Silpha tristis
Silpha tristis is very similar to the much more common Silpha atrata, but there are differences in size (tristis is slightly larger) and has more even puncturation on the pronutum and elytra. There are other subtle differences which aid identification. This adult was found on grass at Sherwood Forest CP in late May 2009.
