Dorytomus ictor


3.8 to 4.5 mm.

Identification difficulty

Mating occurs early in the season when pairs may be found on trunks or nearby fences etc. but they are nocturnal and so possibly under-recorded at this time, during the day they remain among bark or in wood crevices and are inactive.

When to see it

Adults overwinter, sometimes gregariously, and are active very early in the year, from January although they will often be active during mild winter spells, and they persist into April or May.
