Devils Coach Horse
Fairly certain this is a Devil’s Coach Horse, although happy to be corrected. Spotted it scurrying along the side of the pavement outside our office near Glasgow, Scotland. It was definitely fierce and kept doing its scorpion pose and waving its jaws. I really struggled to get a photo from anywhere but the back because as I maneuvered round to get a photo from the front it kept turning to face its tail towards me! I read on the ‘net that they grow up to 28mm – however I am convinced this one was more (I am ashamed to admit I have come to this conclusion from using the pattern of stones in the photo to identify where it was taken and then measuring various distances) any info on maximum length? Great site! Cheers,
This is indeed a Devil’s Coach Horse, a type of Rove Beetle. This European native was introduced to Southern California in the 1930s and it has adapted quite nicely. We frequently find them in our garden where they eat snails. Hogue lists body length at 33mm.
