We’ve had them for two years. Never seen them parachute, ever. Some say no sting, others say nasty like a hornet sting (bite actually.)
Their webs are golden in the sunlight. Some of the females can span 4” legs to legs.
Nothing seems to eat them.
Annoying and invasive. But not OMG.
Spiders seem to be their favorite food.
That is interesting because its legs look just like those of Florida’s native Banana spider/Golden orb weaver spider, which produces incredibly strong gold silk. Harmless, but I get a graceful of their web at times when mowing. The cool thing is they have the sense to rebuild their webs higher up if it gets destroyed that way.
