Hoverfly sightings w/c 5th October 2025

How many hoverflies are still around after storm Amy?

Date 5^th October: Time of recording 3-4pm, Location Barnsley Main. Gusty winds just after storm Amy.

Common Banded (Syrphus ribesii) 9♀+1♂, I do wonder whether there were some Hairy-eyed Banded (Sryphus torvus) as not all were captured. Common Dronefly (Eristalis tenax) 1♀ on Bristly Oxtongue (Picris echiodes).

Hoverfly - Greater Hornet Plumehorn (Volucella zonaria)

Greater Hornet Plumehorn (Volucella zonaria) Size: 15.5-19.5mm Flight: May-Nov

Species of the week – 6^th October

This our largest hoverfly (In the U.K) and if you have seen one you can probably understand why it’s often mistaken for the European hornet Vespa crabo, and with good reason. Its markings mimic the hornet in both colouration and design, a classic example of Batesian mimicry. However, this hornet mimic will not sting, bite or get aggressive defending a nest, as doesn’t have one and is often seen late summer and into autumn on a warm day.

 

Hoverfly - Yellow-barred Peat (Sericomyia silentis)

Yellow-barred Peat hoverfly (Sericomyia silentis) Size: 9.5-14mm Flight: May-Nov.

Species of the week – 29^th September

This hoverfly was the star species w/c 15th September and for good reason. It was not only a new species for the year but according to my records a new one ever. What was strange was that it was observed and identified in a Sheffield garden, not in the uplands where this would be typically found. As its name implies it is one of those hoverflies associated with uplands, as its long-tailed larvae are often found in peaty pools or wet rotting wood, feeding on the detritus soup.
 
So why was it discovered in a Sheffield garden when it favours acid wetlands and heathlands?

Hoverfly sightings w/c 22nd Sept 2025

When spotting hoverflies out in the field I try to find that hoverfly hot spot, this might be a glade, a woodland edge or just a flower bed. At this time of year finding that hotspot becomes a little more challenging as most of the flowers are past their best. But there is one plant that comes into its own at this time of year and that is the flowering of Ivy Hedera helix. I let it grow in my garden in the hope that come autumn it might become a hoverfly hotspot.

Hopefully I have grown a good crop and over the coming weeks it will provide me many hours of hoverfly watching just outside my backdoor.

Hoverfly - Footballer (Helophilus pendulus)

Footballer (Helophilus pendulus) Size: 11-15mm Flight: Apr- Oct.

Species of the week – 20th September

If you have a pond then this hoverfly is a likely visitor to your garden, especially around July when their numbers peak. Although its now coming to the end of its season there are still a few about, often seen basking on a leaf. See blog Garden Hoverflies

The thorax has pale yellow stripes and because of this is commonly called the footballer, as it resembles a football shirt, in particular Hull City with their amber and black striping. Other names for this wonderful species are the Tiger, which is the nickname for said football club. It is also the thorax design of this blogger's logo, chosen because of its distinctiveness. The rest of the logo design is not of Helophilus, however more information about this in a future post.

Hoverfly sightings week commencing 15th Sept 2025

Tale of Two Gardens

Stairfoot Garden 15th Sept – around 4pm

It's been a bit of a mixed weather week, a little wet & windy although still quite warm. The flora in my garden is now a little sparse, but it was nice to have the Great Pied Volucella pellucens drop in to visit the still flowering buddelia, this was the first sighting for the year in the garden.

Hoverflies Logged: 

Great Pied (Volucella pellucens), Common Banded (Syrphus ribesii)

Hoverfly sightings September 13th 2025

Stairfoot walk along the Dearne 13^th Sept 2.30-4pm

16 degrees, sunny intervals slight breeze

We went looking for migrating butterflies and hoverflies after watching a video by Trevor Pendleton on the Youtube channel 'Ramblings of an Entomologist'. See link below if you would like to watch.

We certainly didn’t get a Clouded Yellow (Colias croceus) but we did see a Large White (Pieris brassicae) in a hurry heading in the Sheffield direction, was it migrating?? There were however a few Small Copper (Lycaena phlaeas), a Small White (Pieris rapae), a couple of Speckled Woods (Parage aegeria) and a Red Admiral (Vanessa atalanta) in amongst the bramble, not sure they were going anywhere.

On the Hoverfly front:

Hoverfly - Striped-backed Glimmer (Riponnesia splendens)

Striped-backed Glimmer (Riponnesia splendens) Size: 5.5-7mm Flight: May-Sep

Species of the week – 13^th Sept

This is not a common species and would seem to be localised, with only 1479 records listed on NBN as of September 2025

https://species.nbnatlas.org/species/NBNSYS0100005170#overview

This species is in a genus all by itself within the U.K, having previously been listed under the genus Orthonevra due to its morphological likeness. Prior to this it was classified in 1822 under the genus Chrysogaster, again a not too dissimilar morphological grouping.

Yellow-girdled Fleckwing (Dasysyrphus tricinctus) 7.25-10.25mm Flight: Apr-Sep

Species of the Week - 6th Sept

Yellow-girdled fleckwing (Dasysyrphus tricinctus) is a widespread but not an abundant hoverfly, with August/September being a good time to spot them as adults are known to visit yellow composites and white umbellifers, particularly on edges of lowland woodlands, parklands and coniferous forests. 

Hoverfly sightings August 2025

This page will list hoverflies and notable species seen at various locations within the UK throughout the year.

♂= male   ♀=female

Littleworth Park: Lundwood 31st August Nature Walk 4.5miles 

5+ ♀ Common Dronefly (Eristalis tenax), Batman (Myathropa florea),♀ Interrupted Globetail (Sphaerophoria interrupta), Common Compost Hoverfly (Syritta pipiens), Candlestick Dronefly (Eristalis arbustorum), Cheilosia sp.. 6 species

Other Notable Species seen: Migrant Hawker (Aeshna mixta), Small Heath (Coenonympha pamphilus), Goldenrod (Solidago virgaurea)

Hoverfly - Batman (Myathropa florea)

Batman (Myathropa florea) 7.5-12.8mm Flight: May-Oct.

Species of the week - 30th Aug

Batman (Myathropa florea) so named because of the markings on the thorax which resembles the batman motif, which makes this very distinctive and easy to identify in the garden. But if you are struggling with seeing that image, due to variation, then try to visualise a human face as its other common name is the dead head fly due to the pattern resembling a 'death mask'. Often seen around landing platforms of an umbellifer or ivy flowers, with the male hovering in a shaft of sunlight just above a flower as it waits for a lady to land.
