Tonight while sitting here watching my tank, I noticed a few of the Fuscum nymphs standing on a rocks. Something was a bit different with the way they were standing though. The bodies had a reverse like arch on them. I turned my head for a second and the next thing you know, I have a Grey Fox flying around my tank. Watching the other one, I quickly raced for my video camera to tape the emergence. Well, wouldn't you know it, I couldn't get the damn thing to focus but did get the emergence on tape. It was pretty cool to say the least however, I can't say the video came out that great. (A bit blurry).
First, the head of the nymph shell splits open and moves forward. Then the wing case splits in half and the mayfly breaks free. He swims extremely fast to the surface and starts flapping its wings and finally flies away. The wings on this mayfly appear to dry instantly as it only takes but a few seconds for this dun to leave the water. I can't see trout going too far out of their way to catch this very fast emerger. It took all but a few seconds to reach the water surface and fly away.
So how do you fish a Grey Fox hatch? I can't even see the emerger raking in that many fish being that it's so fast and doesn't sit on the water surface at all.
Anyone care to see the really lousy video of the actual emergence? |
