This little fly, about 5 mm. long was observed 23.september 2007 on a building site in the middle of a little town in Denmark on Tanacetum vulgare. Could it be Ensina sonchi or a related species? Best Ruth Ahlburg Ruth Ahlburg attached the following image:  [93.62Kb] |

It was mostly the black markings, that made me ask. Thanks for your comment and links. Ruth |

I wouldn't want to call the wingpattern 'black', but rather faint brown  But you're right, this species is rather variable in its wingpattern, normally it should have a very faint pattern at the top, with a well pronounced pterostigma. But the pattern at the top may be absent. Nevertheless it's quite easy to recognise by its general body colour, being yellowish grey. John |
