Phymatocera aterrima (Klug, 1816)

Phymatocera aterrima

The Solomon's seal sawfly. An entirely black species often seen flying around the host plant. Very similar to Rhadinoceraea micans. In aterrima the antennae are at least three times as long as the width of the head and as long as the whole body. In micans the antennae are about twice as long as the width of the head and about as long as the abdomen.
The larvae feed on Solomon's seal and can be very destructive.
