what level weedle evolves
Evolved from: Weedle (at level 7). Evolves into: Beedrill (at level 10). Locations: You can catch Kakuna in Blue/Red on Route 24 and 25 as well as in Viridian Forest. You can also evolve it from a Weedle (which is really what you should do), however, in Red and Blue, a Kakuna evolved from a Weedle will not learn harden. Kakuna is not in Pokemon Yellow.
