Red-veined Darter (Sympetrum fonscolombii)
This medium-sized (38-40mm) is a fairly frequent migrant to the UK and can be found at suitable sites along the south coast in reasonable numbers.

Mature males can be identified by the blue underside to the eye and red vein on the fore-wing. In flight they are quick and unpredictable, with short bursts of speed as they navigate around bank-side reeds and rushes.

Females usually oviposit in tandem with the males, choosing emergent stems.

During 2012 and 2015 the New Forest had an influx in late May which went on to breed and produce fair numbers of offspring the following August. Both male and female offspring were present in large numbers and curiously did not reach their mature colours, remaining the bright lemon colour of tenerals.

It is assumed that these tenerals emigrate back to the near continent. There is currently no proof that they have established repeated breeding colonies here, although some sites are reliable from year to year.
