Andy, was this a big spider and do you have any other angles that you could upload ?

I don't know if I'm thinking along the same lines as Chris but it looks more like angulatus to me.

Agreed

I was thinking along those lines Alan.

Hi Chris,

I've got other photos, but all from more or less the same angle (I didn't want to disturb the spider which was high on the wall).

Yes, it was big - about 15mm (which persuaded me that it was probably diadematus. I'll have a look around and see if I can find it!

Shoulders

Looking at the original picture I'm seeing 2 pronounced shoulders (for want of a better word) on the abdomen. A side view would show these better and I'm sure Alan is right with A. angulatus.

Shoulders

Yes, I agree (would we normally call them 'love handles'?) but I am concerned at the lack of the 'knot' pattern, but as I don't know this species at all, then is it particularly diagnostic?

My thanks to Alan and Chris for correcting my original determination - I'm sure they are right!

Andy,

I'm not sure what you mean by the knot pattern - is that the white mark on the abdomen? Anyway, plenty of the pictures on the internet look similar to yours. And it doesn't look right for any of the other uncommon Araneus species (e.g. sturmi) or Gibbaranea.

Knot pattern

The whiteish abdominal mark shown in the Collins field guide looks vaguely like a knot - or maybe it's just me!
