摘要：

Abstract. 1. A simulation model is presented which describes, from field‐estimated parameters, the effects of daily survival rate and proportion of sunny days on the lifetime egg production of females of the damselfly Coenagrion puella (L). 2. Lifetime egg production increases with daily survival rate and proportion of sunny days. 3. Estimates of mean lifetime egg production per female in bad and good summers in northern England ranged from 333 to 740. 4. The distribution, as well as the proportion, of sunny days influences lifetime egg production. For a given combination of daily survival and proportion of sunny days, lifetime egg production decreases as the distribution of sunny days becomes more clumped. 5. Lifetime egg production is largely determined by chance; females who begin their mature adult life during a period of sunny weather can produce many times more eggs than those whose mature adult life coincides with cloudy days.
