In the East and Midwest this is one of the most important hatches of the Spring. They are large flies which emerge sporadically, making for long days of good fishing.
This species contains the two classic Eastern hatches formerly known as Stenonema vicarium and Stenonema fuscum, the "March Brown" and "Gray Fox." Entomologists have discovered that these mayflies belong to the same species, but they still display differences in appearance which the trout notice easily. Anglers should be prepared to imitate both types. Read more...
There are 16 more specimens...

Administrator Bellevue, WAPosts: 2737 | They're not just in the same family -- they're both the same species, Maccaffertium vicarium. But they are still distinct color variations within that species. In the specimens I've collected, it seems the "Grey Fox" ones are a little smaller and stockier, and with more gray or amber shades than brown. The hatching periods and behavior are generally supposed to be the same. Just carry patterns for each variation and try to scoop up a live one on the stream to decide which to use. | |

Administrator Bellevue, WAPosts: 2737 | I thought "gray fox" were fuscum?.......did they eliminate that species when they went from stenonoma to maccaffertium? Yeah, they eliminated fuscom. I don't think it was in the same paper that bumped all but one of the Stenonema species over to Maccaffertium, but it was probably around the same time. | |

Administrator Bellevue, WAPosts: 2737 | I stand corrected, then. I didn't realize fuscom was ditched before I was born! | |
