Trigonopsis cameronii females often work in groups of up to four individuals on single nests, and because of inbreeding and a tendency to return to the mother nest, nestmates are likely to be highly related. The altruistic behavior associated with group living, most notably the failure to steal prey from nestmates, can thus be explained by kin-selection theory.
