Giant Invasive Mantises Are Taking Over Europe - SciTechDaily
These mantises are increasingly posing a threat to local biodiversity through intense predation and competition for reproduction.
scitechdaily.comHere’s a concise update on the latest news about harmful mantis species in Europe.
Key developments
- Two Asian mantis species have been identified as invasive across parts of Europe, with rising populations noted in the Mediterranean and continental regions. This status change is based on recent research and surveillance indicating their potential to disrupt native ecosystems.[3][5]
- Specifically, Hierodula tenuidentata (Giant Asian Mantis) and Hierodula patellifera (Indochina Mantis) are being documented as invasive alien species in multiple European countries, reflecting a northward and inland expansion over the last decade.[2][5][3]
- Researchers emphasize ecological risks, including predation on native species and potential competition with local mantids, as well as possible effects on pollinators and small vertebrates in affected habitats.[5][3]
Geographic patterns
- Italy has reported stable or expanding populations of these species since around 2018–2020, with records in several regions indicating established populations rather than transient introductions.[6][2]
- Other European countries, including France, Romania, Serbia, Greece, Spain, Slovenia, Albania, and Ukraine, show evidence of spread or new sightings, suggesting a broader European footprint beyond the initial introductions.[2][3][5]
What this means for monitoring and management
- The designation as invasive alien species highlights the need for citizen science involvement, reporting sightings, and monitoring programs to track range expansion and ecological impacts.[3][5]
- Local authorities and researchers are calling for assessments of biodiversity impacts, especially in Mediterranean islands and regions with endemic species, to inform potential control or mitigation strategies.[5]
Illustrative note
- A 2026 open-access study and accompanying news coverage emphasize that these mantises can outcompete natives and threaten pollinators, reinforcing the importance of early detection and public participation in monitoring efforts.[7][5]
