Spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae), is an invasive, phloem-feeding planthopper that feeds on over 100 species of host plants. It feeds voraciously across a wide range of hosts, including grapes and other specialty crops, as well as on plants and trees in urban, suburban, managed and natural forested areas. Likely because of its need to feed so heavily on plant sap, it has proven challenging to rear this pest in captivity such that its fitness is comparable of that of wild populations of spotted lanternfly. In order to better understand the fitness of wild spotted lanternfly populations, and better understand this insect's nutrient requirements, insects were sampled bi-weekly across their life cycle (from May to November) at each of nine sites in Pennsylvania in 2022 (20 insects collected per site per collection event). Live masses were recorded, and a subset of collected insects were preserved and assayed for carbohydrate, lipid, and protein levels. Adult females were also dissected to determine their reproductive development. Results will be presented showing trends in spotted lanternfly mass and nutrient status over time, as well as identify any of these measures that were associated with female reproductive development.
