How long does a GWSS live? Can it survive freezing weather?
Glassy-winged sharpshooter adults begin laying egg masses from February through May. The year’s first generation matures as adults from May through August. In June through September, these adults lay the eggs that will become the year’s second generation. It is this generation that overwinters in the adult stage and then produces the next year’s offspring. The insect apparently is able to survive winter temperatures dipping as low as 20 degrees Fahrenheit. Whether our not it can withstand colder temperatures for any duration is unknown at this time.
