|Scolopostethus cf. affinis
A difficult genus including some common species; all have one large and several small spines on the underside of the front femur. The sides of the pronotum have a large and obvious pale spot just behind the middle.
The critical features in S. affinis are the short wing membrane, about 3X wider than long, and the antennal pattern; the 1st and 2nd segments are pale, and the 3rd and 4th segments dark (although the base of the 3rd is often pale also). It is sometimes found with fully developed wings (below), in which case the pronotum is generally narrower than normal. Common in leaf litter on a variety of soil, often below nettle clumps.
Compare: S. thomsoni, S. decoratus
