Yes, funnels and grass spiders look enough alike to pretty much be the same thing.
Just one wanders around and ambushes bugs without aid of a web, the other has that distinct tunnel web.
They can bite, but generally don’t.
Though I don’t take chances.
The bite is rather painful and can do awfully unpleasant things.
Allergies to bees or wasps increases the impact.
I went to put on my bathrobe the other morning...good thing it’s a pale color....spoted him parked in a fold was a funnel spider the SIZE OF AN ORANGE....in striking position. I never get freaked out at spiders. I FREAKED OUT!?! It was so huge and intimidating looking! Out he went....FAR FAR from the house.
