single host species, it might not apply to situations where the bean species differ. This paper reports an investigation into a potential effect of larval host on adult fitness in C. maculatus. The effects of larval host type on female fecundity, independent of any effect on emergence size, were examined. Beetles were raised in two hosts (black-eyed bean and mung bean), and their lifetime fecundity and elytral length were measured. The relationship between fecundity and size for beetles raised in each host type was compared.
