if anyone believes in reincarnation (in another animals) this fly can be the decapitated Louis XVI.  |

Once I tried to catch a very fast flying dragonfly (Odonata) with my dipteranet. After several futile attempts, suddenly I got it after a good and firm swing. Looking inside my net I found the poor creature, decapitated! It seemed dead.  I took it in my hand and after a few seconds... it suddenly tried to fly away... It scared the hell out of me! I never found the head to mend this broken heart. |

I have a reponse from a french entomologist professor. the head is hiding in the thorax. he can see the flat eyes and the palp. conclusion : malformation. jean-claude Edited by jean-claude bernard on 25-02-2008 18:19 |

All the "higher" flies make use of the ptilinum which they inflate to push off the end of the puparium. Without it, the fly would be trapped and unable to escape. I don't believe this fly can have had an effective ptilinum without a fully formed head. I suggest that all Pollenia look like this when their head is removed. (Have just decapitated a dead Calliphora - looks very similar.) Tony ---------- Tony Irwin |
