Summary Reproductive properties of the oriental chinch bug, Cavelerius saccharivorus , were investigated for three types of female adults: brachypters produced in both high and low density populations and macropters produced in high density populations. With respect to egg‐laying potential in terms of clutch size, clutch number, and total fecundity, macropters were superior to brachypters produced in the same high density population, although inferior to brachypters produced in the low density population. The mean fecundity of female adults in each type was positively correlated with mean body length. Macropterous females markedly prolonged their initiation of both copulation and oviposition and had a much longer life span compared with both types of brachypters. However, there was no fundamental difference in reproductive schedules between the two types of brachypters.
