Maybe it had a tickle that it just couldn't scratch without a thorn ... and then it all went horribly wrong?

There is a bird in Australia, the Pied Butcherbird, that does this with birds it catches. Young from nests I think. But flies ...... ? |

European shrikes use to impale their preys (insects) on thorn like this.

I think a shrike is unlikely to impale a Pollenia without causing other damage. This is just an unlucky fly - perhaps caught in a gust of wind?

Last summer I saw a fly with its head caught in burdock. |

I've seen flies impaled on the tips of marram (Ammophila) and have presumed that they have been caught out by an untimely gust of wind. Steve Steve Crellin steve_crellin1@hotmail.co.uk Isle of Man |

I haven't seen a fly impaled, but I saw a small fly which could have been Anthomyiidae or a Muscid floating on top of my water barrel in late 2009. It had a broken wing but I rescued it, placed it on the rim below the top which had water sitting in it. The fly climbed back onto the water so I left it! I had a feeling it knew it wouldn't survive so was committing suicide as it wouldn't be natural to be on water and it was cold. I had some pics but I deleted them recently.
