General Appearance

Small bat, with long shaggy fur, usually frosted appearance from pale hair tips on back, paler ventral than dorsal surface

Similar Species

Other bats.Differentiated from other bats not Pipistrelles by:
  • Simple nose shape (no horseshoe)
  • Ears well separated from one another at base
  • Post-calcarial lobe present on membrane
  • Forearm less than 37mm long.

Distinguished from Pipistrellus pipistrellus - Pipistrelle by:

  • Larger.
  • Forearm length 32-37mm.
  • Length of first digit from wrist to tip divided by forearm over 1.25 (versus less than 1.25 for Pipistrellus pipistrellus).
  • Dental differences: incisors taller and thinner, with distinct gap between second and third lower incisors, also third upper premolar larger, extending well beyond cingulum of canine tooth.
  • (B142, B167)

Dental differences required to separate from other Pipistrellus spp. (B142)

Nests / Burrows / Shelters

Roosts:
  • Summer: hollow trees, bat boxes, bird boxes. Also buildings (wooden churches, residential buildings).
  • Winter: cliff crevices, hollow trees, cracks in buildings

(B143)

  • In Czechoslovakia roosts in crevices in walls, also under roofs of isolated buildings near ponds/at periphery of woods (B142).

Distribution and Movement (Migration etc.)

Normal
  • Western Europe (rare) to Urals, Caucasus, western Asia Minor (north-east India, to southern China).
  • Central and southern European portions of former USSR have highest population density.

(B51, B142, B143, B147)

  • A single Nathusius's pipistrelle was found in Belfast in 1996 and breeding colonies were found in Northern Ireland in 1997. It is probable that they have been present for some time but previously have been confused with common pipistrelles (Pipistrellus pipistrellus - Pipistrelle (Species)).(V.w58)

Movements:

  • Highly migratory usually in northeast-southwest direction; generally recorded with movements of over 1000km, and maximum recorded movement 1600km (B142); 1905km (B143).
Occasional and Accidental Britain; most likely to be seen in autumn and winter (B142).
Introduced

Conservation Status

Wild Population -
(Importance)
  • Distribution patchy.
  • Assumed rare over most of Europe, but may be more common than previously thought.

(B143)

  • In Britain: probably a migrant winter visitor, but may breed in Britain. Population estimate: unknown number; records few, mainly of individual bats recorded in May or September (B221).

General Legislation
  • Bern Convention, Appendix II.
  • Bonn Convention, Appendix II.
  • EU Habitats and Species Directive, Annex IV.
