Pear slug (Pear sawfly)

Insect

Pear slug (Pear sawfly)

Caliroa cerasi (L.)

Hymenoptera: Tenthredinidae

Distribution: Most fruit-growing states and provinces in eastern North America.


The adult looks similar to a small, black-bodied wasp with the ventral side and legs yellow in color. The larva is small, fleshy, dark green to orange, slug-like, and slime-covered, with the front part of the body enlarged (A). As the pear slug grows in size, it becomes somewhat lighter in color, until it is nearly orange-yellow when full grown (B).
