Sepsidae flies mimic winged ants quite well, like this one (a Australosepsis sp.?) Joaquim Gaspar Alvesgaspar attached the following image: ![]() [194.96Kb] |

While I was scanning recent posts, I saw the thumbnail image of this picture out of the corner of my eye, and wondered why someone had posted an image of a scorpion (rather than a crayfish)- perhaps a potential predator might make the same mistake, and leave it alone? ![]() Edited by Tony Irwin on 02-10-2007 21:28 Tony ---------- Tony Irwin |

Need a photo of a Rhagoletis from behind ![]() According to Marshall "the wing-banding pattern....seen from behind.. makes the fly look remarkedly like a jumping spider (the bands look like spider legs)" Who wants to tangle with a jumping spider? Edit: Further reading indicates that the mimicry is to fool jumping spiders as these spiders are the major predators. "Greene et al. (1987) and Whitman et al. (1988) showed that Z. vittigera mimics jumping spiders and is significantly protected from these common predators on its host plant. During the fly's wing flicking displays, its wing pattern resembles the legs and the abdominal spots the eyes of a spider in its own territorial display." See: Reference here Tony, really this is quite distinctive. Even in dorsal view (see the back of the fly) it seems a salticid spider!! (very convincing) . See here >> http://www.dipter...to_id=2344 |

When i saw the picture of Rhagoletis from afar, (or without glasses ![]() What about Celyphidae? Does looking like a beetle confer any protection? And I believe their flight isnt that great either?as mentioned in the Threads. |

The nice pair of lateral + dorsal photos that Tony T posted earlier in this thread (see below) show a very dark specimen of Physocephala furcillata...which is pretty much the only conopine that seems to make it as far northeast as New Brunswick in North America. Tony T wrote: This is a North American Physocephala sp. (Conopidae) that closely resembles a Potter Wasp (Hymenoptera: Vespidae: Eumeninae). ![]() In fact, when I first saw this fly on a flower I thought it was a Potter wasp. Length: 10.5mm excluding antennae. 19 September 2007, New Brunswick, Canada. |
