus has a Palearctic origin with at least one species, S. affinis, recently established in North America.
