Azure damselfly (Coenagrion puella)

Length 30-35mm. The male abdomen is a variegated deep, bright blue and black, the thorax is streaked blue on sides. The female abdomen is mostly black above, with thin greenish rings. Large numbers patrol just above and among pond-side herbage.

Common blue damselfly (Enallagma cynathigerum)

Length 30-34mm. The male is powder blue, the female usually green-marked, but some are blue- or yellow-patterned. It’s a stronger flier than other damsels, venturing further out over open water.

Large red damselfly (Pyrrhosoma nymphula)

Length 34-38mm. Black, with broad red stripes on the thorax and a tail heavily marked with bright red (less so in female). Preferring well vegetated areas, it appears from mid-April and is often the first damsel (or dragonfly) on the wing.

Banded demoiselle (Calopteryx splendens)

Length 43-48mm. A beautiful, dark, iridescent green (female) or blue (male), each of the wings of the male carry a large, inky-blue blotch. With a butterfly-like flutter, it settles on herbage along slow-moving, silt-bottomed streams.

Common darter (Sympetrum striolatum)

Length 35-40mm. The thorax is brown, but the tail a bright scarlet (male) or straw yellow (female). With a slim abdomen, it is active and restless, and will sun itself on bare ground or perch on water-side vegetation rather than erect stems.

Broad-bodied chaser (Libellula depressa)

Illustration of a broad bodied chaser, with its powder-blue, short and broad abdomen

Length 40-45mm. Has a distinctive broad, flat tail – the male powder or Wedgwood blue and flecked with yellow, the female (and immature males) all brown. The yellow marks can make them look hornet-like. Likes to perch frequently.

Emperor (Anax imperator)

Length 75-80mm. Our largest and brightest dragonfly, its thorax is apple green and the tail a blue (male) or green (female) with black linear marks. A powerful flier, it surveys open water from several metres up rather than skimming the surface.

Brown hawker (Aeshna grandis)

Length 70-76mm. Has a milk chocolate abdomen that is almost imperceptibly flecked with yellow (female) or blue (male). Wings are a smoky brown, visible even many metres away as it traverses a reed bed, lake, canal or slow-moving river. Glides, then flutters.

Southern hawker (Aeshna cyanea)

Illustration of a souther hawker, with a black, green and blue abdomen

Length 65-77mm. Black, strongly marked with green and turquoise (female) or blue (male). Has a wedge mark on first tail segment and broad marks on the front of the thorax. A powerful inquisitive flyer, it will buzz a person as if to inspect them.
