摘要: In southeast New Brunswick the chironomid, Metriocnemus knabi, an inhabitant of aquatic system contained within leaves pitcher plant, Sarracenia purpurea, show seasonal fluctuations in numbers related to emergence and colonization, but density is usually correlated with potential volume leaves. Females from a May oviposit into overwintered produce generation which emerges August prior deterioration The progeny develop current summer growth do not emerge until following July. Ovipositing by this can be or newly opened Larvae that begin development leaves, progressive during later autumn, migrate younger have achieved complete colonization. July produces May. Thus, there appears two cohorts population, each ...
