Tenthredo omissa

One of the smaller yellow and black species on Tenthredo. The flagellae of the antenna are entirely black as are the tegulae. The hind tarsus and apex of hind tibia is reddish-brown in both sexes. Yellow bands on the tergites do not broaden laterally. Formerly associated with the fens of Norfolk, Suffolk, Lincs and Cambs but now more widespread where similar habitats exist.

Tenthredo omissa larvae feed on plantains and possibly other herbaceous plants.
