Abstract Shorter, warmer winters linked to climate change are inviting the northwards expansion of mosquito species (Diptera: Culicidae) and the pathogens they vector. Monitoring can play an important role in helping to mitigate the health impacts of mosquito-borne disease due to changes in regional mosquito species composition. To update the inventory of mosquito species currently residing in Nova Scotia, we sampled adult mosquitoes from 60 locations using Centers for Disease Control and Prevention light traps and collected mosquito larvae from 232 water sources across nine ecozones from May to October in 2021 and 2022. Of the 12 652 mosquitoes collected, we identified 35 species, including eight species not previously recorded in the province: Aedes aurifer (Coquillett) , Aedes decticus Howard et al ., Aedes pionips Dyar , Aedes hendersoni Cockerell, Aedes sticticus (Meigen) , Culiseta minnesotae Barr, Culiseta melanura (Coquillett), and Culex salinarius Coquillett. We have also observed the province-wide expansion of Aedes japonicus (Theobald) since the species’ first detection in Nova Scotia in 2007. Overall, vector species are being detected more frequently in Nova Scotia, highlighting potential changes in disease dynamics as climate change progresses and furthering the need for continued monitoring.
