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).
Scientific Name
Coccinella trifasciata
Common Name
Three-banded Ladybug
Habitat
Alfalfa fields, peach and apple orchids, parklands and boreal forest were the preferred habitats before the arrival of C. septempunctata. Now more of a habitat specialist (Belicek, 1976; Hodek & Honek, 1996).

Not much is known about the life history of this species, but much can be extrapolated from its close relative Coccinella transversoguttata. Adult females will lay eggs when the average temperature is around 120C. The larvae have four instars before it pupates. The adult will emerge during summer. Not much is known about reproduction, but adults can mate multiple times with different partners (ADW, 2012).
Conservation
Decrease in relative abundance due to competitive displacement by C. septempunctata. No evaluation, but may be a candidate for future conservation efforts.
Diet Info
In a laboratory test, it did not seem to be picky (Belicek, 1976). Although it can feed on pollen, it needs more to finish its developmental stages. In an experiment the larvae ate various nymph leafhopper species…

Range
Extends throughout most of North America, except northern Canada, northern Alaska and Pacific coast. C. t. subversa on the other hand is found in Pacific Northwest (Belicek, 1976; Kits, 2005).
