Hi igor - does that mean the fly in this thread is also opaca? |

Hi Chris, No, the fly in the other thread is not Empis opaca. Jan Willem van Zuijlen |

Hi Jan Willem - thanks for the confirmation - what are the distinguishing features that would split opaca and tessellata in these photos? They look very similar, except perhaps for the degree of leg coloration but I thought maybe this was due to the difference between flash & natural light. |

It's not very clear in the photo's concerned, but the abdomen is dorsally dusted in Empis tessellata and dorsally shining black in E. opaca. The adbomen of E. opaca is dusted at the sides though.

Empis tessellata can have extremely red legs in warmer parts of Europe, like I found in Portugal. The base of the wing in this pic looks yellowish. This could be tessellata, also taking in mind that the thorax is very dusted. |

I agree, the fly in this photo certainly looks to have a dusted thoracic dorsum - showing distinct vittae. |

Empis opaca: palpus reddish yellow; scutum with 4 vittae. Empis tessellata: palpus black; scutum with 3 vittae. |
