Multivoltine

Part of speech: adjective

Definitions

1. Describing organisms, especially insects, that produce multiple generations or broods within a single year, often adapting to varying environmental conditions
2. Pertaining to species capable of completing several reproductive cycles annually, resulting in numerous offspring cohorts across seasons
3. Relating to the biological life cycle of creatures that undergo frequent generational changes during one calendar year, enhancing population growth potential through repeated breeding events

Etymology: "Multivoltine" is built from the prefix "multi-", meaning "many," and "-voltine," a suffix that comes from "voltinism," a term used in biology for the number of generations an organism produces in a year. The "volt-" element traces back to the Latin "volvere," "to roll" or "to turn," which is also the source of words like "revolve" and "revolution." The idea is that each generation completes a turn of the annual cycle, so "bivoltine" means two generations a year and "univoltine" one. Biologists apply the term to insects such as silkworm moths and certain aphids, where the number of generations in a season determines how quickly a population can expand. A multivoltine species can produce several rounds of offspring before the year ends, so its numbers can climb far faster than those of a species that breeds only once.

Synonyms: many-brooded

Antonyms: univoltine, single-brooded
