Unlike other damselflies, emerald damselflies all spread their wings at an angle to the body, and willow emeralds follow this pattern. This damselfly is metallic green.

How can people help

The Wildlife Trusts manage many wetland nature reserves for the benefit of all kinds of wildlife, including damselflies. But these precious sites are under threat from development, drainage and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities and be helping local wildlife along the way.
