How to Manage Pests

Pests in Gardens and Landscapes

California pear sawfly—Pristiphora abbreviata

Sawflies are wasps. Although they resemble moth caterpillars, sawfly larvae have more prolegs (one on each body segment) and their bodies taper from the head to the tail end. They are bright green with light brown heads and black eye spots. Larvae can be hard to spot as they position themselves within the holes they make, eating in a circular fashion.

Life cycle

Damage

Sawfly larvae cut circular holes along leaf margins and within leaves during spring. Sometimes the entire leaf is consumed except for the midrib. They do not feed on fruit.

Solutions

Trees can tolerate large numbers of sawflies without suffering much damage.
