(192ENniv) Entomobrya nivalis (Linnaeus, 1758)

*annulata (Lubbock, 1862)
*macrocerata Bagnall, 1916
*nigromaculata (Templeton, 1835)
*pulchella (Ridley, 1881)

Entomobrya nivalis (Figs. 1,2) is extremely common and widespread. It is frequently beaten from branches and flowers, is a major component of the canopy community in many forests and has a high resistance to desiccation. It is often found on the external window sills of houses where the springtails presumably graze algae from the surface of the paint. They are often found indoors.

 

 The pattern on the body is distinctive, but see E. intermedia with which it has been hopelessly confused in the past.  Steve Hopkin himself has produced photos labelled E. nivalis but whose colour pattern is actually closer to E. intermedia.  


Entomobrya nivalis must surely be present in every hectad on the map, except perhaps for the summits of the highest mountains. In fact its apparent patchy distribution is a good indication of the extent of under-recording of Collembola in Britain and Ireland.
