The Edwards Glassy Wing, also known as the Glassy-winged Sharpshooter (GWSS), is an invasive insect that poses a significant risk to various plant species. Originally native to the southeastern United States and northeastern Mexico, it was accidentally introduced to California in the late 1980s, most likely through egg masses on ornamental or agricultural plant foliage source.
This pest feeds on the xylem fluid of a large number of plants and has a wide host range, including citrus plants source. Due to its feeding habits and reproduction capabilities, GWSS has been causing significant damage to vineyards and other agricultural crops by spreading Pierce’s disease. As a result, a statewide management program was implemented in California to counter the threat posed by GWSS and the bacterial diseases it transmits source.

|---|---|---|
| Color Patterns | Bright | Muted |
| Hair/Fuzz | Present | Absent |
| Display | Not prominent | Glassy wing |
Reproduction and Mating
In terms of reproduction and mating, the Edwards Glassy Wing moth follows a standard life cycle pattern:
- Mating: Adult moths engage in a mating ritual that may involve wing displays and pheromones.
- Eggs: Female moths lay eggs on appropriate host plants.
- Larvae: The eggs hatch, producing larvae that feed on the host plant and eventually pupate.
- Adult Moths: The pupae metamorphose into adult moths, starting the cycle anew.
The specific behaviors and strategies of the Edwards Glassy Wing moth during mating and reproduction have yet to be fully understood, warranting further study by entomologists.
