Euura stichi

The head has a black spot between the ocelli and the depressed parts of the metanotum in front of the cenchri are black. In the female the abdomen is entirely yellowish at most with basal tergites in the middle with small black dots. The male has light brown antennae with the underside yellowish. According to Muche, the degree of the black colouration on continental specimens is variable and the mesonotum and top of the abdomen can be extensively black.

Euura stichi larvae feed on grey willow.
