Doru (earwig) explained

Doru is a genus of earwigs in the family Forficulidae.^[1]

Description

Doru can be recognised by having yellow elytra with a black suture.^[2]

According to the original description by Malcom Burr, the third and fourth antennal segments are subequal. The elytra are not carinate. The abdomen is subparallel and depressed in shape. The anal segment of the abdomen is transverse, depressed and not sloping. The pygidium is spinous or sharp. In males, the arms of the forceps are slender, removed from the base and not expanded.^[3]

Ecology

In North America, these earwigs can be found on grasses and sedges, usually near water.
