European Mantid - Montana Field Guide
Montana Field Guide contains a wealth of information about Montana's diverse species.
fieldguide.mt.govHere’s a concise update on the latest in Europe regarding harmful mantis species.
-
What’s new: Two large Asian mantis species have been formally identified as invasive alien species in Europe, with populations expanding notably in the Mediterranean and neighboring regions. This status change reflects growing concerns about their impacts on native biodiversity and ecosystems.[3][4]
-
Why it matters: These species can outcompete native mantids, prey on a range of native invertebrates including pollinators, and occasionally affect small vertebrates. Public participation for monitoring and potential control is being encouraged in some studies.[4][5]
-
Geographic spread: Reports point to established presences in parts of Italy and France, with northerly/earlier records in other European countries; observers and citizen scientists are urged to help track sightings and ootheca (egg cases) during winter when they’re easier to spot.[6][4]
-
How authorities are responding: Researchers are calling for assessments and public vigilance, including guidance on safe egg-case removal when appropriate and under expert supervision to avoid harming native mantises.[4][6]
-
Context from coverage: Multiple outlets have reported similar findings, emphasizing the invasive status and the potential ecological consequences across Europe. If you’re in New Jersey or the U.S. East Coast, this may be less immediately relevant, but the situation illustrates how invasive arthropods can rapidly alter ecosystems under climate and mobility changes.[8][3]
If you’d like, I can pull a few direct sources and summarize key findings from the latest studies, or focus on the specific countries in Europe where monitoring is most active.
