Grub on Spider

Grub on Spider

DescriptionSaw this spider and automatically grabbed a picture of it, then realised the white collar was actually a grub or caterpillar that seems to have wrapped itself facehugger style round the spider.  I didn't have the tripod and this is a small spider in a big web, so moving around in air currents, so impossible to stack.  I walked on and came back later and the spider was happily moving around, with the grub still in place, so it wasn't dead as I first thought.  Another case of odd behaviour that I don't understand.  I presume the grub crawled on the spider when it was on a leaf, not on the web, but whether there is some predation here one way of the other I don't know.  It's possible the grub is hiding in plain sight, by wrapping the spider it can't be attacked, maybe? Don't know.  Both were gone the next day and no sign of the web.  Possibly the creepiest picture I've ever taken.
