Abstract

Multiple mating by females is a subject of considerable controversy. In some species, however, females appear to mate only once, and the potential costs and benefits of this behavior are equally intriguing. When male mating success is highly skewed, monandrous females potentially risk mating with a sperm depleted male. In lek-breeding species, a male may gain up to 80% of available matings, yet few studies have explored whether these highly successful males suffer sperm depletion. These points are investigated in a series of laboratory experiments on the lekking sandfly, Lutzomyia longipalpis. It is shown that females may actively reject males prior to and after genital contact and that mate..
