Hi everybady ,respect,
I live in Bulgaria(EU).Now , if you look at the map ,there is region in southwest BG ,south of Kresna village .Figs in that region are mostly Smirna type and there is a lot of spontaneous vegetation of Caprifigs.
The fig wasp is present also in Black sea region ,south of Burgas.
Even when I am ,on the northern slops of Rodopi mountain (Plovdiv-Asenovgrad region) we find a lot of spontaneous caprifigs.
Mi point is….minus 15C , even minus 20 C are not so rare in thous places.
Maybe the wasp is not so tender….
O-o-r ,if some years the wasp is death , is coming back from Greece and Turkey.
P.S. No wasp north of Balkan mountain (Stara Planina)
P.S.2 Ops ,I forgot, we have snow ,more o less ,but every winter.
