The current study presents a success story where through a small network of citizen scientists original information regarding the occurrence of Aedes cretinus was received, suggesting the absence of invasive Aedes species on the island of Cyprus. Citizen science records show that Ae. cretinus most likely has an island wide spatial distribution while its seasonal activity is limited to the spring and summer months. Data collected by citizen scientists under ‘The Three Mosquiteers’ citizen science initiative, provided more records than any efforts from the authorities in the last 73 years. The future success and the longevity of this initiative will be strongly dependent on the in-depth engagement and collaboration between local experts in entomology and citizen scientists.
