Nemastoma bimaculatum

Whilst grubbing about in dead wood and leaf litter on Sewbrec's excellent Woodlouse course yesterday (thanks Greg and Libby if you are reading this!) I came across a harvestman, Nemastoma bimaculatum.

 It's a new species for me, although it is pretty common and very widely distributed according to the Spider Recording Scheme maps. 

It's also one of the few harvestmen that is instantly recognisable due to it's black ground colour and the pair of white dots on the cepahlothorax.  With a body length of only 2mm or so they are quite tricky to find though!  I first thought it was a money spider until I spotted the typical gait of a harvestman and the characteristic tapping with the second pair of legs which are used as sensory organs.
