Staying Current

The documentation provided herein is subject to continuous change and modification as researchers continue to learn more about the species makeup of mayflies in North America, their relationships, and their distribution. The electronic medium, in addition to allowing ideal searching and indexing capabilities, allows the documentation to remain continually current.

Immediate updating is possible as new data are published. The contents will be updated on a continuous basis, at least annually, as of the Current Update, given above. With such a large and detailed documentation, it is possible that inadvertent errors and omissions have occurred, even though every effort has been made to eliminate them. The data presentation has been proofread by mayfly specialists at Mayfly Central and elsewhere.
