|The distribution of Volucella Hoverflies in Nottinghamshire|
|The Genus Volucella, is
represented by some of largest and most spectacular
Hoverflies. Unusually for Hoverflies and Diptera in
general, they are all fairly easy to identify to species
Two are excellent Hornet mimics and there is one Bumblebee mimic. All are associated with Bee and Wasp nests, either scavenging from the bottom of the nest or (in the case of Volucella inanis) as ectoparasites of Wasp larvae.
Nectar sources for Volucella Hoverflies
All our Volucellas occur as adults from mid-Summer to early Autumn, visiting flowers such as Bramble, Devil's-bit Scabious (Succisa pratensis) and a range of Umbellifers. Fennel (Foeniculum vulgare) is particularly attractive.
they are strongly attracted to the flowers of Buddleia,
but the hardy perennial Astrantia (shown in the
accompanying photographs of Volucella zonaria
and inanis) will certainly also attract V.
Nottinghamshire distribution of Volucella zonaria, inanis, pellucens and bombylans
Volucella zonaria has the most restricted range in Nottinghamshire of the four species. Based solely on the records we have, or which have been sent in to us, V. zonaria is uncommon within suburban Nottingham, but considerably rarer in rural areas. V. inanis has moved north through the UK in recent decades and the number of Nottinghamshire records has also increased. Up to four V. inanis were recorded by Pauline Bradford, from the Nottinghamshire Wildlife Trust's Dyscarr Wood in the north-west of the county during 2014.
recorded many Hoverflies at Dyscarr Wood during the
course of 2014 and kindly provided us with her records
for inclusion into the Nottinghamshire distribution maps.
Her meticulous recording, also provided us with the
chance to use her data to show the numbers of Volucella
pellucens at Dyscarr, over the Summer months. V.
pellucens is the commonest of the Volucellas
across Nottinghamshire, and the above graph shows a peak
count of 88 on June 20th.
Volucella bombylans is another common Hoverfly, found more widely than the number of records on the distribution map might suggest.
|Volucella zonaria (Poda, 1761)||Volucella inanis (Linnaeus, 1758)|
A very large Hoverfly, Volucella zonaria
is one of two Hornet mimics, but much larger than the
equally impressive V. inanis. The chestnut
colouration is distinctive enough to seperate it from V.
inanis, although both share the strong yellow
suffusion to the wings.
Nottinghamshire distribution: Apart from a single record at Dyscarr Wood in the north-west of Nottinghamshire, most records are from the suburban areas of Nottingham, where it is attracted to garden flowers. We have seen V. zonaria in company with V. inanis.
Another large and spectacular Hornet mimic. It
is still described as being local, and has appeared in
several counties (including Nottinghamshire) since the
Nottinghamshire distribution: From the records we have, V. inanis has a similar Nottinghamshire distribution to V. zonaria and the two can occasionally be found in suburban gardens together. All records are from sites west of the River Trent, but this may well be due to observer coverage than a westerly distribution.

|Volucella pellucens (Linnaeus, 1758)||Volucella bombylans (Linnaeus, 1758)|
V. pellucens is one of our most
distinctive Hoverflies, being a large species (like all Volucellas)
with a distinctive white band across the abdomen.
Nottinghamshire distribution: More widely distributed and found in a wide range of habitats, across the whole of Nottinghamshire than the other three species, V. pellucens can be expected wherever there are flowers. Creeping Thistle seems to be particularly attractive to them as a nectar source. Does turn up regularly in suburban gardens .
This is the only Bumblebee mimic of the UK's Volucella
Hoverflies. There are two colour forms, with the
commonest shown below, plus an all black form with with
orange/red at the end of the abdomen. The antennae are
distinctly plumose (feathered).
Nottinghamshire distribution: Found along woodland rides, the edges of woodland and grassy habitats etc, occurring fairly commonly across most of Nottinghamshire.
