Definition of Univoltine

A univoltine species is a species that has one brood of offspring per year. Many species try and coincide their life cycle with that of another species (such as a food plant) on which they rely. Some univoltine species have long-lived adults.

In the UK many species of dragonfly are univoltine. Adults emerge in early summer, mate and lay eggs. The larvae then develop (this can take some years) before eventually becoming an adult. However there is only one new brood of young each year.
