About

The emerald damselfly is a medium-sized damselfly which lives amongst lush vegetation around the edge of ponds and lakes, ditches and canals. Perched emerald damselflies can be distinguished from the other damselflies by their habit of holding their wings half-open, rather than closed along the length of their body. The last species of damselfly to emerge in the UK each year, they are on the wing from the end of June to September.

How to identify

Male emerald damselflies are metallic green, with pale powder-blue eyes. The tip of the abdomen is also blue, as is the thorax. Females are metallic green with pale beige stripes on the thorax. The scarce emerald damselfly is a much rarer species and looks very similar. It is confined to the south and east of the country.
