Length: typically 3.2 - 3.3 mm
Two common and widespread Nearctic leafhoppers are Agalliota constricta and A. quadripunctata. They look very much alike, but A. constricta is narrower.
Shaw (1976) reported on the sounds produced by Agalliota constricta, and behaviors associated with sound production. Like Cicadas, leafhoppers produce sounds using tymbalsvibrating membranes located on the abdomen.
When Shaw placed a male and a female Agalliota constricta into an observation chamber, usually the male emitted some calls, which were sometimes answered by the female. If the female did answer, the two soon began to alternate the calls. The female participation in the alternation of the calls served to alert the male that a sexually receptive female was nearby, and mating behavior usually followed. The sound pattern of the calls is different for each species, and thus one function of the calling is to assure both the male and the female that the other calling individual is indeed of the same species.
Researchers at the University of Mississippi reported that Agalliota constricta was one of the more common species feeding in Ole Miss's famed Marijuana garden (the crop is grown for research purposes and largely funded by the U.S. government). The researchers did not mention any erratic behavior on the part of the dining leafhoppers.
