Perched and powerful.
Robber flies are powerful predators that ambush other insects in mid-air, using a stout proboscis to inject paralyzing, digestive saliva.

In the macro world , every second is filled with something thrilling & intractive moments between the species.Small creatures often create the most explosive moments in nature.

The robber fly #Tolmerus #cingulatus (#Asilidae, #Diptera) can frequently be observed in #Berlin. Its strength lies not in a long, sustained, and energy-efficient flight, but in the opposite. As an #ambushpredator, the robber fly observes its surroundings from a prominent position. Suitable #prey are usually flying #insects, which the robber fly captures in a rapid, targeted, and precise sprint flight, #efficiently grasping them with spiny leg segments and spiny, forward-facing #bristles.
This requires strength and precision and is therefore particularly #energy-intensive. While resting, in this case perched on my sun-exposed #windowsill, it supported more efficient gas exchange through #convective #ventilation. At the same time, the #thermoregulation effect prevented its body from #overheating.
#breathingmovements, known as convective ventilation, actively support gas exchange, for example, by opening the #spiracles further. Such breathing movements are necessary and helpful when an insect has to perform a particularly #energeticallydemanding task. The resulting accelerated air exchange also achieves thermoregulation, which prevents the insect from being harmed by excessive heat, what the fly had to deal with in my windowsill.
The authors E. Gefen (2021) studied detailed aspects of the complex #motoractivity connected with insect gas exchange patterns, which also includes central and peripheral #chemoreception.

Taking photos of butterflies when I noticed this fly nearby - could it be a Kite-tailed Robberfly; ID help welcomed

Happy #FlyFriday
This fast powerful cuddly-looking mimic a Bumblee #Robberfly with click #beetle prey - depends on deadwood & seems to hunt most in sunshine.

おはようございます🌥️
さまざまな昆虫が姿を現し活発に行動し始めています
今朝は自然体験林で何者かにより顔を数か所刺されました
季節ですねぇ…💦
