Subfamily Baridinae

Identification

Most baridines are glossy and black, with few (usually white) or no scales on the body, and are most readily recognized by an ascended mesepisternum that is visible between the hind angle of the pronotum and the elytral humerus. (1)

Life Cycle

The natural history of baridines is poorly known. Some species are associated with monocots such as various grasses, sedges, and palms. Larvae mostly mine stems. Some spp. appear to be associated with fungi on dead wood. Many baridines can also be found in semi-aquatic habitats. (1)

Remarks

Among all weevils, those in the Baridinae are in need of the most study. Many of them are still known only from type series and localities. Thomas Lincoln Casey was the last person to seriously study this subfamily and is responsible for most of the genera and species concepts and names in use today. (1)
