This damselfly is metallic green, becoming bronze as it ages. It has relatively broad, pale ante-humeral stripes on the thorax, and a pale back to the head. At rest, the Southern Emerald spreads its wings at a wide angle to the body. The pterostigma is bi-coloured. Males become pruinescent only on abdominal segment S10.
Still, shallow, waters; will tolerate brackish conditions. Seems to favour dune slacks and other coastal sites in our area, though has occurred inland.
Status & Distribution
Migrant from Northern Europe, possibly the Netherlands where it has increased recently. First observed in July 2002 in Norfolk. Also in the Channel Islands since 1995. Now occurs almost annually, and has been proven (2018) to breed.
