A cherry slug
or pear slug
is a saw fly larva
with scientific name Caliroa cerasi
. They are not slugs but are a kind of insect of Tenthredinidae
family. The cherry slug is an important pest that eats leaves of cherry, pear, or plum trees, leaving behind a skeleton of veins. The larvae cover themselves in green slime, making themselves unpalatable to predators. When the larvae are fully grown, they drop off the tree on the ground and form a pupa underground. These will then develop into a sawfly that hatches out, mates and lays eggs on the leaves completing the lifecycle.
