Hi * locality - Silgueiros - Viseu - PORTUGAL * date - 2007.04.16 * size - 4 mm (small-medium fly) * habitat - openland * substrate - grass I think this could be Lonchaeidae. If so, it would be great to get species level because diptera gallery has just 3 photos for this family! Let me know if I'm right or no... EDIT ---> Changed the title "Lonchaeidae???" to "Lonchaeidae fly - Dasiops cf latifrons " jorgemotalmeida attached the following image:  [194.76Kb] Edited by jorgemotalmeida on 20-04-2007 08:39 |

Yes, that's a lonchaeid. But in this family identification of the species from an image is either heroic or crazy. Sorry. Regards, Dieter |

Jorge / Deiter I will go for the heroic rather than the crazy !! This species has a rather small antennal flagellomere a very wide frons and wide genae so my guess on a genus would be Dasiops . Given the relatively large size, yellow basal tarsomeres and yellowish wings along with its occurence in a grassland habitat I would go for D. latifrons, a relatively common southern and central European species whose larvae form galls on grass stems. - Lonchaeids are sometimes not too difficult really ...........

thank you a lot! good news: I collected Lonchaeidae fly.  Please provide me the address. PM me.  Indeed, I saw this in a specific site where we can find some Lonchaeidae flies. (I would provide more later the photo of typical site where I found these Lonchaeidae flies.) Now we can be sure about your possible ID. But I would like to know which characters that give us UNDOUBTEDLY clues about genus/species level. Let me know.

Is it common to see these flies hovering in the air about 30 s or more? I think I saw them hovering below a tree of Eriobotrya japonica (joquat) and near I could see Phoridae flies flying up-down ) with hind legs stretched.

I hope someone can answer to my question. Or the ethology of Lonchaeidae is unknown ? Thank you. |
