Chrysobothris rotundicollis Gory and Laporte, 1837

Nelson and Westcott (1976) wrote of this species (as C. blanchardi ): “… seems to be found primarily in the northeastern states… has not been recorded from the Rocky Mountains, but undoubtedly it occurs there.”Indeed it does; and based on its currently known distribution ( MacRae and Nelson 2003; Nelson et al. 2008) and recent results from trapping for woodboring insects in the Rocky Mountain region, notably from Colorado, it is widespread in that region. The following data confirm its occurrence in two additional Rocky Mountain states: COLORADO, Boulder Co., 39°58.797′, −105°30.881′, ±1.25 air mi N Nederland, 2554 m, Lindgren funnel trap w/ UHR and α-pinene, 28-VII-2011, RLWE, and vic. Lyons, 1795 m, 40.20099°, −105.28322°, 3-VIII-2012, T. Rowley, funnel trap w/ α-pinene & EtOH, ODAC; Larimer Co., Carter Lake Res., 1778 m, 40°21.03′, -105°13.457′, funnel trap w/ EtOH, 19-VI-2012, ODAC; 40.683267° −105.397967°, Hwy 14 W of Ft. Collins, 1855 m, 3-IX-2011, Funnel trap w/ α-pinene; 40.553°, −105.194°, 2112 m, vic. (W) Ft. Collins, 4-IX-2011, Funnel trap w/ α-pinene; Carter Lake Res., 8.5 mi (air) SW Loveland, 1780 m, 40.3505166°, −105.224283°, funnel trap w/ α-pinene, 4-IX-2011, TCMC, WFBM. IDAHO, Kootenai Co., Hauser Lake, Burlington No. R.R., summer 2009, Lindgren funnel trap; and Athol, funnel trap, 10-VIII-2010, WFBM; also Bonner Co., 48.000°N, − 116.733°W, Elev. 735 m, 3-VI to 2-IX- 2008, variably baited Lindgren funnel traps, NSCH, RLWE, UGCA, WFBM. This species occurs across southern Canada from British Columbia to New Brunswick, and in the USA from Washington and Arizona to Maine and Florida. Nelson et al. (2008) listed the legume Ebenopsis ebano Barneby & J.W. Grimes (Fabaceae) as a larval host for this species, but that is an error, and instead refers to C. rossi Van Dyke ( MacRae and Nelson 2003) , the species immediately preceding C. rotundicollis in the catalog ( Nelson et al. 2008), which species is known to breed only in dead wood of gymnosperms of the family Pinaceae .
