14 September 2007, New Brunswick, Canada. Both flies collected on trail in dense woods. There was some discussion recently about the usefulness of wing venation for diagnostic puposes. 2 'types' of Tachinid wings. Top: Phasia sp.; bottom Tachina sp.

that second venation in Tachina.. is something! I never saw such unusual deviation in M vein. |

I compared a couple of Phasia photos of mine, P. obesa and P. pusilla. They differ in some ways. The petiole is longer in P. pusilla. |

Wing of a North American Microphthalma sp. (Tribe: Dexiini) showing long appendix of vein M (A) at its bend; similar to that of the European species. -------------------------------------------------------------------------------- Tony T attached the following image: Tony T attached the following image:  [28.09Kb] Edited by Tony T on 21-09-2007 00:49 |

Another configuration. Note the right angle bend in vein M followed by a long smooth concavity before straightening to join wing margin just behid apex of R4+5. Also note the sinuous curve of cross vein dm-cu (discal medial-cubital) Tony T attached the following image:  [43.55Kb] |
