A team of Italian researchers conducted a groundbreaking study on the impact of praying mantis species on the European ecosystem, particularly focusing on two species identified as invasive. These species, Hierodula tenuidentata and Hierodula patellifera, have shown alarming patterns of reproduction that contribute to their designation as "exotic invasive species," as reported in the Journal of Orthoptera Research. The study, led by Roberto Battiston from the G. Zannato Museum of Archaeology and Natural Sciences in Italy, marks a significant milestone in understanding the ecological threats posed by non-native species.

The formal recognition of these mantis species as invasive occurred in February 2026, emphasizing their rapid establishment in Europe over the past decade, originating from Asia and initially spreading from India to regions in Greece. The implications of their presence are concerning, as they pose increasing risks to local biodiversity and ecosystems. The invasive nature of these species raises questions about predation pressure, competition with native insects, and overall ecosystem balance, which could have cascading effects on both plant and animal life.

Battiston stresses the importance of addressing the ecological consequences of these invasive mantis species promptly. The study reflects the necessity for ongoing research and monitoring of invasive species, considering their adaptability and reproductive capacity. Understanding the dynamics of such species not only helps in managing current populations but also in implementing preventive measures to avoid similar situations in the future, ensuring the preservation of Europe’s rich biodiversity.
