Tenthredo campestris · pjūklelis

Tenthredo campestris is widespread in the northern Palaearctic from southern Scandinavia to the Mediterranean.

Females reach body lengths of 12-14 mm and are considerably larger then the males who only reach a length of 9 - 12 mm. The bodies are bright red and black. The head, thorax, and eyes are black. The antennae are yellowish and comprise 7 or 9 segments. The abdomen is black, shiny, and has a large reddish-yellow or yellow stripe in the middle of its upper surface. It is longer and wider in the females than in the males. The wings are milky-transparent. Their venation is clearly observable. The forewings lack the subcosta. The upper section of the legs is reddish-brown to yellowish-red. Towards the feet there is a yellowish tinge.

The larvae are yellowish after hatching and resemble caterpillars. They have 8 small pairs of legs attached to their abdomens. Their antennae have 4 - 5 segments. When disturbed, the larvae curl into a "S" shape and resemble small snakes. En masse these larvae can cause major damage to shrubs and trees.
