Size...

If I may point out, your sizing is na bit out. For instance a Dor Beetle is around 1cm or so long as is a Dung-fly.

Sorry about the sizing Peter,

Sorry about the sizing Peter, i was working from memory which may explain these errors. however the Dor Beetle was definatly much larger than 1cm.

The Dor beetles range in size

The Dor beetles range in size from 12-26mm in length, so 2-3cm would be a pretty reasonable estimate!

probably spinger

I'd agee with rimo that this looks more like spiniger than stercorarius, on the grounds that stercorarius is usually a bit more shiny, but I can't be sure of it. See information at:

You may well be right about ....

You may well be right about spiniger.But might I say that the reason I mentioned sizing was (unless I have become delusional)originally the Dung-fly was estimated at 2-3 cms long and the Dor beetle at 4-5cms long.Perhaps Iam wrong in which case Mea culpa or perhaps the originals were edited.Hugh might enlighten us.

Don't worry Peter, you arent

Don't worry Peter, you arent becoming delusional. I merely edited the sizing for the specimins after you pointed out the issue, then posted the above comment apologising for my errors. Sorry for the confusion that may have been caused

So similar.

i think the G. stercorarius is the more likely candidate, the elytra stripes are less prominent in G.spiniger and is a deeper blue.
