Inner architecture of galls colonized by C. scutellaris and C. truncata. The effect of different colony composition and the presence of aphids are shown in the two halves of the gall: (a) gall still occupied by the cynipid; (b) Qa (queen and aphids), showing evidence (circled) of the chamber where the aphids were found (1); (c) Qwba (queen, workers, brood and aphids), showing evidence of an aphid chamber (2); (d) W, the gall was completely excavated by the ants and presented a main central chamber only; (e) gall colonized by a single C. truncata queen.
