Hi !
There are several large plants of Bryonia dioica in my garden (Heron, Belgium) . There has been this year a good sized population of the tephritid Goniglossum wiedemannii. They are now on the decline, but there is a pullulation of a small braconid (Opiinae, I think) constantly patrolling the plants.
Is there anywhere I could learn about this association, how specific it is, etc... ?
Thanks in advance for your comments
Philippe
