The common name used here is of my invention. I do not know why Clemens chose the name falsarius for this species, but I assume it was due to the superficial resemblance to the Grapeleaf Skeletonizer Moth, Harrisina americana, or to another Acoloithus. I Thank James Adams for identifying the moth.

I had just gone through a dry spell of two weeks, during which no new species were found, when, after a severe rainstorn and during a stiff breeze that ruffled the sheet by the black light, I saw a tiny pair of these moths in copulation. In the purplish glow of the blacklight I was not certain, using just the naked eye, if these were in fact moths. A hand lens in the Moth Lounge quickly decided that point. The larger Grapeleaf Skeletonizer Moth has a wingspan, according to Covell, of between 1.8-2.8 cm., whereas in my virtually identical pair of A. falsarius, the wingspan was 1.5 cm. Notice that A. falsarius has an incomplete orange collar, and coarser, comb-like antennae. It never holds its wings in the oblique posture of H. americana. The hind wings are fairly translucent. They were quite tame on the photo table.

Much larger still (wingspan 2.9-3.7 cm) is the Yellow-collared Scapemoth, Cissips fulvicollis. Even larger (wingspan 4-5 cm) is the Virginia Ctenucha Moth, Ctenucha virginica. Nature often repeats successful color combinations.
