4 packets - you beat me by one!
I've been keeping half an eye on my ever-growing big Daddy of an Argiope. He's been in the same spot, web strung between two lavender bushes, for weeks now. I reckon if a Tarantula got ensnared in it, he'd become a monster food package - and I dread to think what size big Daddy would become.
Serious little question occurs to me...
Spiders can move around their own webs without getting stuck, but can they get stuck in the web of a different species?
