Dodds first described A. velox in this paper. Quote from page 106: " Common in South Boulder Creek and its tributaries where the water is not very swift, between 5,500 and 11,000 feet. It also lives in lakes and ponds with clean bottoms. It is a very strong swimmer, being found in swifter waters than any other swimming form of this region."

Remarks about A. velox from page 28: " One of several species of mayflies described by Dodds (1923) in his study of upper South Boulder Creek in Boulder and Gilpin Counties. All SPRB records of this species are from the Boulder Creek basin in Colorado. Specimens were collected from 1631 m to 2809 m in elevation. Adults were present from June to July. "
