- ... In response to competition, males should invest in premating traits (i.e., courtship) to enhance their mating success or in postmating traits (i.e., sperm) to increase fertilization success. We show instead that in the presence of a rival, spiders courting females with food gifts reduce both, investment in gifts and sperm.

In eusocial insects, nest mate recognition is based on cuticular hydrocarbons and allows colony members to reject competitors and parasites. The study of recognition cues in subsocial species can provide insights into evolutionary pathways leading to permanent ...
