Hi, in the forest yesterday I was sure I have Eurithia anthophila in my net, but now I can see I was wrong. Any idea Chris ? June 17. 2010 Loviisa, Finland Jari JariF attached the following image:  [158.53Kb] Edited by JariF on 21-06-2010 14:41 |

Ernestia sp. - possibly E. rudis?

Thank's again. I have Ernestia rudis but it has no yellow on sides of abdomen. Maybe this one is one of the two others we have. Jari |

Yeah, it should be fairly easy to key once you know it is Ernestia ... but the first couplet asks about black hairs behind the ocular row and whether it has hairs on the parafacial so I wasn't 100% sure on either of those It seemed to run to rudis fairly easily though is you try it with a bare parafacial, eye hairs yellow and crossed apical scutellars. I think the yellow side patches on most tachinids are a bit variable even on the same species.

It is rudis alright, sexual dimorph and moreover variable I have never seen vagans with reddish side marks and it clearly is not laevigata Theo |
