Length: typically 3.2 - 3.3 mm
Right: Agalliota quadripunctata on a plant stem, taking a break from feeding, its beak-like mouthparts tucked away under the head. Note the sharp carina or ridge along the top front edge of the head, typical of this subfamily.
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.
A number of writers have noted that males of Agalliota quadripunctata are rare, and that the vast majority of collected specimens are female. Black and Oman (1947) verified in the laboratory that this species reproduces through parthenogenesis. They commented, "The presence of males in some populations of quadripunctata may indicate that at times the species does reproduce bisexually. On the other hand, such males may be nonfunctional."
Left: The face of an Agalliota leafhopper. The genus name Agallia has also been applied to this group. Nomina Insecta Nearctica uses Agalliota, a name that separates the New World species from related Old World species.
