Extensively used by bats in the Boston region.

Fun fact: Some moths intentionally generate sound to mess with bat sonar. Think nature's radio jammer. Many listen for sonar pulses and have structures that make similar frequencies so this is pretty accurate.
Tried to find the original artist on this, but came up dry for this specific image. However, I did find this version from six years ago that's credited to @twisteddoodles on Instagram, who it turns out is Maria Boyle, a cartoonist for New Scientist (and a scientist herself):

Now, on OP's image you can see the little "MB" in the lower right, which makes me think that Boyle re-painted the original artwork, but I can't seem to find it anywhere. I'd love to buy a print or tshirt of it or something like that!
