Exploring behavioural plasticity in the nesting biology of Megachile sculpturalis (Hymenoptera: Megachilidae) and its role in invasion success
Journal: European Journal of Entomology
Year: 2025

The success of animal species is shaped by a combination of ecological conditions and behavioural plasticity, with the latter being particularly crucial for the spread of invasive species. Megachile sculpturalis (Apoidea: Megachilidae), an East-Asian solitary bee introduced to France and subsequently spreading across Europe and North America, provides a case study. While its distribution is well-documented, the behavioural traits driving its success remain poorly understood. Our study aimed to e
