Synonyms and other taxonomic changes
Largus cinctus californicus Van Duzee 1923
may or may not be distinct from L. cinctus
~13 mm(1)
CA, CO, Mexico per (2), but not mentioned in (3) (which means that the species does not occur in Mexico, or, probably, not recognized as species at all)
Mostly plants (flowers, leaves, fruit) from a range of families, with a preference for lupines; not considered a pest of economic importance(4)
Life Cycle
see Booth (1990)
Halstead (1972), after examining "specimen from seven populations of L. cinctus ranging from Washington to southern Mexico", considers californicus a synonym of cinctus. However, Carl Schaefer (pers. comm. to HW) thinks that both species are valid.
