Siagonium quadricorne
...
Known more commonly as Rove Beetles, Siagonium quadricorne is just one of over 1000 species of Staphylinidae in the UK. Most are scavengers and can be found in a variety of sites, but this species is often found underneath moist bark. Siagonium quadricorne measures around 5mm long, with the male having well developed horn-like projections. The jaws are large, giving a four-horned appearance. This pair were found underneath the bark of some felled Sycamore logs at Sherwood Forest NNR in December 2008, where there appears to be no previous site records.
