|scientific name Bembidion lapponicum |
On barren sandy (sometimes clay-mixed) banks and shores of rivers and lakes.
Member of the inaequale group (subgenus Bracteon). Similar to B. carinula but prothorax without latero-basal carina. Color duller, due to generally stronger microsculpture, usually greenish or brassy (never coppery), legs darker than in normal carinula, with femora entirely black or red only at base or, rarely, entirely piceous red. Third elytral interval almost constantly more suddenly widened before anterior silver spot which is at least twice as broad as 4th interval; the dark color of mirrors often more extended upon adjoining intervals than in carinula.
Overwinters in the adult stage.
Both larvae and adults are predatory.
This species if found in northwestern United States, and western Canada. In Alberta this species is known only from the southern region.
