Curculio is a genus of weevils belonging the family Curculionidae and subfamily Curculioninae. Members of the genus are commonly referred to as acorn weevils or nut weevils as they infest the seeds of trees such as oaks and hickories. The adult female weevil bores a tiny hole in the immature nut to lay her eggs, which then hatch into legless grubs. In autumn, the grubs bore holes through the shells from the inside to emerge into the soil where they may live for a year or two before maturing into adults.
Dryophthorus is a genus of true weevils in the family of beetles known as Curculionidae. There are at least 60 described species in Dryophthorus.
Acmaeodera is a genus of beetles in the family Buprestidae, a group of metallic wood-boring beetles favored by insect collectors. Whereas most beetles including most buprestids fly with their elytra held out and vibrating their hindwings to give lift and thrust, Acmaedodera, however, fly with their hind wings only — the elytra are fused down the center and form a shield over the insect's abdomen, even during flight. This fact, combined with the banding across the abdomen which is common in this family, gives many of them a distinct wasp-like appearance when in flight. Several are therefore considered hymenopteran mimics.
