I often see a wasp in summer, dragging around a spider larger than itself, whose legs it has have ripped off the spider’s paralysed body. The wasp places the body in its egg chamber, all nice and fresh for the wasp’s larvae to eat when they hatch. Horror movie stuff, but that’s Nature sometimes. She doesn’t have human morality.
But occasionally it’s the other way around. I found this struggle on my umbrella yesterday.
The huntsman was about 3 cm from tip of cephalothorax to tip of abdomen – a medium size for our subtropical species. They are great at keeping cockroaches in the house down, too.
This spider would have been fast to catch the wasp, and it is a fast hunter, but perhaps it was inspired by the thought of all its paralysed brethren.
