This small group of tree-infesting beetles formerly was placed in its own family, the Platypodidae, but has recently been included in the Curculionidae. The females burrow into hardwoods and conifers to create narrow galleries in the wood, then introducing a fungus that grows within the galleries as food for the beetle larvae.
These are fairly uncommon beetles that do little damage to trees. Preventive sprays of residual insecticides may be applied to the bark prior to adult beetle activity. The feeding galleries of the beetles may occur in finished wood products where the milling process exposed the galleries. The beetles will not live in structural lumber, and the damage present is only from the standing tree.
