Here's the nest - it's shape is slightly typhoon like. And it did survive all that rain that you correctly predicted as well as some surprisingly big wind gusts.

Had the grass cutter guy here today - he says he gets stung at least once a year and he is understandably wary of them. He says, the black tiger head is the most shon. He wouldn't, quite rightly, cut the grass near them in the day. Instead he waited till dark and i set him up with a headlamp and he did that area and got through unscathed. Anyway, he advised me to stay indoors for 7 days after the nest is removed. He says there will be some that escape and they will hang around and sting anything with a human scent that they come across anywhere in the vicinity.

Today i observed one buzzing around my house and squirting out a liquid - i assume this is a pheromome marking of some sort. They are fascinating, but quite scary creatures.
