Mine had caught a daddy longlegs in his little wingmirror web once, bet he was partying the night away behind my mirror thinking he was all set for a proper scoff. Tough titty, I brushed it off by the Sainsbury's roundabout in Portslade.
The little dickhead still spun another one the next day...
I've got a spider living in my wing mirror. Its a pain in the arse, keeps spinning its web between the door and the mirror. Even though I keep brushing the web away, sure enough next time I get in the car, he's spun another one and retreated back inside the mirror. Stubborn little tw@t.
