scientific name    Glyptoscelis albida    

habitat
Woody shrubs and trees. Specimens have been found in pine, fir trees, as well as willow (Blake 1967).

seasonality
Like others within the genus, this species is primarily found between March and July (Blake 1967). The Strickland Museum specimens were primarily collected between April and June, suggesting adults are more numerous during those months.

identification
6.5-10 mm in length, 3.3-5 mm in width, although there is great variation in size of species. Oval or oblong shape, as is typical within the genus and family. The have a bronze-black or purplish body with pale creamy brown setae all over. Head with a distinct median line ending in a depression in the middle front. Species has broad head with wide set eyes. The antennae extend below the humeri, and the seventh joint is long. The prothorax is wider than long, and coarsley punctate. The elytra are faintly depressed about the scutellum and have a transverse depression below the intrahumeral sulcus. Like G. squamulata, the pubescence on elytra are without lines of brown setae, and the pronotum is also lacking any pattern. Coarse setae are pointed and not truncate, as in G. squamulata. Ventral setae are finer than dorsal setae, and can be cream to light yellowish in colour. Dorsal and ventral pubescence does not completely cover surface, producing a grey-white colour and distinguishing it from others. Species diagnosis can be made with the aedeagus, which is triangular at apex (Blake 1967).

life history
Similar to other Glyptoscelis, the larvae mature underground and feed on the host plants. There is little sexual dimorphism; the genus as a whole tends to be quite homogenous (Blake 1967).

conservation
Nothing indicating that specimens are rare.

diet info
Like other members of the genus, adults are phytophagus, usually preferring deciduous trees and bushes. The larvae feed on the roots of host plants. (Blake 1967). Some Strickland Museum specimens were found on Artemisia tridentata (sagebrush).

range
Commonly found in southern Alberta and British Columbia, but range extends throughout much of the United States, as far south as California.

notes
Glyptoscelis albida is the type species of the genus Glyptoscelis.
