The European praying mantis was long a rarity in Germany. This summer, more than 15,000 sightings have been reported since early July, according to NABU.
Citizen photographs are unusually reliable for this species because its body shape and folded forelegs are distinctive.
Two expansion corridors
The species was once concentrated around the Kaiserstuhl in the southwest. It is now found much farther north along the Rhine, while a separate population has expanded between Berlin and Thuringia.
Repeated sightings in Lower Saxony and Saarland suggest that the change is not just a handful of accidental records.
Warmth determines reproduction
The eggs develop in protective cases and need sufficient warmth. Longer hot periods and milder cold seasons improve the chances of successful reproduction.
NABU experts therefore identify climate change as a central factor in the species’ expansion.
No threat to people, but an ecological signal
Praying mantises are harmless to humans. Their importance here lies less in the insect itself than in what its range shift reveals about changing habitat conditions.
A heat-loving species becoming established in regions that were once too cold makes long-term warming visible in everyday nature.
Citizen science gains value
Large numbers of verified sightings can complement formal field surveys and reveal patterns over time.
For conservation policy, the challenge is to understand not only which species arrive, but how whole ecosystems are reorganised as temperatures change.
The broader question
The headline number does not tell the whole story. Regional, sectoral and household effects can differ sharply, which is why the next data and policy decisions will matter as much as the first announcement.
For ZEITUNG.IO, the key test is whether the development remains temporary or becomes a structural shift. We will update the article as primary data and official decisions provide a clearer picture.
