Hi Rob, Just realised something rather interesting. The picture you show is a different S.hardwicki to the one we had (up till a few days ago). Here is a pic of the one we had last year http://www.martin.chaerilus.co.uk/photogallery/Originals/Misc/S.hardwickei1.JPG. Note the second segment is red on your one but is black on ours. We have now had one that looks similar to the one you have. It seems thinner so I initially wondered if it was a male and our original one a females. Alternatively its a subspecies. Are the ones you have all the same or mixed?
