Euura incompleta
A lowland species mostly black and green in colour that can be swept from meadows. Apart from the ground colour being green instead of yellow, they are indistinuishable, both morphologically and genetically, from Euura myosotidis and may therefore be the same species (M. Prous, pers comms). In the female the abdomen is broadly pale green at the sides and apical margin of each tergite but otherwise black medially. The head is black with a yellowish-white clypeus and a yellowish spot at the top of the inner orbits, though this is often indistinct. Often in the female, and normally in the male, the posterior orbits are yellow-brown as are the pronotal angles, the tegulae. Sometimes the mesopleura are streaked with yellow. The legs are light greenish-yellow.
