Spinarak shook her head, no. Ariados don't fly, even though they have two wing-like things on their backs. They were legs and Spinarak certainly didn't know how they would use those two legs.

"...They get a little faster...on web...and stronger." Spinarak replied, feeling slightly sad about not being able to fly. She had no intention of evolving, though; Ariados were usually feared by Pokemon for its poison and of how they were predators, and Spinarak didn't really like being labeled as a "bad guy."
