This will not likely be a weekly or monthly title.  Maybe annually although I do see this wasp family often enough. We’ll see. Maybe some of you would rather this is a one off.  🙂

I was chasing hover flies on our gooseneck flowers when these arrived.  They all got along okay.  I’ll post one of hoverfly later on.

Mexican Grass-carrying Wasp- Isodontia mexicana

These are not at all aggressive although touching one might be a mistake.

I was lucky and their wing iridescence shows in all these shots.

I am always amazed at the thinness of the “waist” and how the abdomen seems precariously attached to the thorax.  And also how the necessary bodily functions are carried out despite the narrowness.

They also prey on small insects in addition to supping on nectar.  The “Grass-carrying” part of the name comes from their practice of cutting pieces of grass and lining their nests inside tubular structures with it.

  1. What excellent closeups: you’ve got the technique down.

    If people can get called wasp-waisted then I guess for wasps you’ve got to narrow that down to thread-waisted.

  2. Another amazing creature with adaptations we don’t understand. Very nice images, Steve, those pretty flowers made a great background to show these wasps off.

  3. Very similar to a “mud dauber” wasp in body type, but not in nest construction. Nice images.

    • I haven’t read about their naming so am not sure if they originated there or it’s just where they were first seen. They are found in almost every U.S. state. Invasive Murder Hornets are another thing. 🙂

    I just learned that Hymenoptera comes from the Greek humenopteros, or ‘membrane-winged.’ These often show off those wings to good effect — as well as their amazing body structure.
