Essex Red Data List comment
Formerly known from only I site, now more widespread, but still vulnerable?
This is a medium sized, dark coloured hawker dragonfly with a noticeably hairy thorax. It breeds in mesotrophic, unpolluted lakes, ponds, mature sand and gravel pits, ditches and fens where there is an abundance of tall emergent vegetation such as club-rush, reed, bulrush and great fen sedge. It is most abundant in coastal grazing levels of Somerset, Sussex, Kent and Norfolk and also occurs in the East Anglian and Anglesey Fens, the Cheshire Meres and the coastal wetlands of south Wales. In Essex it was formerly known from only one site, but has now become more widespread. References
