Description
Summary:The biology of Largus californicus (Van Duzee) in coastal southern California is reported. Eggs are laid on the ground in clusters of, on average, 130 eggs. Developmental time is approximately 14 days in the egg stage and 100 days in the five nymphal stages; adults live from 2 to 7 months. Dramatic changes in color occur. First instars are red, second through fifth instars are black, and adults are black with orange edges on the pronotum and wings. Nymphs are often found in clusters of >100 individuals. Adults are non-flying, and all stages feed mainly on plants but supplement their diet with feces and carrion. There are two generations per year, and adults overwinter. Some lizards find the bugs distasteful.
