Variation in sexual selection on male body size within and between populations of the soapberry bug
Article Abstract:
The influence of male body size on fertilization success in Jaedera haematoloma is investigated. The relationship between male body size and mating frequency in J. Haematoloma populations in Oklahoma and Florida is also studied. It is shown that the influence of male body size on the sexual selection process varies both within and between J. haematoloma populations. Male body size was an advantage in the aggregations studied in Oklahoma but not those in Florida.

Mutual preference for large mates in green stink bugs, Acrosternum hilare (Hemiptera: Pentatomidae)
Article Abstract:
A study has been conducted to examine mating behavior in the green stink bugs, Acrosternum hilare. Females were observed to prefer males of the larger size between two males in the absence of physical male-male competition. Likewise, males preferred to mate with the larger of two females. The results also revealed that females with large body size have higher fecundity. These suggest that mate selection in green stink bugs is determined by body size.
