Inter- and intra-population variability in spotted lanternfly egg mass hatch timing across the invaded range in the United States

Spotted lanternfly is an invasive tree hopper that was first found in Pennsylvania in 2014 and has sense spread to multiple states. This insect has a winter egg diapause and as it spreads will be exposed to novel climatic regimes. The spotted lanternfly's ability to establish reproducing populations in the new areas will in part depend on its adaptability and plasticity in egg hatch traits. For example, in areas where the growing seasons are shorter there would be an advantage of being able to hatch as early as conditions are favorable for nymphal development. This study looked at what variation in egg hatch traits is present across the invaded range in the United States, both within and between populations, to better understand spotted lanternfly's ability to invade novel habitats.
