Lesser Stag Beetle

Dear B Woodward,
This is the female of the largest and arguably most distinctive beetle found in the UK, a Stag Beetle,
Lucanus cervus.  Stag Beetles have become increasing rarer in the UK in recent years and in many areas they are protected.  Here is a matching photo on the Space for Nature Garden Biodiversity Forum.

Correction:  Lesser Stag Beetle
Thanks to a comment by mardikavana, we are correcting this posting.  This is actually a male Lesser Stag Beetle.

    This beetle is a male Dorcus parallelipipedus. Compared to greater stag beetle, the lesser stag beetle is smaller (especially males compared to lucanus cervus males because they do not have so great jaws) and darker (black compared to brown). It is sometimes hard to distinguish between the two species because there are Lucanus cervus females who have black body color. The best way to do it is to watch the middle tibia. Lesser stag beetle has 1 spike on it but greater stag beetle has 3 spikes.

      Thanks for the correction Mardikavana. We always appreciate your input. We wondered if perhaps this might be a Lesser Stag Beetle, but the angle of the photo was so odd, we were uncertain.
