Where do White Pine Weevil pupae develop?

White Pine Weevil pupae develop beneath the bark of the tree where they have fed. As larvae, they create tunnels that can lead to their pupation phase, typically just under the bark. This location provides both protection and the necessary conditions for their metamorphosis.

The development of pupae in woodchips does not occur because woodchips do not offer the structural environment or moisture necessary for the life cycle of these insects. Thus, the correct environment for the pupation stage of White Pine Weevils is the bark of the tree, where they can continue their lifecycle until emerging as adult beetles.
