Webspinner
From Multiversal Omnipedia
Webspinner is the Umbrella Corporation BOW codename for a spider that has grown to gargantuan proportions due to contact with the T-Virus. Webspinners behave like normal-sized spiders for the most part, and they are capable of scaling walls and spitting poison. When an adult Webspinner dies, several baby spiders spring forth from its egg sack.
