The antennae and legs of the plant wasps are noticeable for the species , as they are partly white in color. The 6th, 7th and 8th antennae are whitish. The femur (thigh) is reddish. The upper part of the tibia (splint) is white, while the lower part and the tarsus (foot) are black.
The mainly gray colored larvae (anal caterpillars) reach a length of 25 mm.
Occurrence
The animals are found all over Europe including the British Isles and are widespread in Central Europe .
Way of life
The adults of Apethymus serotinus fly in late summer and autumn (mid-September to late October). They lay their eggs in the bark of younger branches of oak ( Quercus ), where they hibernate. In spring, the larvae hatch and feed on the newly emerging oak leaves. The larvae go through 6 stages over a period of about a month before they enter a summer diapause in the soil and then pupate. In alluvial forests there can occasionally be mass reproductions and corresponding forest damage.
