open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Our article reports, to our knowledge, the first observations of inquiline gynes performing worker tasks for their host colony. We dissected these gynes to establish that they were all unmated. We hypothesize that nest excavation by social parasites represents an artifact of a non‐parasitic past.

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
