The Common Blue (Enallagma cyathigerum)

The Common Blue Damselfly

The Common Blue is abundant throughout most of the UK, as its name suggests. It can be located on a wide range of stillwaters and the slacker areas of slow flowing rivers and canals.

It is the brightest of the blue damselflies and can be identified from other species by the wide blue stripes on the top of its back and the "dot " shaped marking, just behind the wing bases.

The female appears some what blacker in appearance, owing to the larger and longer abdominal markings & can be seen in blue and green forms.

It can be seen on the wing from early May and occasionally late April right through to late August and even early September.
