Dusky Birch Sawfly
A medium-sized sawfly with an orange abdomen and black head and thorax. Larvae are yellowish-green with dark spots and feed in rows along the edges of birch leaves.
Did You Know?
The larvae feed in a distinctive edge-to-edge pattern, consuming the leaf blade while leaving the midrib intact like a fishbone.
