Another What Creature made this thread.

Spotted this on a floor of a place I was working at, took a couple of pics then forgot about them.
It's in a wet screed thats set solid to cover underfloor heating pipes.
There was a cat that could get into the place so its possibly something the cat brought in, no cat tracks alongside them though.

Anyone?

Whereabouts are you? I have a very similar photo of beetle tracks in the Namib desert

That is one dang big beetle. Cockchafer?

Cumbria, Northern England.

I think the biggest beetle Ive seen locally has been one of those Cockchafer things and the photo was taken last May if that helps any.
I've never seen a Stag Beetle round here but that doesn't mean they cant be about, maybe?

Well, it seems that another name for Cockchafers is Maybug, so thats looking likely. Nice one.

Nice one, yeah that looks about right.
Whatever it was it was confused cos it walked in all directions.

Looks like Cockchafer is the most likely.

It looks like something of reasonable (relative!) weight. Whilst you say the screed was wet it has actually broken through the dried / set surface skin of the screed rather than sinking in.

A quick dip into a wildlife book suggests that the Maybug / Cockchafer is around 2.5 cm long and the tracks seem bigger that to me. I'm also intrigued by the parallel lines, I assume from some of its legs, with the separate sign further out from these.
