I see calypters.. hence no Lonchaeidae, neither Lauxaniidae. |

Are you sure ?? I thougt it was a reflection from the flits of my camera.. I don't have any foto's from Lauxaniidae of my own, so I wil look at the diptera gallery, for any resembles of this fly. Greatings Joke Edited by javanerkelens on 02-03-2008 22:52 |

white squama ; and near squama we can see clearly calypters! Agromyzidae are acalyptrate. It is not agromyzid. |

that translucid membrane below the wing is the calypter. The dull and white round thing is the halter - vestigial wing. SO this is not Agromyzid, neither Lonchaeidae neither Lauxaniidae (in spite of the fact it resembles a little for those families)  I can see strong posterior bristles on scutum and maybe a bare scutellum. |

do you have a lateral view showing all the lenght of the fly..? it would help to see better the calypter. |

Agromyza (Agromyzidae, obviously) Don't let the 'acalyptrata' monicker throw you off course: these flies do in fact have calyptera, only not as well developed as in (most) 'calyptrata'. The colour of the marginal hairs of these lobes (the 'squamal fringe'  is a frequently used character in Agromyzidae.

If I undertood you correctly: many diptera families have one (or two) points on the costa where the wein is interrupted or at least much weaker than normal. Agromyzidae is one of these families.

So, this tell us that we must be care about agromyzids and... |
