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.

The #robberfly #Tolmerus #cingulatus is native to the Palearctic and prefers dry #habitats. #Adults #prey on other insects, killing their prey with #neurotoxins, predigest via #enzymes. Larvae are soil predators. R. Mitchell (2024) presents a #genome (280,000 megabases) for the #DarwinTreeofLife. See also my science blog article (2024).
