Hi, we found mines in leaves of Ranunculus auricomus. Unfortunately we did not succeed to identify with the key of http://www.bladmineerders.nl/plantenf/pfranunculaceae/ranunculus.htm It is a upper surface gallery, corridor mine. hardly any frass visible. If present, small granules in a row. Pupation probably within the mine (or outside?), exits were found in the upper or lower surface of the leave. Most of the mines were empty. We found one insect (pupa?), probably a Hymentoptera. Found in Germany, Lower Saxony, Göttingen, ourdoor exprimental area of the University. Any idea? Thanks a lot Thomas Edited by Thomas Brand on 17-06-2014 12:46 |

Hi Thomas, the lower pupa could be from a chalcid wasp (superfam. Chalcidoidea, maybe Pteromalidae) - probably a parasitoid antagonist of the miner itself. Maybe it'll hatch soon!? Best regards from Kassel, Marc |

Thank you Marc, this would explain why we could not identify the miner. The situation was found as in pic 3 - within the mine the wasp close by a casing, maybe the rest of the mining larva. Well, this could be one of the Phytomyza species described on Ranunculus. Thanks a lot Thomas |
