D. melanogaster females respond to their social environment by using tactile/gustatory sensory pathways. A Olfactory restriction through antennal removal. Intact focal females (‘control’) and olfactory-manipulated focal females with no third antennal segment (‘antennaless’) were kept in isolation or in a group with three intact non-focal females. B Olfactory restriction through Orco knockout. Wildtype Dahomey females (‘control’) or females lacking the general olfactory receptor Orco (‘orco¹’) were kept in isolation or in a group with three Dahomey non-focal females. C Tactile/gustatory restriction. Focal females were housed in a standard vial (‘control’) or in a vial with a transparent, perforated divide (‘divided’). For the divided group treatment, focal females were physically separated from the three non-focals by the divide. D Visual restriction. Wildtype females held under standard light conditions (‘control’), wildtype females held in darkness (‘dark’) and white females (‘white’) were kept in isolation or exposed to three wildtype non-focal females. Fecundity was measured as the number of eggs laid in the 24-h period following mating. Boxplots as in Fig. 1. Statistical significance values between box pairs were derived from post hoc testing of models
