Yesterday I spotted what looked like a brown blob on my car, on closer examination it was a dense ball of tiny baby spiders.
I took a piece of paper and coaxed the blob onto it, it seemed to stay put so I started walking towards the garden to transfer it to a bush. All at once the blob split up and a whole load of spiders were going in all directions...I managed to shake the paper over some shrubbery and they all went everywhere.
Just now I looked to see if any were still around and this is what I saw at the top of the shrub:
The Blob is reconstituted.
So if a predator came along it could eat a whole load of spiders in one go. If they were scattered around it seems much more likely that some would make it. So what's the evolutionary advantage of making a blob?
