01 Banded Demoiselle (Calopteryx splendens)

Identification - Banded and Beautiful Demoiselle are the only damselfly with coloured wings in the UK. Male Banded Demoiselle have a large dark-blue/black band across the centre of the blue veined wings and a deep blue body colour with metallic green iridescence and similar eye colour. Females have a metallic green body colour, sometimes bronze-green, terminating in a bronze tip. Wings are iridescent pale-amber/green or bronze without the dark centre colour band. Immature males are similar in body colour to mature males but with brownish eyes and the wing band is brown green. Immature females have very pale yellow wings and brown eyes.

Status - There were few records of this species until 2006 but are now frequently seen. Banded Demoiselle are less common than the ‘other blue’ damselfly on the Reserve. Active period generally from May through August.

02 Azure Damselfly (Coenagrion puella)

Identification - Males are predominately blue coloured with blue eyes with thin black rings on the body and have a characteristic ‘U’ shaped black mark on the second segment. Female adults have similar head and thorax markings as males but predominately greenish with thick black separation rings although a pale blue form occurs rather than the vivid blue of the males. They also lack the black ‘U’ shape mark on the second segment. Immatures differ from the adults by both having pale-brown base body colours, more pinkish in the males, with brown eyes which change into the adult colours with maturity.

Status - This distinctive damselfly is common throughout the reserve with an active flight period generally from April through August.

03 Common Blue Damselfly (Enallagma cyathigerum)

Identification - This species has been found to be common on all four beds since recording began in 1986. Similar looking to the Azure Damselfly but in general appears to have more blue than black colouration which is reversed in the Azure Damselfly. It also has a wider blue antehumeral stripe on the thorax than the Azure Damselfly and only one black line below this blue antehumeral stripe. Females can be blue coloured as the male or a dull green/grey colour and can be difficult to separate without attention to finer detail.

Status - Relatively common across the Reserve with an active period is from April through September.

04 Red-eyed Damselfly (Erythromma najas)

Identification The male has a dark grey abdomen with a blue tip and deep red eyes. The thorax is bronze/black in both sexes but the female has small yellowish antehumral lines as well. Mature females have dark black-grey abdomens, from top, greenish underneath, with greenish lines separating the segments.

Status First recorded in 1986 and repeated in 1998 but was probably overlooked until 2006. It is now regularly seen around the Reserve with an active period from April through September.

05 Blue-tailed Damselfly (Ischnura elegans)

Identification All forms and sexes are predominately dark bodied. Mature males, always have a bright blue spot at the tail, blue stripes on the thorax and blue eyes. Immature males emerge with greenish stripes on the thorax with gradually change to blue. Females are more variable in colour with mature forms ranging from blue like the males to green thorax + brown tail spot and pale brown thorax + blue tail spot. Immature females can have a violet or pinkish thorax both with blue tail spots.

Status Blue-tailed Damselflies are probably the most common species on the Reserve with an active flight period generally from April through September.

11 Migrant Hawker (Aeshna mixta)

Identification This is one of the latest flying dragonflies and the only Hawker likely to be sighted into November. The male appears dark in flight with paired blue spots along the abdomen and blue eyes. Females are browner with the same paired markings but these are often smaller and yellowish occasionally blue and the eyes are brown. Up close, a small golf-tee shaped diagnostic light mark is clearly visible on the top of the second abdomen segment in both sexes.

Status This species, first recorded in 1998 now vies with the Brown Hawker for the most common ‘Hawker’ species on the Reserve and is active from July through October.

12 Emperor Dragonfly (Anax imperator)

Identification Our largest dragonfly, the male has a bright blue abdomen with a clear black central strip running the full length of the body. The female has a greenish not blue body but similarly marked as the male. Both have a green thorax and green to blue eyes. When first emerged both sexes appear paler green with brown markings before their colours age.

Status First recorded in 2001 has been regularly seen on all our water bodies. The irregular records on the Reserve are probably due to under reporting. Flight period is from April to September.

13 Downy Emerald (Cordulia aenea)

Identification Metallic green with a coppery sheen and, as all the ‘emeralds’, noticeable light green eyes. The male is distinguished from the female by a ‘waisted’ abdomen and ‘club’ shaped body. Both sexes have a downy thorax from were the name is derived.

Status A single adult in 1990 is the only Woolston record to date. The principle flight period is from April through July.

18 Yellow-winged Darter (Sympetrum flaveolum)

Identification Not resident in the UK but is known to migrate here in some years in numbers. Breeding populations occur after these eruptions but fade out after a few years. Males become orange red with maturity and with a red-brown thorax. The females have an ochre yellow abdomen with black marking along the lower sides. The basal areas of the wings especially the inner rear wings are noticeably coloured pale yellow-orange.

Status A continental vagrant, a single male was recorded in 2006 on No1 Bed. The active period for migrants is July through September.

19 Red-veined Darter (Sympetrum fonscolombii)

Identification The males are bright red and females yellow-brown. The eyes are brown above and blue-grey below and the bases of the hind wings are yellowish. The pterostigma (dark spot on the leading edge of the wings) is yellow to orange strongly outlined in black. Males become a deep red with maturity with red veins on the wings, particularly on the leading edges, and the thorax are red-brown. Females have a ochre-yellow abdomen with two black lines along each side. The wing veins are yellow at the leading edge and base. Immature males are coloured as the females but have only a single line along each side of the abdomen.

Status A single male was recorded in May 1989 after a large influx into the UK of this continental species. A dragonfly of central and southern Europe which in some years migrates north, increasingly since the 1990’s, as far as northern England. The principle flight period is May to November.

20 Ruddy darter (Sympetrum sanguineum)

Identification Male abdomens become blood-red (not orange-red as in Common Darter) with maturity with red-brown thorax and they exhibit a very noticeable constriction mid way down the abdomen giving the species a ‘club’ like appearance from above. Females have ochre-yellow abdomen and thorax but can develop with maturity some red along the mid-line and segment boundaries. The legs are black without the yellow stripes as in Common Darter (noticeable in the photograph opposite).

Status One of the less common species on the Reserve but as its range increases northwards should produce more records. Generally not as early as the Common Darter, emerging in summer and active from July through to November.
