Egg size and reproductive allocation in the pitcherplant mosquito Wyeomyia smithii (Diptera: Culicidae).
Adult longevity and lifetime fecundity, but not fertility, of northern (Maine, USA) Wyeomyia smithii (Coquillet) increase with female pupal weight. Mean egg size does not vary with pupal weight, but the standard deviation in egg size shows a marginally significant increase with pupal weight. Egg sizes are not skewed but are leptokurtic in their distribution; neither skewness nor kurtosis changes with female pupal weight. Mean egg size is not correlated with weight-specific adult longevity or with weight- and longevity-specific lifetime fecundity. Reproductive effort early in adult life does not affect longevity, reproductive effort late in life, or reproductive rate late in life. Finally, there is no significant correlation late in adult life between weight-specific rate of egg production and the size of eggs being produced. Egg size does vary within females but is not a variable entered into the physiological allocation of resources among survivorship, fecundity, or rate of egg production.
