Microdiprion pallipes (Fallén, 1808)

Microdiprion pallipes

Mainly black with pale legs. Abdomen shining. The scutellum is longer than broad and acutely angled in front. Claws without an inner tooth.

Larvae feed on pines, especially Scots pine. Small trees up to 1.5m are preferred. Larvae feed in groups on young needles initially, then moving on to old needles. Microdiprion pallipes can be bivoltine in years with favourable weather and the two generations can overlap.
