Coccinella trifasciata

University of Alberta E.H. Strickland Entomological Museum

Common NameThree-banded Ladybug SeasonalityNo studies on lifespan exist, but like most Coccinellidae species, it has two generations in one year. It emerges during early spring. The second generation adults probably emerge sometime during summer. There may be some overlap between the two generations, but only the second generation will over winter (ADW, 2012). IdentificationThe subspecies C. t. perplexa (Mulsant) is commonly found in Alberta. It is 4.0-5.0 mm long. It is a round ladybug with reddish-orange elytra with three black bands. Middle and apical bands are interrupted and appear discontinuous (Acorn, 2007; Belicek, 1976). The subspecies C. t. subversa (LeConte) is found in Pacific states. The elytron of this close relative is usually not pigmented and only has the 1st of the three black bands (Johnson, 1910).
