Troutnut Forum > Fly Hatch Talk > An odd observation of Hexagenia
This topic is about the Mayfly Genus Hexagenia
These are huge mayflies. Hexagenia limbata, by far the most important species, is the second largest mayfly in the United States. The largest is its close relative, Litobrancha recurvata, which until recently was also in the genus Hexagenia.
Two minor species, Hexagenia atrocaudata and Hexagenia rigida, may be noticed later in the season than limbata.
Read each species page for emergence and other details.
There are 23 more specimens...

| Fairbanks, AK Posts: 1115 | I'm reading up on mayfly rearing in preparation for this season, including Needham's 1935 classic "The Biology of Mayflies." (Very rare and somewhat outdated, but the most comprehensive book ever written about mayflies by far.) I found this quote strangely casual:The eggs of Hexagenia may be obdatined from a subimago by placing her on the surface of a beaker of water and snipping off her head. She will pour them all out immediately from both oviducts -- in the case of H. occulta some 5000 of them (Needham 1908, p. 260). I've got to wonder who first thought to try that. | |
