Social insect queen pheromones can be interpreted as the queen's means of sterilizing her workers, or as an honest signal of queen presence that benefits both parties. Co-mapping worker reproduces behaviour and queen cuticular hydrocarbon (CH) composition and quantity on a phytogeny of 21 stingless bee species showed that there are no associations between these traits. Furthermore, three species that have independently evoked facultative worker sterility are unexceptional in their queen CH. Combined, our analysis suggests that the action of stingless bee queen CHs are best interpreted as a signal of queen presence and not as a chemical contraceptive.
