No Sweat

Aug 1, 2011

Gotta love those dragonflies in the family Libellulidae.

The Thunderbirds of the insect world, they perform amazing aerial maneuvers as they skim over water, catching mosquitoes, knats, flies and other undesirables on the wing.

But oh--occasionally they nail a pollinator.

A red flame skimmer (Libellula saturata) skimmed over our fish pond and pool last Saturday and picked on the pollinators. Well, at least one pollinator.

It grabbed a female sweat bee, of the genus Halictus, probably H. tripartitus (as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis).

Yes, they can even identify a mangled sweat bee in the mouth of a dragonfly.

No sweat.

And no sweat bee.
