A 2018 study of mosquito populations on the islands of Sint Maarten, Saba and Sint Eustatius documented eleven species, including two new species for Sint Maarten, a number of which are known to spread mosquito-borne diseases. Understanding mosquito populations can help local governments to counteract the spread of mosquito-borne diseases and provide insight in the health of local ecosystems.
