Gyne

Definition

In eusocial insects, the primary reproductive female caste, specifically a virgin or newly mated female destined to become queen of a new colony. Gynes are morphologically and physiologically distinct from sterile workers, typically possessing wings (alate gynes) before mating, larger body size, and fully developed ovaries. Following the nuptial flight, gynes shed their wings (dealate), mate with males (drones in bees), and either found colonies independently or return to establish themselves as queens within their natal colony.

Etymology

From Greek gyne, meaning woman or wife

Example

In honey bees (Apis mellifera), gynes emerge from specially provisioned queen cells, mate with multiple drones during nuptial flights, and store sperm for years of colony reproduction; a colony may rear dozens of gynes during swarming season, though only a few successfully establish new colonies.

Usage Notes

Distinguish gyne (potential/future queen) from established queen (reigning reproductive). Usage varies: some authors reserve gyne for unmated individuals, others use it broadly for all queen-caste females. Contrast with worker (sterile female caste) and ergatogyne (worker-like reproductive female in some ants). The term applies primarily to Hymenoptera (ants, bees, wasps); analogous concepts in termites use different terminology (primary reproductives). Polygyne and monogyne describe colony structure based on gyne/queen number, not gyne presence per se.
