Yes, in Czech also overwinters Lapposyrphus lapponicus as female. Pavel L.

Dear All,
Now we have 23 degrees of frost. At this time we able to observe only white flies. Real syrphids will appear at April, at once after disappearance of snow-cover. They are males and females of 5-6 species from the genus Melangyna and only females (!!!) of Lapposyrphus lapponicus. I think that the later hibernates like to Bombus or social wasps after autumn copulation. Other adult syrphids start later.
Adults of Eristalis tenax are find in winter time at our cold buildings, but I did not see never specimens of this species collected before the beginning of July in Primorie (Vladivostok), the middle of July in Amurland (Komsomolsk) or the beginning of August in Sakhalin and Southern Kuril. It is possible, Eristalis tenax arrive to Russian Far East from southern regions annually.
About the hibernation of Lapposyrphus lapponicus there is single phrase in my paper: Life-history and phenology of the Far-Eastern hoverflies (Diptera, Syrphidae) – Natural-Geographic Reseachs/ Science almanac. Issue 2. Komsomolsk-n/A. 2004. Press of Komsomolsk-n/A State Pedagogical University. P.101-107 (in Russian).
With best wishes from snowy Komsomolsk-na-Amure. Valery

Good evening,
This is an interesting observation, is that this finding has been observed in countries such as Sweden, Norway, Denmark and Finland ?
Best wishes

With very mobile species like this, I wonder if they have travelled some distance from breeding grounds and are not strictly overwintering (in the sense of a diapause), esp as they are males rather than females. Auricollis can certainly be one of the commonest early spring syrphids here, but I don’t observe such a strong apttern as tenax & balteatus. Just for info, somebody sent me a batch of flies found sunbathing in a field centre at the end of December. 28 species – mainly muscids, anthomyiids & heleomyzids – included Polietes lardarius & meridionalis – which I think you know about.
Cheers,
Steven

I had Meliscaeva auricollis in my garden ( Belgium ):
2 December 2011 (2 males, 1 female)
15 January 2012 (1 male)
Hibernating?
Also very strange that 3 of them are males.
Best wishes,
Chantal

The main ones in Britain are Eristalis tenax and Episyrphus balteatus, the only two species you might expect to appear on a mild winter’s day (other spring species such as E. pertinax, Meliscaeva auricollis, Melangyna 4-maculata need a longer period of warm weather to emerge so are presumably at the pupal stage). I believe that Eristalinus aeneus has also been found hibernating in the adult stage in winter, but as a coastal species, such overwintering would be less noticeable.

Steven

Hello every one,
Let me
ask you because I like to know if there is publication on the hoverflies that would be able to spend the winter as adults.
Is it a
rare or known ? Does research have been done about it ?
Best wishes

Hallo Jeroen,
je zonnet.nl adres bounced (mailbox vol) dus dan maar ook via de maillijst. Hopelijk krijg je dit wel toe?
Voor mij ook een exemplaar. Heel leuk overigens dat je het werk van Jan Lucas afmaakt.
groeten,
Frank
