Aeshna mixta

Aeshna mixta Latreille, 1805


Common name: Migrant Hawker

Preferred environment: can be seen at a wide variety of lowland ponds and lakes including natural and artificial sites. The species can tolerate brackish sites.

Flight period: July to the end of October according to location. In Britain recorded from July to the beginning of November end of October with peak in mid August to mid September.

Adult habitat and habits: a non-territorial species often aggregating at feeding and breeding sites. Maturing adults favour woodlands and sheltered areas. Aggregations in excess of 1000 individuals have been reported in southern England. At breeding sites males patrol over the water, again without showing aggressive behaviour. Mating is lengthy, taking place in waterside vegetation.

Oviposition site and behaviour: females oviposit usually alone inserting eggs into marginal plants often above water surface or occasionally in bare mud.

Larval habitat and habits: eggs diapause and hatch in spring. Development is rapid and is completed by mid to late summer.

Emergence behaviour: emergence happens at night on emergent and marginal vegetation plant stems.

Range: southern and central Europe north to the Baltic. Absent from northern half of Britain, Scandinavia and Finland. Also in north Africa, the Middle East across central Asia to Japan.

Determination of adults: adults: species is keyed and diagnostic features including male abdominal appendages are figured in Askew (1988). Mature adults are illustrated in colour in Askew (1988) and Brooks (1997).
