Caliroa annulipes is a species of insect. Its common name is the oak slug sawfly.

Description

All Caliroa larvae are coated with a translucent mucus membrane, which is seen as slug-like. The larva body color depends largely on the color of the content of their guts.

They have a bivoltine flight period, May and August.

Adults are small, 4-6 mm long, black-bodied, with white markings on the legs. They are short lived.

Range

They are recorded in Britain and Ireland.

Habitat

They are found in habitat where its host trees and shrubs grow, including gardens, parks, and woodlands.

Ecology

Caliroa annulipes is associated with oak, birch, willow, lime, beech, and bilberry species. Larvae feed by grazing the underside (epidermis) of leaves, skeletonizing them, for up to about 3 weeks.

Caliroa annulipes is classified as a species of least concern in Great Britain.

Etymology

"Annulipes" derives from Latin annulus ("ring") + pes ("foot"), i.e. "ringed-footed," referring to the pale ring-like markings on the legs.
