From rearing to spreading: ecological constraints and distribution patterns of Carausius morosus (Sinéty, 1901) (Phasmatodea: Lonchodidae)

Abstract

Based on available data on the occurrence of Carausius morosus (Sinéty, 1901) and its subsequent graphical processing into map outputs, it was possible to identify basic ecological requirements responsible for its spread beyond its original Indian range. Despite considerable adaptability, certain factors significantly limit the spread of the stick insect in several regions and currently represent insurmountable barriers to its further advance. The species shows a clear link to warm, humid areas with subtropical and tropical climates, providing a framework for understanding its possible future dispersal.
