Euura monticola

In the female the head is black with the labrum and clypeus always yellow and usually with an upper eye spot. In the male the whole head is orange with a more or less large frontal postocellar black stain. The thorax is black with the posterior corners of the pronotum and tegulae yellow. The abdomen is predominantly orange, though the male has the basal tergite black and the following tergites with black transverse marks, and the female from the third tergite either with small central spots or completely orange-red. The legs are yellow often with black on the base of the coxae, the lateral faces of the femora, and the apices of the tibia and tarsi.

Euura monticola larvae are undescribed.
