Chlaenius alternatus

University of Alberta E.H. Strickland Entomological Museum

SeasonalityLarvae have been collected in early August. Adults have been collected in Alberta from mid-May to mid-July. IdentificationAdults: 10.5-14mm in length. Dorsal surface black and metallic though this can sometimes be faint. Pronotom often with a brassy or greenish hue laterally. Appendages black. Can be easily distinguished from all other Alberta species because all striae are broken at several points along their length; intervals are connected by convexities giving the elytral surface a transversely corrugated appearance; intervals 3, 5, 7, usually more convex. Setae behind pronotal shoulder are unicolorous, pale brown. Adapted from Bell 1960 and Lindroth 1963
