<DIV>Dear all,</DIV>
<DIV> </DIV>
<DIV>considering overwintering Syrphidae, I’m getting more and more convinced
that no European species has this overwintering as adult as only strategy. In my
opinion it always are species that have many generations a year and more
generations in warmer climates than in colder climates. All these species you
might find on the wing in winter in the Mediterranean. In more temperate areas
they will get less and less active with dropping temperatures. Both males and
females will start sheltering somewhere in colder periods. As long as
temperatures (or other circumstances?) are not to bad, most will survive.
Eventually most will die, males much faster than females. At the end of winter
only few will still survive, all of them females. Whether they have offspring or
not I don’t know.</DIV>
<DIV>I remember that someone has written on this subject regarding Eupeodes
corollae somewhere in Germany. It fits well with all species people listed:
Scaeva selenitica, S. pyrastri, Eristalis tenax, Episyrphus balteatus. You will
find males and females in late autumn, often much more females than males. And
in spring you only find females, at least in the Netherlands. And these species
are also the most abundant migrating species. Eristalinus aeneus also hibernates
as adult in the Netherlands. It has several generations a year, but I am not
sure whether E. aeneus migrates regularly.</DIV>
<DIV> </DIV>
<DIV>Best wishes </DIV>
