Abstract: Populations of the alfalfa caterpillar, Colias philodice eurytheme Boisduval, reach very high numbers during the more favorable summer months in California. This study was conducted to determine the important factors affecting egg production and oviposition, and their corresponding effects on population trends of this insect. The reproductive system of the female does not differ greatly from those of other Lepidoptera with two genital apertures. Mating usually occurs a few hours after emergence, and involves the passage of a spermatophore which is formed in the female from the glandular secretions of the male.
