Montana Counties

This distribution chart is a compilation of information from Paul Opler's Moths of North America Website, the Lepidopterists' Society Season Summary, Lemaire's Hemileucinae 2003 and personal communication with many residents of Montana. See comments below the map.

Actual ranges may, in many cases, be more expansive than noted.

Although no markings appear for Antheraea polyphemus (except Missoula and Lincoln counties), I suspect it is widespread throughout Montana.

Hyalophora kasloensis is probably limited to the Bitterroot Montains (Missoula, Ravalli) in the western portion of the state, while Hyalophora cecropia is probably limited to the eastern half of the state.

Clicking on a scientific name will take you to a file with pictures and/or information.
