Ponds and other still, stagnant or even brackish waters are used and they are frequently found at small garden ponds. They are frequently found away from water, resting on the tops of plants in woodland rides.

Status & Distribution: 

Abundant in England, Wales and Ireland. Less common in Scotland.

Similar species: 

The various resident and migrant species of Darter in the UK are easily confused, the females being particularly difficult to tell apart. The yellow stripe on the legs and the orange-red (rather than blood-red) appearence of the mature male help to distinguish it from the Ruddy Darter

  • Males are larger, more orange and less waisted than Ruddy Darter, with yellow stripes on legs
  • The commonest darter, found in all habitats
  • Like to perch on pale objects
