Each day they eat hundreds of insects each as they patrol her yard on a hot August day.
Unfortunately, they did not snag the one mosquito who carried Eastern Equine Encephalitis virus to my daughter’s four year old horse, not so long ago moved down from South Dakota.
The horse didn’t make it. The dragonflies carry on, and I can only think that, as bad as West Nile and so many other mosquito-borne diseases have become, they’d be even worse without the eco-services of the dragonflies.
Too bad the bats are not able to help so much with this task as they once did. We sure could use them in the game.
CAPTION: the Lumix LX7 has a disappointing 3x optical zoom, but the 7x digital zoom used to take this shot of a small coastal dragonfly perched on the wisteria arbor is pretty impressive for its clarity and freedom from the usual shortcomings of digital magnification. Click to enlarge.
