Ametastegia perla
A genus of slender elongate sawflies. In Ametastegia perla the abdomen is marked with black above and yellow below. In the female the tergites are black with a median row of triangular yellow patches that broaden apically. In the male the yellow extends across the entire apical margin of each tergite so that the black is broken into a series of lateral spots.
Larvae feed on redshank, osiers and poplars.
