Hi, At beginning of july i have been up in Retezat National Park. In a lot of places i have found galls (rolled leaf) on Dryopteris filix-mas. From what i have read he causer is an anthomiid Chirosia betuleti. Are also other species associated with this fern? I ask this because from what i seen on Fauna Europaea is not present in Romania (the closest country in which is signaled is Slovakia) ( http://www.faunae...on1=129180 ). If is this species and not yet signaled will be good o have some adults i think, how to proceed for this? First photo: the gall Thanks for the help, cosmln [EDIT]: title updated cosmln attached the following image:  [118.85Kb] Edited by cosmln on 25-07-2008 21:17 |

This is particularly interesting to me. If you pick the galls when the larvae are fully grown, place the galls on some damp sand in a container. You might be lucky and the adults will emerge (?when). I will name any adult males if you send them to me. There are no recorded Chirosia species bred from Dryopteris, but perhaps this name is a synonym of another genus? C. betuleti has been bred from Athyrium If you send me your email address by private message I will send you a PDF on a paper I wrote on Chirosia griseifrons and Athyrium |

I'm not sure if the thing with Dryopteris is not from the book with British Galls (the book is it at office and i will not be there until next week to check). Hope that this next week i will go up in the mountain and if still find larva i will collect some and hopping to have some adults. I will send you a PM with my email address. Also i don't know if you have seen this post: http://www.dipter...d_id=14630 , maybe you are interested in anthomyiid? Maybe i will not be able to put all in one place, maybe some will go at Nikita. thanks a lot for your help, cosmln |
