This fly was in dry scrubby habitat at the Colca Canyon, Peru on 25th Sept 2012. We think it's a beefly, but any further ID would be gratefully received. Thanks. (Edit: well I got that wrong!) KateL attached the following image:  [154.56Kb] Edited by KateL on 23-10-2012 09:38 |

Here's another photo giving a better impression of the relative length of the proboscis:

This is a horsefly, Tabanidae, subfamily Pangoniinae (which have a long proboscis, causing confusion with Bombyliidae) Steve |

Thanks, that's very helpful. We'd considered that it might be a horsefly, but a friend thought that the wavy parallel radial veins made it a beefly. I don't know what the etiquette is here about off-topic questions - am I allowed to ask what it does with that probsocis? Is it just a nectar feeder or does it bite like the horseflies I'm more familar with? Edited by KateL on 22-10-2012 22:13 |

A Pangoninae in Central America with that wing would be Scione but I have no information about Peruvian Tabanidae. At least some species in the genus bite. |

Yes, those that bite then hover to suck up the blood! Steve |

That's amazing! Do the blood feeders also feed on nectar? Is it likely that a species with such a long proboscis as this one is a blood feeder? Do the relatively long hind legs give any clues on the flies feeding behaviour? Thanks! Kate |
