A bright yellow European praying mantis has captured the attention of internet users after a German wildlife enthusiast shared a photo of the insect.
But beyond the surprise factor, this unusual observation also encourages people to help scientists track where these insects appear.
What's happened?
The conversation started with a Reddit post featuring a yellow European praying mantis (Mantis religiosa), with the poster commenting that he had never seen one in Germany before, adding, "I didn't know they came in that yellow.".

In the comments, people noted both the unusual coloring and the local distribution of this species. One commenter wrote, "I'm still waiting to see it in my area. What a great find!"«
Other Reddit users also pointed to NABU, a German conservation organization that collects public reports of mantises for scientific research. One commenter noted that the organization tracks the species' spread, as well as the locations of individual insects and established populations.
Why is this important?
The yellow mantis may seem like a minor curiosity, but such observations help document changes in ecosystems. When insects begin appearing in new locations or in greater numbers, it can signal a change in local conditions.
In the discussion, participants mentioned that praying mantises were appearing indoors, around houses, and in places where they appeared to have become more common.
«"They've been around since 2017, but the heatwave has caused their population to explode," one commenter wrote.
A memorable encounter in a backyard or garden can be a valuable source of data for researchers trying to understand how wildlife habitats are changing.
What can I do?
The report of a sighting of a praying mantis to NABU could help researchers create a clearer map of the insect's distribution in Germany.
Commentators cautioned against re-submitting information about the same sighting. They noted that confirmed sightings from NABU, obsIdentify, and iNaturalist ultimately enter GBIF, so an observation already recorded through one of these services should not be re-submitted through another.
Citizen science alone won't solve the problem of large-scale environmental change, but it can give scientists a clearer picture of what's happening on the ground—and, in this case, in gardens, homes, and neighborhoods.
