Theory predicts that because costs constrain female sexual signaling, females are expected to have a low signaling effort that is increased with passing time until mating is secured. This pattern of signaling is expected to result from females balancing the costs associated with a higher than optimal signaling effort and those costs associated with a low signaling effort that increase the likelihood of delayed mating. We tested whether this prediction applies in the common glow-worm Lampyris noctiluca (Coleoptera, Lampyridae), a capital breeding species in which females glow at night to attract males. Contrary to predictions, we found that the duration of female sexual signaling significantly decreased with time. Moreover, when females experienced multiple light/dark cycles within 24 h, both signaling duration and intensity significantly decreased. These results imply that females attempt to signal as much as possible at first, with the decrease in signaling duration and intensity likely being due to female resource depletion. Because in capital breeding females the costs of a delayed mating are likely greater than the costs of sexual signaling, females should mate as soon as possible and thus always invest into signaling as much as possible.

Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish
Sbragaglia, Valerio; Gliese, Catalina; Bierbach, David; Honsey, Andrew E.; Uusi-Heikkilä, Silva; Arlinghaus, Robert (Wiley-Blackwell Publishing Ltd., 2019)The role of sexual selection in the context of harvest‐induced evolution is poorly understood. However, elevated and trait‐selective harvesting of wild populations may change sexually selected traits, which in turn can ... -
Condition-dependence of male sexual signalling in the drumming wolf spider Hygrolycosa rubrofasciata
Ahtiainen, Jari J. (Jyväskylän yliopisto, 2003)Jari Ahtiaisen väitöskirjatyön tutkimusten perusteella voidaan todeta, että H. rubrofasciata susihämähäkkinaaraat voivat käyttää koiraan seksuaalista kuntoa mittana arvioidessaan koiraan fenotyyppistä ja geneettistä laatua. ... -
The balance model of honest sexual signaling
Fromhage, Lutz; Henshaw, Jonathan M. (Wiley-Blackwell, 2022)Costly signalling theory is based on the idea that individuals may signal their quality to potential mates and that the signal's costliness plays a crucial role in maintaining information content (‘honesty’) over evolutionary ... -
The signal detection problem of aposematic prey revisited : integrating prior social and personal experience
Hämäläinen, Liisa; Thorogood, Rose (The Royal Society Publishing, 2020)Ever since Alfred R. Wallace suggested brightly coloured, toxic insects warn predators about their unprofitability, evolutionary biologists have searched for an explanation of how these aposematic prey evolve and are ... -
Sex-specific assumptions and their importance in models of sexual selection
de Vries, Charlotte; Lehtonen, Jussi (Elsevier BV, 2023)Sexual selection is a field coloured by tension and contrasting views. One contested claim is the causal link from the definition of the sexes (anisogamy) to divergent selection on the sexes. Does theory truly engage with ...
