Notiophilus biguttatus
spotted big-eyed beetle, Common springtail stalker
Notiophilus biguttatus is a predatory ground beetle in the family Carabidae, native to the Palearctic and introduced to North America. It is a specialized predator of springtails (Collembola), particularly Orchesella cincta, and exhibits distinctive mass aerial migration behavior during July in some populations. The species has been extensively studied for its density-dependent predation, food-limited growth, and reproductive costs including accelerated ageing.
