... to celestial cues during tethered flight and can disperse more than 10 km under field conditions. However, we still do not understand how spectral components of celestial cues and pauses in flight impact heading direction in flies. To assess individual heading, we began by testing flies in a rotating tether...

Our study highlights how spatially and temporally distinct changes in wing shape can contribute to agile fluidic locomotion. Variation in flight behaviour could ostensibly arise through wing shape changes at any interval...

We highlight the importance of considering individual-level variation in social-level studies...

We also discuss how tracheal compression can serve as an additional mechanism for achieving advection in tracheal systems. Together, these patterns suggest that the possession of air sacs has both benefits...

Gagliardi ABSTRACT Foraging insects fly over long distances through complex aerial environments, and many can maintain constant ground speeds in wind, allowing them to gauge flight distance. Although insects encounter winds from all directions in the wild...

... observations showed that T. tricolor predominantly used two species for roosting, Heliconia imbricata and Calathea lutea , but they preferred roosting in the former. The main difference between these two plant species was the length of the leaf's apex (longer in H. imbricata ). Experiments in a flight cage...

In response, H. fusca deviated from the path predicted by pure proportional navigation, but in many cases still eventually contacted the target. We show that such flight deviations can be explained as the output of two competing...

We used the variable field cricket, Gryllus lineaticeps , which exhibits a wing dimorphism that mediates two distinct life-history strategies during early adulthood. Long-winged individuals invest in flight musculature and are typically flight capable, whereas...
