Seasonal development
and life cycle—Bean weevils
Weevil eggs may be glued to the bean or the pod (cowpea weevil), glued to green pods (broad bean weevil),
or laid loosely among beans or through cracks in the pods (bean weevil). The larval and pupal stages are
spent inside the bean. Adults emerge from beans through a round hole in the bean seed coat. Bean weevil
infestations can start in the garden or in trash beans. Damage is a combination of feeding and contamination.
