Pine sawflies are pests of pines. They are often confused with moth larvae but the adult of these insects is more like a fly.

The insects overwinter as eggs that hatch out during a two week period in early May. The insects feed for 4 to 6 weeks. The insects pupate in litter beneath the tree or in protected sites on the lower trunk. The adults emerge in early September to late autumn. After mating the females lay eggs in slits in pine needles.

The insects eat the old needles but leave the new shoot alone. The insects feed in colonies and when disturbed will bob up and down.

Controls include Orthene.
