Singapore, being land-scarce and lacking in natural resources, has invested immensely in food security. In a new era brought about by the COVID-19 pandemic and anthropogenic climate change, global supply chains can be disrupted easily and the ability to produce food locally becomes even more critical. More recently, there has been greater interest...
Article
In India, the cricket subfamily Eneopterinae is represented by two known genera, Xenogryllus Bolívar, 1890 and Indigryllus Robillard & Jaiswara, 2019. The latter was recently described and is known from a single species I. kudremu Robillard & Jaiswara, 2019 from Karnataka, India. The species was known exclusively from its morphological features and...
Article
Mate advertisement signals can vary in their variability, with some signals or signal components being highly stereotyped and others highly variable. One hypothesis for differences in variability suggests that receivers provide stabilizing selection for signal components important for mate recognition, resulting in low variability, while also provi...
Article
From the eastern parts of Sabah, four new species of crickets are described, two of which are from the subfamily Landrevinae and two from the subfamily Podoscirtinae: Duolandrevus (Duolandrevus) nobilis sp. nov. and Odontogryllodes spinifer sp. nov.; and Brevimunda trilineata sp. nov. and Varitrella (Cantotrella) tabin sp. nov., respectively.

Article
Individual fitness can be boosted by behavioural strategies that maximise mate-finding probability while minimising predation risk. Animals that use acoustics to find mates may benefit from using both stationary calling and active exploration, but these also expose them to different types of predators. Studying calling and searching behaviours conc...
Article
Circadian rhythms are endogenously generated and self-sustaining oscillations that occur at a 24 hours scale and are ubiquitous among animals. Animals rely on their circadian clocks to anticipate cyclical external environmental oscillations to find mates and reproduce, among other activities. Hence, animals that sing to attract mates can modulate t...
Article
The Lebinthini crickets are distributed in Southeast Asia, Western Pacific and tropical South America. They represent more than half of the described species in the subfamily Eneopterinae. These crickets are morphologically and behaviorally diverse, varying in body size, wing morphology (ranging from brachypterous to fully winged) and acoustic sign...

Article
Full-text available
The receiver sensory system plays a crucial role in the evolution of new communication signals in insects. Among acoustic communicating crickets, the tribe Lebinthini (Eneopterinae) has evolved a unique communication system in that males produce exceptionally high-frequency calls and females respond with vibratory signals to guide males towards the...
Presentation
Adaptive radiations are major drivers of diversification which are triggered by novel ecological opportunities or opening of new niches due to innovations of variable traits, including key features of communication systems. For example, groups of animals that communicate using a particular type of signal that is not used by other species or not det...

In field crickets (Gryllus bimaculatus), the brain receives auditory input from two ascending neurons; AN1 is sharply tuned to the low-frequency (5 kHz) calling song of the males and controls positive phonotaxis, whereas AN2 triggers negative phonotaxis and is tuned to high- frequency sounds like predatory bat calls. In one group of crickets (Eneop...
