This topic is about the Mayfly Species Heptagenia culacantha
This species is not known to be important to anglers anywhere. It is noteworthy for its relatively recent discovery, its large size, and the striking coloration of its nymphs duns.
This is the largest species of Heptagenia on the continent, and it's also one of the largest in the entire Heptageniidae family, being almost the size of the March Brown, Maccaffertium vicarium. Nymphs and adult females have been collected with bodies up to a size of 19.5mm, a little over 3/4" long. Read more...

| Fairbanks, AK Posts: 1115 | I went to the entomology library today and photocopied the 1985 paper that first described this curious species. I've updated the culacantha page with this information. | |

| Mercer Island, WA Posts: 484 | Mark- There are two Heptagenia species, which could be present in YNP, H. elegantula and H. solitaria. They are often referred to by the common name, Pale Evening Dun. The emergence is generally in early to late afternoon, and the spinner fall is in the evening. For imitation of the emerging duns, I would suggest a Sparkle Dun, Compra-Dun, or Light Cahill with a creamish body in hook size #14. For imitation of the spent spinners, I would suggest a spent-winged spinner imitation with a creamish body in hook size #14. | |
