Bug of the Week: Boreus borealis


Boreus brumalis can be found on sunny winter afternoons, when air temperatures approach zero degrees Celsius. You can find them in large numbers scuttling along the snow’s surface. Females have reduced wings that are barely visible. In contrast, the male has The elongate, hardened wings that are used for grasping the female in order to mate. Their mating position looks a little like the male is giving the female a piggyback.

For a nice review of the interesting lifecycle of this insect, check out this 1979 paper by JD Shorthouse.
