Ischnura elegans (van der Linden, 1820)
Blue-tailed Damselfly.

Adults. Adult body about 27–31–35 mm long. Average wingspan 35 mm; hindwings 14–20 mm long.

The eyes lateral and widely separated; black and blue, or green and blue (usually dark, with a circular blue (rarely yellowish or greenish) spot at the rear, in both sexes). The front of the head immediately interior to the eyes pale whitish blue.

Legs black and blue ((-ish) below). Hind tibia without a featherlike expansion. Thoracic antehumeral stripes present (usually, humeral stripes also visible), or absent (in varieties with a rose-pink or brown thorax); blue, or violet, or green (-ish). The wings held vertically in repose; similar in shape and venation; petiolate; unpatterned and clear. The inner wing venation blackish. Discoidal cell a simple quadrilateral, not longitudinally divided (trapezoid, without transverse veinlets). The wings exhibiting 3 psqs cells between the quadrilateral cell and the subnodus. Antenodal veins in the forewings 2. Pterostigma elongated but only about about twice as long as wide to well over twice but no more than five times as long as wide (teardrop-shaped, the same size and shape in forewings and hindwings of both sexes); black and yellow, or pale with a dark centre (yellow, or yellow and black to dark blue internally in forewings and hindwings of the male only?). The hindwings with only one row of cells distal to the pterostigma between the costa and the radial vein.

Abdomen linear from base to tip, or linear from base to tip to linear from a conspicuously swollen base (slender); 22–29 mm long; predominantly black (marked with narrow intersegmental yellow bands, and posteriorly with blue or brown); predominantly transversely banded (generally both sexes with thin yellow intersegmental bands, and with segment 8 light blue or rarely brown); without mid-dorsal spots. The male abdomen without auricles on segment 2; with paired inferior anal appendages. Abdominal segment 8 of the female with a ventral apical spine (this small).

Nymphs. The nymphs elongate and slender-bodied, gradually tapering posteriorly; when mature, 21.5–25 mm long.

The head in dorsal view markedly narrowing from immediately behind the eyes. The postocular lobes curving sharply to the back of the head from some distance behind the eyes. The antennae with the scape considerably shorter than the other segments taken together; with the first flagellar segment longer than the pedicel. The mask narrowed gradually to the hinge; without a median cleft. The prementum bearing 8–11 major setae (4+4 to 6+5). The body of the labial palps bearing 6–7 major setae. The outer margins of the labial palps without spines. Distal margins of the labial palps crenate and coarsely toothed. The moveable hooks of the labial palps without setae. The apical combs of the tibiae mainly of trifurcated setae.

Classification. Zygoptera; family Coenagriidae.
