Irish Distribution

Mainly recorded from southern and south-western counties with scattered localities up the west coast to Inishowen in Co. Donegal. Its patchy distribution is difficult to account for but may be due to a sensitivity to grazing pressure in the lightly wooded habitats it prefers.


  • In Ireland it has been recorded mostly from light hazel scrub, along hedgerows and in scrubby pasture (Anderson, 1977, 1983, 1992b)
  • In Co. Waterford it is common near the coast in domestic gardens and along hedgerows

Red List status

  • Near threatened (NT).
