A robust looking damselfly with a dark greyish abdomen and a blue "tail" in the male. The eyes of the male are deep red and the thorax in both sexes is bronze black on top. The female has short, yellowish ante-humeral lines.
Found in lakes, gravel pits, canals and slow-flowing rivers. The males often sit on water lily leaves defending their leaf from allcomers.
Status & Distribution
Locally common in southern England and the Welsh Borders.
The similar, but smaller, Small Red-eyed Damselfly is sometimes found in the same habitat and careful observation is needed to distinguish the two species. Could be confused with the Blue-tailed Damselflies Ischnura elegans and I. pumilio, but these are smaller less robust looking insects and do not have red eyes.
