When two hives of Combee meet, their natural inclination is to join as friends. Only one Vespiquen is able to lead the new cluster though. If Combee is captured, they demand to be kept busy all day.

Vespiquen pheromones can control Beedrill and Ribombee almost as well as Combee. If enough congregate, Vespiquen can become an environmental nuisance — at least surrounding plants thrive!
