Aeshna mixta Latreille, 1805
Migrant Hawker

Type locality: environs of Paris, France

Diagnosis

It is usually identified by its size, relatively dull colours and the diagnostic yellow ‘nail’ mark at the abdomen base. Distinctly smaller than most Aeshna, except A. affinis, which see for a comparison. The upperside S2, with its central T- or nail-shaped yellow marking, is most notable in mature males, where it contrasts with the blue abdominal spotting; females and fresh male have yellowish spots. The antehumeral stripes are reduced to a short yellow stripe in both sexes. Together with A. affinis, differs from most Aeshna by having two (not three) columns of cells in the anal loop, three (not two) cells in the anal triangle and seven to nine (not more) cross-veins between the node and pterostigma. Unlike A. affinis, the male upper appendages are without a tooth on the underside near the base, and the female appendages are longer than S9-10 combined. [Adapted from Dijkstra & Lewington 2006]
