Hi, ID possible? Photo on Finland Kokkola 19 July 2021. Could this be the mine of Chromatomyia? Thank you in advance for any help in identification, Pentti Pentti Ketola attached the following image:  [247.73Kb] Edited by Pentti Ketola on 23-01-2022 15:39 |

Hi Pentti, I think you are right with Chromatomyia and probably it's the polyphagous C. horticola (we can see the frass in isolated grains, but other C. do it the same way). https://bladminee...+horticola https://agromyzid...y/term/216 Greetings, Eric Kloeckner |

Chromatomyia syngenesiae is also known on this host (https://agromyzidae.myspecies.info/node/1382) and forms identical mines to horticola, adults must be reared. |
