Hi, Yesterday I saw lots of these small flies sitting all around on the leaves. They certainly belong to Chamaepsila, and I would ID them as C. rosae. Do you agree? Thanks, Sundew Sundew attached the following image:  [179.9Kb] |

Could be, but rosae can only be separated with certainty using the male genitalia...

Doesn't possibly the frequency point to a species? Given that all the little ones I saw belonged to the same species (which I assume) and that there were many wild carrot plants (and in the gardens surely cultivated ones as well), isn't Ch. rosae not quite likely? Or are there similar other species that are equally frequent? |

That's a valuable link indeed! What a pity that not all pages are available. I see that Ch. nigricornis cannot be ruled out. It feeds on Chrysanthemum that is available as are the carrots for Ch. rosae. Hmmm... Unfortunately nothing is said about the frequency of the first species. Only the latter is said to be a pest. Many thanks, Andrzej. |
