Pear Sawfly (Pear Slug)

Orchards and gardens on host plants like pear, cherry, and hawthorn trees.

Larvae feed on the leaf tissue (mesophyll) between the veins, leaving the skeletonized leaf behind.

Larvae are often covered in a dark, slimy secretion that makes them resemble small slugs. They typically feed on the upper surface of leaves.

Can cause significant defoliation in ornamental and fruit trees, reducing tree vigor and fruit production. They do not pose a direct risk to humans.
