Early predator detection is a key component of the predator-prey arms race and has driven the evolution of multiple animal hearing systems. Katydids (Insecta) have sophisticated ears, each consisting of paired tympana on each foreleg that receive sou...

Insects are the most abundant and diverse class of animals on the planet. One explanation for their success is their extraordinary ability to successfully consume a wide range of foods. Like all heterotrophic organisms, insects need to acquire vital... Read More about Extracellular nutrient digestion and absorption in the insect gut.

Verlinden (Ed.), Insect Epigenetics (167-285). London: Academic Press. https://doi.org/10.1016/bs.aiip.2017.06.002

Locusts are grasshoppers (Orthoptera: Acrididae) that are characterised by their capacity for extreme population density-dependent polyphenism, transforming between a cryptic solitarious phase that avoids other locusts, and a swarming gregarious phas...

Born to win or bred to lose: aggressive and submissive behavioural profiles in crickets (2016)
Journal Article
Rose, J., Cullen, D. A., Simpson, S. J., & Stevenson, P. A. (2017). Born to win or bred to lose: aggressive and submissive behavioural profiles in crickets. Animal behaviour, 123, 441-450. https://doi.org/10.1016/j.anbehav.2016.11.021

Aggression between conspecific males is widespread in the animal kingdom, as is the fact that some individuals are far more aggressive than others. Consistent interindividual differences in behavioural profiles are generally regarded as a hallmark fo...

Take-off speed in jumping mantises depends on body size and a power-limited mechanism (2016)
Journal Article
Sutton, G. P., Doroshenko, M., Cullen, D. A., & Burrows, M. (2016). Take-off speed in jumping mantises depends on body size and a power-limited mechanism. The journal of experimental biology, 219(14), 2127-2136. https://doi.org/10.1242/jeb.133728

Many insects such as fleas, froghoppers and grasshoppers use a catapult mechanism to jump, and a direct consequence of this is that their take-off velocities are independent of their mass. In contrast, insects such as mantises, caddis flies and bush... Read More about Take-off speed in jumping mantises depends on body size and a power-limited mechanism.

Pollen feeding proteomics: Salivary proteins of the passion flower butterfly, Heliconius melpomene (2015)

While most adult Lepidoptera use flower nectar as their primary food source, butterflies in the genus Heliconius have evolved the novel ability to acquire amino acids from consuming pollen. Heliconius butterflies collect pollen on their proboscis, mo... Read More about Pollen feeding proteomics: Salivary proteins of the passion flower butterfly, Heliconius melpomene.

Mantises exchange angular momentum between three rotating body parts to jump precisely to targets (2015)
Journal Article

Flightless animals have evolved diverse mechanisms to control their movements in air, whether falling with gravity or propelling against it. Many insects jump as a primary mode of locomotion and must therefore precisely control the large torques gene...

Desert Locusts can change reversibly between solitarious and gregarious phases, which differ considerably in behaviour, morphology and physiology. The two phases show many behavioural differences including both overall levels of activity and the degr...

Locusts exhibit a behavioural syndrome known as 'behavioural phase polyphenism', in which a number of behavioural traits change markedly in response to local population density. 'Solitarious' phase individuals, which are typical of low-density popula... Read More about Optimizing multivariate behavioural syndrome models in locusts using automated video tracking.
