Beetles
Beetles have hardened outer wings, giving adults a sturdy, armored appearance. Beetles feed by chewing, so damage includes holes, notches, tunnels, and chewed plant parts. The group includes leaf beetles, woodboring beetles, grubs, wireworms, and weevils. A few beetles are common pantry pests.
Fruit, flower, and bud beetles
Many beetles feed on fruit or flowers during their adult or larval stages.
Indoor beetle pests
Carpet beetles, wood borers, and pantry pests are among the most common beetles found inside homes
Leaf, stem, and seedling beetles
Many beetles chew holes in leaves and stems as adults. For some species, the larvae are also leaf feeders.
Root beetles
Many beetles, including grubs and most weevils, are root feeders in their larval stages.
Tree-boring beetles
These beetles bore into tree branches, twigs and trunks. Adults lay eggs on or in the wood, and larvae feed within it, often making distinctive tunnels or galleries.
