General Appearance

Small bat. Fur shaggy, wings narrow, membranes black/dark brown, translucent, shiny; nose and ears black/dark brown. (B142, B167).

Similar Species

Distinguished from non-Myotis bat species in Britain and Ireland by combination of:
  • Simple form of nose
  • Wide-spaced ears
  • Lack of post-calcarial lobe to membrane.

Distinguished from other Myotis spp.:

  • Forearm less than 50mm long.
  • Ears less than 18mm long
  • Tail lacks 1mm long stiff bristles.
  • Foot about one third length of shin, calcar half of foot-tail length, fur shaggy black/brown with paler tips
  • Ear/nose dark brown, tragus bluntly pointed, outer (posterior) edge usually convex, penis of males thick, club-shaped.
  • N.B. may be very difficult to distinguish from Myotis mystacinus - Whiskered bat (B167).

Distribution and Movement (Migration etc.)

Normal
  • Exact distribution uncertain due to confusion with Myotis mystacinus - Whiskered bat. (B142).
  • Palearctic: from Britain, Spain and eastern France eastwards to Kamchatka Peninsula, Korea and Japan (Hokkaido).
  • Southern extent in Europe to south-eastern France, central Italy, Bulgaria. North to 65°N.
  • Britain: widespread in England and Wales; also southern Scotland (B143)

(B51, B142, B143, B147)

Movements:

  • Winter movements of 2.5 km recorded (B142).

Conservation Status

Wild Population -
(Importance)
  • South-eastern Europe patchy distribution,rare.
  • Northern Europe widespread and common.

(B143)

  • In Britain: native, common in west and north England but elsewhere rare or absent. Pre-breeding population estimate of about 30,000, including 22,500 in England, 500 in Scotland, 7000 in Wales. Population estimate is that little information available; data believed to be "within the right order of magnitude". (B221)
