First season I've really devoted to hoverflies so I don't know if it is common to have eristalis in such high numbers (mainly pertinax but also lots of tenax)
Hogweed seems to be the plant of choice for most of the hovers in my local patches.
Must have been well over 200 mixed eristalis in one small patch at Thrislington NNR.



Now I'm not sure of this hovers ID (so help there would be nice) but I do know it has been infected with Entomophthora muscae fungus as were others (including a honey bee which was frantically moving around a knapweed in a random manner and sticking it's abdomen straight up into the air). There were also a lot of dead hovers on plantain - possibly after infection.

Hi John

I think this is quite an unusual event in modern terms, although historically one would see very good numbers of hovers at hogweed, often dominated by Eristalines. The Melanostoma scalare are interesting - affected by a fungus - a nasty end!

Hello John

Here in Norfolk I have a stretch of rank, old Privet which flowers copiously and it is inundated with tenax/pertinax - this is an annual occurrence, at least here.

I am in an agricultural area and, unfortunatly, flowering plants are at a premium. The Privet is quite a magnet for bees, flies and butterflies. If anything unusual turns up then I usually find it around the Privet or on the remaining Hogweed.

Regards
Neil

Also seems to be very large numbers of V. bombylans and V. pellucens.
