The first photo shows very clearly the setulae, seta (e),[= bristle(s)] and maybe some spur(s) = spine(s)?

Certainly a female Linnaemyia but, after Theo's warning on this genus, I wouldn't like to say which species it was. |

maybe L. tesselans? Whatever it Linnaemyia is, this is a magnificent fly! |

what is the function of those many bristles and spurs in legs? It looks a little like an ancient roman chariot with metallic spurs on wheels... to cut something.  |

I'd guess it is sensory ... most bristles articulate in cups, which in turn contain a lot of nerves. But it's hard to understand exactly how the fly uses the data it gets from the bristles. Could be for sensing host movement or helping judge air-speed and direction in flight. |

I'll stick to my own warning. Tessellans, though, seems highly unlikely to me Theo |
