Been out for a short walk with me torch this evening; the plan was to wander about until indistinct black carabidae scuttled into view and then pot them up. It just about worked - I saw three beetles and potted them all, I guess I just hoped for a bit more activity after a good warm day. Under the microscope and trying to piece together various info resources, I think they are three different common species. Click for the beetles for a bigger image (though once again rushed shots in the dish - haven't got the time or patience to properly photograph beetles which won't sit still unless under duress).
Pterostichus madidus - red legged form
melanarius ? madidus - black legged form
Skev, the bottom photo is just the black-legged form of Pterostichus madidus. Both your madidus photos show the rounded hind-angles to the pronotum really well. The only 2 other Pterostichus with rounded angles are aterrimus (extinct in Britain, survives in NI) and aethiops which can normally be excluded on range (a northern and western species).ReplyDelete
Thanks again Mark - appreciate the help. I find a lot of these aspects subjective until I've seen enough specimens/species to get a feel for some of the differences. Feels like when I started looking at micromoths a good few years ago. Still, I'm happy with 66% correct!ReplyDelete
