(191ENnic) Entomobrya nicoleti (Lubbock 1867)

Entomobrya nicoleti is widespread and very common and reaches 2 mm in length (Figs. 1 to 3). This species is frequent under surface debris such as recently fallen branches and similar sites at ground level, rather less so up exposed surfaces (compared to E. nivalis).  Steve Hopkin observed that many UK specimens have much less pigmentation than that shown in diagrams in the literature, but that the two dark spots of pigment on the posterior margin on either side of the midline of the fourth abdominal segment are always present.

 

More recently, some online images of surface-dwelling Entomobryids show this species, again distinguished by the paired dots each side of abd 4, such as this image.
