zug buggin 0 Report post Posted November 1, 2014 I using a very fuzzy memory but I think the Hendrickson sheads it shuck on the bottom then swims to the surface unlike most mayflies which swim to the surface then shead the nymph shuck http://www.troutnut.com/hatch/5/Mayfly-Ephemerellidae-Hendricksons-Sulphurs-PMDs-BWOs Quote Share this post Link to post Share on other sites

Randyflycaster 0 Report post Posted November 2, 2014 What's interesting and frustrating about this subject is that there is different opinions on whether some flies hatch on the bottom. For example, some hatch charts list Hendrickson's has being bottom hatchers. Two books I have say that they hatch near the surface. Randy Quote Share this post Link to post Share on other sites
wschmitt3 0 Report post Posted November 2, 2014 That video is absolutely BONKERS!!!!! Did they emerge into winged adults or just hatch from the egg into nymphs? Quote Share this post Link to post Share on other sites
SilverCreek 0 Report post Posted November 6, 2014 Normally, the females lay their eggs after fertilization, and then they die. These female mayflies keep the fertilized internally and the fertilized eggs mature and hatch into nymphs just after being laid 10-14 days later. The nymphs still have to grow and mature before hatching into duns a year later. http://en.wikipedia.org/wiki/Cloeon_dipterum Quote Share this post Link to post Share on other sites
Taxon 0 Report post Posted March 20, 2016 That video is absolutely BONKERS!!!!! Did they emerge into winged adults or just hatch from the egg into nymphs? Hi wschmitte- Most female mayfly imagoes lay their eggs within 24 hours of having them fertilized by the male imago. After those mayflies lay their eggs, it takes a several weeks for the eggs to mature, and for each nymph to break out of its respective egg. However, several genera of mayflies retain the eggs within their abdomen for a week or more following fertilization, which allows their eggs to mature, so that the nymph is able to escape its egg immediately.following the egg being laid, which is what we see happening in the video.
