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 …

It is becoming increasingly clear that the evolutionary interests of the sexes are often in
conflict when it comes to mating. Sexual encounters involving nuptial gifts, however, have …

Ensifera present an appropriate and interesting model for the study of acoustic
communication, because of their diverse signal and communication modalities, and due to …

In pipefishes and seahorses (family Syngnathidae), the males provide all postzygotic care of
offspring by brooding embryos on their ventral surfaces. In some species, this phenomenon …

Female-biased size dimorphism, in which females are larger than males, is prevalent in
many animals. Several hypotheses have been developed to explain this pattern of …

Sound production in insects is accomplished either by stridulation–the frictional rubbing of
cuticular parts–or by strigilation–the setting of drum-like cuticular membranes into oscillatory …

▪ Abstract Mate choice theory has become a major field of research in behavioral ecology.
Tree crickets provide excellent opportunities for studying the diversity and variability of mate …

We review mating-systems theory and conflict theory and apply them to the analysis of
intrasexual and intersexual conflicts. We distinguish three types of sexual interaction …

Courtship feeding in the majority of insects may influence female reproductive patterns
either directly, through effects of the gift material, or indirectly, through correlated effects of …

The spermatophore transferred by male decorated crickets (Gryllodes sigillatus) at mating
includes a large gelatinous spermatophylax that the female consumes after copulation …
