#robberfly — Public Fediverse posts

An Asilidae aka "Robber Fly" enjoys a meal of a fly in the Panamint Valley, California. April 2021 Note the proboscis stabbed into the back of the fly. It injects a neurotoxin and digestive enzymes and slups up its meal. #panamint #robberfly #nature #brutal #fly #bugs #desert #macro #cvvhrn #r2508

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.

It's the heart of summer. All the insects are here. (IDs with each picture.) #insects #dragonfly #robberfly #honeybee #flowers #onionflowers #teaselflowers #dogbaneflowers #nature #photography #naturephography
