The effects of a range of developmental photoperiods on adult dimorphism in Thyanta pallidovirens accerra were studied under laboratory conditions. Adults reared in photo- phases of 14L and higher had short pubescence and those in 12L and lower, long pu- bescence. No dimorphism in color was produced in these same photophases.
