I'm one of those pathetic bastards that gets out of his seat and waves his hands around his head at the very sight of them. Everyone's got a friend like him it seems - we ruin many a day out. But this year I've seen something that I've never seen before, and I've seen it 4 times... twice today. And that's wasps attacking other insects. I've googled it, and it was mentioned once or twice in 10 years.
I first saw a spider on a cobweb minding its own when a wasp just swept on in, wrestled with him and swept him away. I'd never seen that before. Then, some weeks after I saw a similar fight. Then, today, I saw two scraps with flies, in the exact same area, the latter battle lasted 6 minutes, with the wasp expertly beheading him with its mandibals, then removing all of its legs, then separating its thorax before it sucked out what juice there was left in it.
Anyone else seen this?
