@Terry Thomas It is, I originally thought it was a Male Cupboard spider (Staeoda sp) but there is an hourglass pattern on it which is indicative of a red back. It isn’t visible in this photo due to it being extremely zoomed in, plus I took this photo with my phone camera.
@Terry Thomas I had it ID’ed on a very trustworthy Facebook page full of knowledgeable people, I’ve said it, the photo was taken on a phone so it’s very grainy added in that it is severely zoomed in.
Also I forgot to mention this is the underside of the spider.
@Terry Thomas the males and females look pretty different. The males are smaller and skinny, with white markings which can sort of be seen on the photo.
