scientific name    Cleonidius frontalis    

Grassland to desert; elevations between 339-3130 m (Anderson 1987).

Adults active January until November (Anderson 1987).

According to Anderson (1987, Fig. 144c), C. frontalis has denticles on female fore tibia. Irregular patches of larger white scales (not vittate) on elytra (Anderson 1987). Hindwing longer than elytra (Anderson 1987). Prementum of rostrum is ventrally swollen and rostrum cross-section circular (Anderson 1987, Fig. 144b). No curved sulcus (groove) behind the eye (as in C. poricollis) (Anderson 1987). Developed postocular lobes (vs. C. trivitattus) (Anderson 1987).

life history
No specific information for C. frontalis; however Cleoninae larvae mine plant roots (Anderson 1987). A similar species (C. trivitattus) is monophagous; adults feed on the same host plant as the larvae (Thompson et al. 1995).

Not on provincial or federal (COSEWIC) lists for species at risk.

diet info
Anderson (1987) suggests associations with Atriplex sp. (saltbush) and Melilotus sp. (sweet clover).

In Canada this beetle is found in Alberta east through Manitoba. In the USA it is found in California, Nebraska, and Kansas to west Texas (Anderson 1987).
