Spotted Lanternfly (SLF) is an invasive plant hopper from China. It was first detected in the United States in 2014 and spread to New Jersey in 2018. As a polyphagous species with over 103 host plants, SLF possess a substantial threat to both the agricultural and forestry industries through their gregarious feeding on the plants phloem. SLF host plant range is believed to be at its highest in the early instars and begins to narrow with development. Identifying developmental differences between host plants and cohorts can help with understanding potential threats throughout the season. This study sought to examine development across all four juvenile stages of SLF on four known host plants. These hosts included tree of heaven, cultivated grape, black walnut, and red maple. This study showed differences in survivorship between both host plants and life stage.
