The pear slug or cherry slug is the larva of the sawfly, Caliroa cerasi, a nearly worldwide pest.
 They are not slugs but are a kind of sawfly of the family Tenthredinidae.
 The pear slug is an important pest that eats leaves of cherry, pear, and plum trees, leaving behind a skeleton of veins.

 When the larvae are fully grown, they drop off the tree on the ground and pupate underground.
 The adult sawfly emerges from the pupal case and climbs from the soil to mate and lays eggs on the leaves of the host plant, completing the lifecycle.
