i didnt notice that before on the link oops!, i listened to the recording and it certainly was peculiar.
it wasnt constant, but varied.
allmost like the stuggling sounds you get from trapped flies in sarracenia tubes...

Excellent Hagen. Everyone should go and listen. Left of the 3rd row of flies click on Hörprobe gefällig? The high pitched 'scooter' is the Narcissus fly.
Mark, "scooter"? I'm unfamiliar with that in terms of sound? Are you meaning the higher squeal, a bit like air escaping from a balloon? There are so many different buzzes in that sound byte that I don't know what I'm supposed to focus on, or are they all Narcissus fly? |

I think Paul, when they have been squashed by Hagen they sound much higher.

So it's more of an echo-ey sound then, not that high pitched one that buzzes by in the sound byte?

Ah scooters. Now there's an annoying sound! Not for nothing are they called Vespas  |

Several flies there doing different things. The lower pitched sounds are flies in flight. The higher pitched ones are the trapped flies just vibrating their wings. |

Please have a look to the vains/wires of the wings. This is most important to differ the narcissus fly from others |

With some word from Forumists that early Narcissus flies have been seen, I remind you bulb growers to be vigilant. Seems VERY early, but you never know! And a reminder of the page from the Old Forum on this subject... http://www.srgc.org.uk/discus/messages/8/22416.html |
