The Common Winter Damselfly (Sympecma fusca) is distinct from other damselflies because it does not have a metallic green colour that is common in the Lestidae family of slender damselflies. It is also pale brown - not blue or red. The adult male often changes his eye colour from brown to blue in winter, but the female lacks the blue colour. It is found in much of central and southern Europe.
