Highlights
- We investigated sexual selection on male and female morphology in a lygaeid bug.
- We varied the level of choice available to males and females during mating trials.
- We found significant sexual selection on male and female morphology.
- However we found no effect of choice paradigm on the strength of selection.
- The mechanism of mate choice in this species may limit comparison between options.
Mate choice has long been appreciated as a key component of sexual selection. However, how we measure mate choice, both in the field and in the laboratory, remains problematic. Mating preferences may be tested using either no-choice or choice tests, but explicit comparisons between these two experimental paradigms remain limited. It has been suggested that preferences may be stronger in choice tests as they allow simultaneous comparison, and some studies have indeed found stronger mating …
