Researchers report that a close-up smartphone photo submitted through NASA’s GLOBE Observer app showed a mosquito larva collected from a tyre in Antananarivo. The image was taken in 2020 and was found two years later when scientists reviewed historical data.
The team led by Ryan Carney trained AI image-recognition tools on thousands of verified photos. Using those tools, they developed a citizen science method that helped confirm the larva as Anopheles stephensi. The World Health Organization warns that this species is a growing threat to malaria control in Africa.
The researchers point to three free apps—iNaturalist, Mosquito Alert and GLOBE Observer—and say people with a smartphone and a 60x clip-on lens can send close-up photos. They also recommend using the Global Mosquito Observations Dashboard, but note that lack of phones, internet and awareness can limit participation.
