I wanted to photograph a Leaf-curling Spider and I arrived just in time to see a European Wasp hovering near the web, before it appeared to charge into the net. The spider seemed to move but then backed away. After taking the picture I started to set up a tripod keep photographing. By the time I was ready with my tripod, the wasp had gone, while the spider was backed right up in its leaf. I looked up the behaviour on Canberra Nature Map, finding two cases where European Wasps had stolen, or attempted to steal prey from a spider’s web (https://canberra.naturemapr.org/Community/Sightings/Details/4205871 & https://canberra.naturemapr.org/Community/Sightings/Details/3374617). I think that is what happened in this case given the wasp looks like it has its legs wrapped around something in the web.
