Euura poecilonota
Males are very rare. Very variable in colour and size but the pale colour is green in life fading to yellow. The head is light yellow with black antennae and a black frontal ocellar spot, which can occupy the whole occipital area. The thorax in the male is black. The posterior corners of the pronotum, tegulae and more or less the mesopleura are pale. The female thorax is pale with black stripes on the mesonotum, and black marks on the scutellum and the scutellar appendage. The abdomen is pale below and mostly completely black above in the male, and in the female with a more or less broad middle stripe. The legs are pale with the apices of the tibiae and the tarsi black.
