Additional information from Betsy:

Based on some questions in the seminar, I looked for additional information on spotted lanternfly.  The information on native range seems to vary quite a bit, including where it was found and when, and the temperature range .  I’ve included some references here for anyone interested in learning more.

From Lifecycle section of Wikipedia entry on spotted lanternfly:

Some researchers believe that a severe cold interval is required for the eggs to develop past a certain point, however this has not yet been confirmed.[11] Testing has been done to determine how overwintering affects the eggs of the species. The minimum temperature that will kill eggs was estimated by South Korean researchers to be between −12.7 and −3.4°C (9.1 and 25.9°F) on the basis of mean daily temperatures during their winter of 2009/2010.[15] This estimate contrasts with eggs having survived the much colder winter 2013/14 temperatures in Pennsylvania, United States.[16] Another study done in South Korea suggested that -25°C is about the temperature in which no eggs are hatched, while 15°C still had limited hatching, depending upon how long they were chilled and where they were kept.[17]
