Biology
A
queen caste does not exist in ''Diacamma''. Unique to this genus, all workers emerge from cocoons with a pair of tiny innervated thoracic appendages (''gemmae'') that are homologous with wings. Mutilation leads to a permanent change in lifetime trajectory, because workers lacking gemmae never mate. This is unlike other queenless ants where workers establish a dominance hierarchy to regulate reproduction. In ''Diacamma'' only one worker retains her gemmae in each
colony, she is the
gamergate
Gamergate may refer to:
* Gamergate (ant), a worker ant that can store sperm and reproduce sexually
* Gamergate (harassment campaign), targeting women in the video game industry

(mated egglaying worker), and she bites off the gemmae of newly emerged workers. Mutilation causes the degeneration of the neuronal connections between the sensory hairs on the gemma's surface and the
central nervous system, and this may explain the irreversibility of modifications in individual behaviour.
