“‘Accounts of a giant spider invasion have been greatly exaggerated,’ announced the town’s new mayor, Mrs. A. Rachne. A further press conference is scheduled for this evening in her parlour.”
They whistle when you get near them? Bizarre.
A lot of spiders do that, actually. Usually only the larger ones are audible, though.
Hey! ONE big, hairy, venomous, barking spider ,bigger than you hand ,IS an invasion!
I think it’s more a case of the spiders who already live there being less discrete and more visible than usual, rather than foreign spiders moving in. So it’s more a “coming out of the closet” thing than an invasion thing. Perhaps literally.
