Highlights•Low-amplitude signalling is a common but understudied form of
communication.•These signals can be both structurally and functionally distinct from loud …

Signalling via substrate vibration represents one of the most ubiquitous and ancient modes
of insect communication. In crickets (Grylloidea) and other taxa of tympanate Ensifera …

Phonation critically depends on precise controls of laryngeal muscles in coordination with
ongoing respiration. However, the neural mechanisms governing these processes remain …

Highlights•Artificial light at night may influence key fitness-related behaviours of
animals.•Effects on mating and courtship behaviour are not well known.•We examined …

The initial process by which novel sexual signals evolve remains unclear, because rare new
variants are susceptible to loss by drift or counterselection imposed by prevailing female …

Males can produce complex sexual signals, often in different sensory modalities. The
information conveyed by multiple signals, and the degree to which multiple signals interact …

Acoustic signals used by males to attract females are among the most prominent examples
of secondary sexual traits, yet we have only limited understanding of their genetic …

Reproductive proteins are amongst the most evolutionarily divergent proteins known, and
research on genetically well‐characterized species suggests that postcopulatory sexual …

Global declines in insect abundance are of significant concern. While there is evidence that
climate change is contributing to insect declines, we know little of the direct mechanisms …

Highlights•Dynamic repeated displays are often used by courting animals.•Repetition may
function as signal validation or demonstrate cost capacities.•Stridulation in crickets is …
