Comment: 206 mosquitoes (0.9% of all specimens collected) were identified as Ae. caspius. Aedes caspius is a halophilic species mainly found in Estonia near the brackish water of the Baltic Sea. These mosquitoes are common and at times numerous near the coastline, but are rarely found further inland. Thus, their relatively low numbers collected in this study is due to collection bias. Aedes caspius appears to be active throughout summer.
