New paper on seeing in air and water with compound eyes!

The problem: physics

The solution: physics

Elegantly described with the dream team @tannermierow.bsky.social and @alexkingston.bsky.social

Pixie robber flies are merciless predators, successfully intercepting perched victims, & in their recent JEB paper, @rossonisergio.bsky.social &co reveal that the insects use their motion relative to the prey to determine the victim's size and how far off they are

Some robber flies hunt resting prey and judge their distance well despite limited vision. We show their looping flights help them estimate this via motion parallax. A neat example of active vision making up for optical limitations! ๐Ÿ‘€๐Ÿชฐ

Predation via motion parallax in one of two gleaning insects A predator's survival is highly dependent on correctly deciding whether to attack potential prey. Pursuit predators, for example, can estimate the size of a moving target from the ratio between its an...

Predators must estimate the size of a potential prey. Size of a moving target is assessed by angular speed/size, rules that not apply for stationary prey. Unlike damselflies, pixie robber flies use motion parallax to infer prey size. @rossonisergio.bsky.social journals.biologists.com/jeb/article/...

Netcasting spiders hurl a stretchy net to capture prey, a net that can double in size during full extension. A study explores how the silk achieves such impressive elasticity without sacrificing strength. In PNAS: https://ow.ly/qRYu50Y5z8x

Gustatory sensitivity to amino acids in bumblebee mouthparts | Royal Society Open Science 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 (10โ€“200 mM). Behavioural studies suggest ...

๐Ÿšจ Our study from @bethbees.bsky.social lab is out in @royalsocietypublishing.org . We show that bumblebees taste some amino acids (valine), but not others (lysine). Bees might choose flowers not just by how sweet they taste! #bees ๐Ÿ #taste ๐Ÿ‘… #pollen #nectar ๐ŸŒบ #protein ๐Ÿฅฉ
