Agabus punctulatus is a species of predaceous diving beetle in the family Dytiscidae.[1][2][3] It is native to upper North America.[4]
Description
[edit]Found in fresh grassland ponds, this beetle ranges from 5.5 millimetres to 6.4mm in size. [4] It can be identified by this small size as well as its black brown to dark red dorsal color. A greenish sheen has been observed on its thorax, covering pale elytra. The species displays sexual dimorphism, with males having claws on their hindlegs and a ventral tooth just below the apex on these claws. This claw with a tooth allows for simplified identification of the species in the field.
Distribution and Habitat
[edit]Agabus punctulatus can be found mostly in Canada and Alaska, but its habitat extends down to the contiguous United States in a two-pronged fork pattern.[4] In the west, it reaches as far south as New Mexico and California, but in the east, it only extends to New Jersey.
