Gustatory sensitivity to amino acids in bumblebee mouthparts Open
Bees rely on amino acids from nectar and pollen for essential physiological functions. While nectar typically contains low (less than 1 mM) amino acid concentrations, levels in pollen are higher but variable (10–200 mM). Behavioural studie…

Gravity and active acceleration limit the ability of killer flies ( <i>Coenosia attenuata</i> ) to steer towards prey when attacking from above Open
Insects that predate aerially usually contrast prey against the sky and attack upwards. However, killer flies (Coenosia attenuata) can attack prey flying below them, performing what we term ‘aerial dives'. During these dives, killer flies …
Prey speed influences the speed and structure of the raptorial strike of a ‘sit-and-wait’ predator Open
Predators must often employ flexible strategies to capture prey. Particular attention has been given to the strategies of visual predators that actively pursue their prey, but sit-and-wait predators have been largely overlooked, their stra…
Interception by two predatory fly species is explained by a proportional navigation feedback controller Open
When aiming to capture a fast-moving target, animals can follow it until they catch up, or try to intercept it. In principle, interception is the more complicated strategy, but also more energy efficient. To study whether simple feedback c…
Conservative whole‐organ scaling contrasts with highly labile suborgan scaling differences among compound eyes of closely related <i>Formica</i> ants Open
Static allometries determine how organ size scales in relation to body mass. The extent to which these allometric relationships are free to evolve, and how they differ among closely related species, has been debated extensively and remains…
