Hormonal pleiotropy helps maintain queen signal honesty in a highly eusocial wasp

Abstract In insect societies, both queens and workers produce chemicals that reliably signal caste membership and reproductive status. The mechanisms that help to maintain the honesty of such queen and fertility signals, however, remain poorly studied. Here we test if queen signal honesty could be b...
