When to seeJune to September
AboutThe Emerald damselfly is a medium-sized damselfly that lives among lush vegetation around the edges of ponds, lakes, ditches and canals. When perched, Emerald damselflies have a habit of holding their wings half-open, rather than closed along the length of their body like other damselflies. 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 identifyMale 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 similar Scarce emerald damselfly is a much rarer species that is confined to the south and east of the country.
