The colours of insects function in intraspecific communication such as sexual signalling,
interspecific communication such as protection from predators, and in physiological …

In some species, males use weapons to harm females, increasing their short-term fitness.
Here we show that females can use genital adaptations against males. Females of the …

Sexual selection can improve population fitness and purge deleterious mutation from the
gene pool by promoting condition‐dependent mate selection. One ecological factor that …

Female mimicry by males is a widespread phenomenon in several taxa and may be
involved in aggression avoidance or facilitated access to resources. In early developmental …

Highlights•X. erythroneurum changes colour from yellow to red during ontogeny.•Red males
are more conspicuous and in better condition than yellow males.•Females do not prefer …

The prevalence and intensity of parasitism can have different fitness costs between sexes,
and across species and developmental stages. This variation could arise because of …

Several insect groups exhibit the phenomenon of cannibalism, preying upon individuals of
the same species. Cannibalism is an intriguing behavior but often poorly understood …

We investigated the significance of sexual maturity, courtship behaviour and mating refusals
in an aphidophagous ladybird, Coccinella transversalis Fabricius using four mating …

Ontogenetic habitat shifts are predicted to increase the fitness and survival of individuals by
allowing effective utilization of spatially distributed resources. Evidence supports nutritional …

Host–parasite interactions are impacted by climate, which may result in variation of
parasitism across landscapes and time. Understanding how parasitism varies across these …
