Learning to Look Closer #2: Just Outside the Window
My nephew was standing at the window this morning when a tiny robber fly flew up to the glass. For a minute, it almost seemed like they were entertaining each other. It would fly away, then come back again, hovering just long enough to catch his attention. Every time it returned, he lit up a little more. Then it landed. I grabbed my phone, quietly walked over, and snapped a single picture through the window. One click. That was all I got. As soon as the photo was taken, it lifted off […]https://destinylaharris.wordpress.com/2026/07/22/learning-to-look-closer-2-just-outside-the-window/

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.
Please watch my YouTube video; my channel needs more views.

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).

Love these guys :ablobcatnod:
Had one riding shotgun on my right shoulder while mowing a few days ago. Would like to believe they're going to pounce on any pesky fly that comes near us😆

Robber Flies. First time I've ever spotted the Bumble Bee variety in the wild :ablobcool:

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. Then it slups up its meal. #panamint #robberfly #nature #brutal #fly #bugs #desert #macro #macromonday

Caution: The last photo shows an insect killing another insect. You've been warned. I went for a short walk thru a meadow today and forgot to bring my cane. Perhaps I will try this again tomorrow. IDs with ALT descriptions. #insects #insectphotography #butterflies #robberfly #nature #HoosierMast
