Giant Asian Mantis Invasion Europe: Journal Study Confirms
New evidence from Journal of Orthoptera Research verifies Hierodula mantises as invasive across Europe. Discover spread, impacts, citizen science, and ecology…
www.academicjobs.comHere are the latest credible updates on harmful mantis species in Europe.
- Two Asian mantis species, Hierodula tenuidentata (Giant Asian Mantis) and Hierodula patellifera, have been formally recognized as Invasive Alien Species in Europe, with populations spreading beyond their historic introductions and increasing across the Mediterranean and continental regions. These designations reflect concerns about their impacts on native insects, pollinators, and broader food webs.[2][3][5][7]
- The expansion appears to be driven by climate suitability and broad prey ranges, enabling northward and inland movement from initial southern introductions. Recent studies and press releases emphasize elevated predation on native mantises and competition effects on native invertebrate communities.[3][8][2]
- Public-interest efforts highlight practical management tips, notably winter removal of oothecae (egg cases) to curb reproduction, though accurate species identification is essential to avoid harming native mantis populations.[5][2]
- Geographic notes from multiple sources indicate established populations in parts of Italy (Veneto, Sicily and potentially other regions), with reports of spread to France and findings of northward movement into several European countries, underscoring a continent-wide invasion trend.[6][2][3]
Illustrative example
- Visual summary: two Asian mantis species (Hierodula tenuidentata and H. patellifera) have invaded Europe, outcompeting natives and altering predator-prey dynamics; winter egg-case removal is suggested as a targeted control measure, while accurate species ID is crucial to protect native mantises.[2][5]
