Yellow-winged Darter

The Yellow-winged Darter (Sympetrum flaveolum) is a rare vagrant from the continent, although it bred briefly in the 1940's at Alderfen . It occasionally invades in large numbers - the last being in 2006. It is unclear why this species doesn't breed here, on the continent it is found as far North as Finland so temperature seems unlikely to be a limiting factor.
