Comment: 1,436 mosquitoes (5.9% of all specimens collected) were identified as Ae. cinereus. This species is abundant in Estonia and can be found almost everywhere from June to September. Also, Ae. cinereus can be numerous at times, especially towards the end of the summer, based on the data of the present study. It should be noted that adult females are difficult to differentiate from the closely related Ae. geminus based on morphology alone; thus, specimens of Ae. geminus could also be among the specimens of Ae. cinereus collected during the study.
