Theory suggests that male fitness generally increases steadily with mating rate, while one or
a few matings are sufficient for females to maximize their reproductive success. Contrary to …

Sexual size dimorphism (SSD) is common in both plants and animals, and current evidence
suggests that it reflects the adaptation of males and females to their different reproductive …

Nuptial feeding encompasses any form of nutrient transfer from the male to the female
during or directly after courtship and/or copulation. In insects, nuptial gifts may take the form …

Trait-based analyses explaining the different responses of species and communities to
environmental changes are increasing in frequency. European butterflies are an indicator …

Empirical and experimental studies reporting the probability that some females remain
unmated in field populations of insects (defined herein as mating failures) are reviewed in …

Many female insects receive material during mating, referred to as “nuptial gifts,” that may
increase the female's resource budget. This investigation examines how nuptial gifts …

Globally increasing temperatures may strongly affect insect herbivore performance, as their
growth and development is directly linked to ambient temperature as well as host‐plant …

Caterpillars have a great capacity for rapid weight gain, but to reap the benefits of this
capacity, larvae must be able to survive in a hostile environment and emerge as adults at the …

1. Effects of larval reserves and nutrients received as adults on fecundity and lifespan in
female Danaus plexippus (the Monarch Butterfly) were measured to determine the relative …

1. The ability of males to remate repeatedly has a dramatic effect on their lifetime
reproductive success. Moreover, nutrients transferred to females during copulation increase …
