Fico,
what is your area ?
-As you say, millions of wasps exiting mamme figs on the first of May, lead me to believe that at that time there were thousands of receptive Profichis ready to give shelter to those wasps..and to fill their galls with eggs for the spring generation of wasps (Profichis)
-if this was true, and if Nature did not bring about any climatic extremes, you should have by now plenty of Profichis about becoming ripe and ready to send out millions of wasps (with good pollen) .. -wasps born from those 1stMay eggs.
you may verify this opening a fig and checking what the galls look like
Caprifigs around the S.Francisco Bay fields may well be now ripening the very first Profichi figs
In my area the process is over.. pollination is practically finished.. no more Profichis available but enough Mammonis already receptive, on the green wood of the year taking wasps inn and to start another cycle.
