Lepturinae

Acmaeops pratensis (Laicharting, 1784)

Linsley and Chemsak (1972) record the species from flowers of plants in 14 genera. In northern Idaho near the Canadian border, adults were collected on two plants representing NEW FLOWER HOST RECORDS: Boundary Co., 4.5 mi. W Copeland, 27-VII-1977, flowers of Melilotus alba, A. R. Gittens , (1), and 13 mi. W Naples, 9-VII- 1968, Sambucus blooms, W. F. Barr, (1).

Brachysomida atra (LeConte, 1850)

Linsley and Chemsak (1972) record the distribution as the Pacific Northwest to Colorado. Heffern (1998) included Idaho in the distribution of the species, apparently based on examination of specimens but without further information. We are not aware of other literature records from Idaho. However, its presence in the state is confirmed by 13 specimens collected in Adams Co., 6 mi. S Tamarack, 29-VI-1967, R. L. Penrose, (1); Blaine Co., 15 mi. N Ketchum, 20-VI-1968, R. G. Jones, (1); Butte Co., Craters of the Moon Nat’ l. Monument, 29-VI-1967, on Symphoricarpos oreophilus, D. S. Horning, Jr. , (4); Camas Co., 16.5 mi. N Fairfield, 18-VI-1966, A. R. Gittens, (1); Lemhi Co., Bannock Pass, 5-VII-1953, on Lupinus, W. F. Barr , (3) and Purshia tridentata (1); Owyhee Co., Indian Hot Springs, 20-VI-1966, A. R. Gittens, (1); and Valley Co., No Business Lookout, 17-VII-1969, W. F. Barr, (1).

Brachysomida californica (LeConte, 1851)

One specimen was collected in Adams Co., 2 mi. SW Mesa, 13-VI-1971, D. E. Foster. Linsley and Chemsak (1972) record the distribution as Washington and Oregon to central California. The single Idaho specimen was identified by the late Frank Hovore and represents a NEW STATE RECORD for Idaho .

Cortodera subpilosa (LeConte, 1850)

Adults have been collected from flowers of Achillea , Balsamorhiza , Lithospermum , Lomatium , Phacelia , Rosa , and Wyethia (Linsley and Chemsak 1972) . Additional specimens have been taken in Benewah Co., Plummer, 26-VI-1967, on flowers of Ranunculus, A. R. Gittens , (9); and Butte Co., Craters of the Moon Nat’ l. Monument, 7-VII-1967, flowers of Cirsium , (1), and Eriogonum heracleoides , (1), D. S. and C. J. Horning. These two collections represent NEW FLOWER HOST RECORDS.

Grammoptera subargentata (Kirby, 1837)

This is an abundant species in Idaho and occurs statewide. Adults are polyphagous and have been recorded on flowers of plants in 13 genera (Linsley and Chemsak 1976). The following collections represent NEW FLOWER HOST RECORDS: Butte Co., Craters of the Moon Nat’ l. Monument, 23-VI-1965, Ericameria nauseosa, D. S. Horning, Jr. , (1); and Canyon Co., 0.5 mi. S Middleton, 30-VI-1961, Heracleum, A. R. Gittens , (1).
