Some #insects support passive #breathing via tracheae through #active #respiratorymovements, nsmed #convectiveventilation. Muscle contractions cause motions that e.g. dilate the #spiracles, allowing more efficient #gasexchange. The same time, the process also serves #thermoregulation. My example, the #robberfly #Tolmerus #cingulatus, demonstrates this #behavior.

Late.
But I bring you not just another great fact. Not just another bumblebee.
But a big ass dollop of the brightest yellow goodness to light up your evening after a day of resistance.
Tell me you were resisting.
You oughta!

Basic bee facts every day at 3pm.

#bees consume large amounts of oxygen but don’t breathe through noses or mouths.
Instead they draw oxygen in through holes along their bodies called #spiracles and deliver it directly to tissue and muscles.

Some species of sharks have a spiracle that allows them to pull water into their respiratory system while at rest.
