Abstract:

Invasive species pose significant ecological and economic threats, and this is often linked to their ability to reproduce quickly. Understanding factors that influence mating dynamics in invasive species yields insight into population growth and guides interventions for invasive species management. The spotted lanternfly (Lycorma delicatula) is an invasive planthopper that was discovered in the USA in 2014, and it’s harmful to ecosystems and the economy due to its feeding habits. However, the mating dynamics of this species remain unclear, limiting development of management tools. To address this gap, we collected females engaged in courtship during Fall 2024 and evaluated morphological and ecological correlates of female attractiveness, using the number of males courting each female as a proxy for attractiveness. With these data, we assess how female phenotype, mating history, and environmental conditions are associated with patterns of male courtship and female attractiveness in the spotted lanternfly. The results of this study illuminate the mating ecology of the spotted lanternfly, contributing to broader efforts to predict population growth patterns and invasion dynamics.
