These curves indicate that the population of Hexagenia nymphs in the St. Marys River is composed of two year classes or cohorts. One cohort emerges per season, 2 years after egg deposition. This 2-year life cycle contributes to the stability of the food chain by providing a relatively ...
It is shown, that rare European species Metreletus balcanicus has monovoltine life cycle within the region, and overwinters at the egg stage (Us). It is established, that ovoviviparous Cloeon dipterum has 2–3 generations per year (MB-MP) within Eastern Ukraine; the voltinity depends ...
