Unknown Hiding Place

Funny you say that, most truely science minded folks would have brought one home and waited for what ever is inside to hatch out, then we would know right?
Well take into account a biology teacher goes abroad to somewhere in Europe, I think in the 60's or 50's not sure, she finds loads of lovely things to bring back to show the kids. She has a strange seed pod/egg sack, they let it hatch out in the name of education and science and it turns out to be Wasp Spider (Argiope bruennichi). She doesn't know what else to do with them so she realeases them into her back garden. Today they are widely spread across the country, especially in the south.
I remind this is an island so when we get a species introduced in such a way generally speaking its bad news for the native flora and fauna. Luckily this invation has had little imapact on the native spiders and has its own niche to eat grasshoppers and crickets here, and well they are fabulous spiders to photograph as well.
Some things have not turned out so well.
