Caenopsis

Caenopsis is a genus of broad-nosed weevils in the beetle family Curculionidae. These weevils are typically small and found on various host plants depending on the specific species.

Characteristics

Caenopsis weevils, like other broad-nosed weevils, are characterized by their short, broad snouts (rostra) compared to the long, slender snouts found in many other weevil groups. Their antennae are geniculate (elbowed) and clubbed. The body shape is generally oval or oblong. The coloration can vary depending on the species, ranging from brown and grey to more vibrant hues.

Distribution and Habitat

The distribution of Caenopsis species is dependent upon the specific species. They are generally found in temperate and subtropical regions. Their habitat is closely tied to the availability of their host plants.

Ecology

Caenopsis weevils are phytophagous, meaning they feed on plants. The larvae often develop within the plant tissues, while the adults feed on leaves, stems, or flowers. Certain species may be considered minor agricultural pests, although they rarely cause significant economic damage. The life cycle involves egg-laying on or within the host plant, larval development, pupation, and the emergence of the adult weevil.

Classification

Caenopsis belongs to the subfamily Entiminae within the family Curculionidae. The taxonomy within the genus can be complex, and the exact number of species is subject to ongoing research and revisions.
