Cryptocephalus umbonatus Schaeffer 1906

umbonatus (L). 'a projecting knob; a shield' (1)

Size

Length: 4.0 to 6.0 mm (2)

Identification

White (1968) describes the elytra as "...striae red to black, with no markings." (2)

In the types and in many of the other specimens on hand in the USNM, the elytra are waxy yellow, and the striae black and strongly contrasting with the background. In nearly half the other specimens, however, the elytra are rather to quite orange, and the striae partly to completely dark reddish and less strongly contrasting with the background. At the extreme, the elytra match the orange color of the pronotum. (2)

CA - AZ (3), all 46 specimens in USNM from AZ (2)

Food

Schaeffer (1906) reports this species beaten frequently from oaks, Quercus (Fabaceae)

Remarks
