[2] This species is commonly found in forested areas, particularly in moderately deep snowpools lined with heavy leaf litter.
The species follows a univoltine life cycle, meaning it produces a single generation per year.
[1][3] The larvae of Aedes excrucians are relatively large, with distinctive features such as a long, slender siphon tube.
The pecten teeth on the siphon are detached, distinguishing it from similar species like Aedes fitchii.
However, its role as a vector for human diseases appears limited compared to other Aedes species.
