British hoverflies, Cheilosia illustrata, Chrysotoxum bicinctum, Episyrphus balteatus, Eupeodes corollae, Helophilus pendulus, hoverfly, Sphaerophoria scripta, Volucella pellucens, Xanthogramma pedissequum, Xylota species

Hoverflies seem particularly numerous this year … or maybe it’s just that I’ve been keeping more of an eye out for them. Here are some of the species I’ve clocked in the past couple of weeks. Looking through my photos again now, I’m struck by how diverse these lovely creatures are.

OLYMPUS DIGITAL CAMERA

Volucella bombylans: One of the bumblebee-mimicking hoverflies. This one was snoozing on a cool day, which is how I managed to get a nice close shot.

200618 chrysotoxum bicinctum

Chrysotoxum bicinctum: Its distinctive yellow bars make this hoverfly reasonably easy to identify.

OLYMPUS DIGITAL CAMERA

Episyrphus balteatus: Also known as the Marmalade hoverfly. Despite its small size, this species is known some years to migrate en masse to Britain from continental Europe.

OLYMPUS DIGITAL CAMERA

Eupeodes corollae: These two were otherwise occupied, which allowed me to get quite close to them.

OLYMPUS DIGITAL CAMERA

Helophilus pendulus: The ‘footballer’, because of the striped ‘footballers’ kit’ markings on its abdomen.

OLYMPUS DIGITAL CAMERA

Sphaerophoria scripta: Apparently, the yellow colouration is influenced by the temperature at which the larvae develop, so Spring-born individuals can be darker than those hatching later in the year.

OLYMPUS DIGITAL CAMERA

Volucella pellucens: One of Britain’s larger hoverflies; also known as the Great Pied hoverfly and the Pellucid fly.

200618 xanthogramma pedissequum

Xanthogramma pedissequum: This used to be easy to identify from its distinctive markings but, in 2012, the very similar Xanthogramma stackelbergi was added to the British list so now the thoracic markings need to be carefully checked to ensure the correct identification.

OLYMPUS DIGITAL CAMERA

Xylota species: I didn’t get good enough photos of this one to be able to work out whether this was X. segnis or X. sylvarum – you need very clear views of its hind tibia to work out which is which.

155/366 A new hoverfly

British hoverflies, Casehill Woods, hoverfly, Volucella inflata

Yesterday’s walk saw me exploring new trails – always exciting as I never know what I might find. I’d walked through part of Casehill Woods a couple of times before but in the winter months, when the ground was sodden and heavy with slippery mud, so it was nice to return for a summer visit – the first of many, I think. I particularly wanted to check out the woodland rides, for butterflies and other beasties – and a beastie is what I found there, a new-to-me and new-to-my-local-10km-recording-square hoverfly, Volucella inflata.

200603 volucella inflata

This gorgeous golden creature favours woodlands, and feeds on the flowers of Bramble and shrubs like Wild privet and Dogwood, so the habitat at Casehill Woods is perfect for it. These hoverflies should be on the wing for a few more weeks yet so I’ll be keeping an eye out for more when next I walk these paths.

148/366 Tiny surprises

British insects, Cardinal beetle, Eristalis nemorum, hoverfly, Nettle weevil, Swollen-thighed beetle, weevil

When you’re bright red, it’s hard to hide in the grass but it was still a nice surprise to spot this lovely Cardinal beetle, and it didn’t seem to mind me picking it up for a closer look.

200527 cardinal beetle

I was looking for the pupa cases of moths on a Wych elm when I spotted this weevil. It looked to me like a Nettle weevil, so it was a bit of a surprise to find it up in a tree.

200527 weevil

Speaking of weevils … As my eyesight is not very good, I sometimes don’t notice very small creatures, and this is a case in point. I had spotted the hoverfly, Eristalis nemorum, so took a few photos of that and didn’t spot the teeny weeny weevil until I looked at the photos on my laptop when I got home.

200527 eristalis nemorum

And the same is also true of the smaller bug in this wild rose. I saw the Swollen-thighed beetle, on the right, but not the other creature, until later. I love these little surprises from Mother Nature.

141/366 A Buff-tailed bear

British hoverflies, Buff-tailed bear hoverfly, bumblebee mimic, Cogan Wood, Cosmeston Lakes Country Park, Criorhina floccose, hoverfly

Bear? There are bears in south Wales? No, don’t worry, this Buff-tailed bear is a hoverfly (Criorhina floccose), a new find for me, from my first visit to Cosmeston Lakes Country Park in weeks (due to the Corona virus, the park was closed from 23 March until last Saturday 16 May). I initially thought this hoverfly was a variation of one of the other bumblebee-mimicking hoverflies, Merodon equestris, as they can be found in a wide variety of colours. But my record has been corrected by Mr UK Hoverflies himself, Roger Morris, and I now know the tufts of pale hairs at the sides of its abdomen are one of the main diagnostic features.

200520 Criorhina floccose (1)

These hoverflies are fashioned to mimic Common carder bees – see comparison photos below, hoverfly on the left, Common carder bee on the right. I think the hoverfly deserves an A for effort!

200520 Criorhina floccose (2)
200520 Common carder

Criorhina floccose is usually found in woodland – I found this one in a sheltered clearing in Cosmeston’s Cogan Wood, and there’s only been one previous record in my local 10-kilometre square. Now I know what to look for, I’ll be keeping an eye out for more.

37/366 My first hoverfly larva

British hoverflies, dormant hoverfly larvae, hoverfly, hoverfly larva, Platycheirus larva, Platycheirus species

When I first saw this creature, I thought it might be a butterfly or moth larva but I was wrong – nothing new there!

OLYMPUS DIGITAL CAMERA

Thanks to a Twitter pal, I now know it’s a hoverfly larva and, with some excellent help from an entomologist who specialises in flies, I also now know it’s one of the Platycheirus family of hoverflies but not which of their 25 British species.

OLYMPUS DIGITAL CAMERA

Apparently, little is known about the larvae of some species of hoverflies: their larvae have not yet been fully examined or described, so you really need to rear a dormant larva through to adulthood to be sure. Not knowing that, I left this one in the woodland where I saw it, but next time …

269/365 Still hovering

British hoverflies, Cosmeston Lakes Country Park, Eristalis nemorum, Eristalis species, Helophilus pendulus, hoverfly, Syrphus species

Despite the wind and rain of recent days, which continued through part of today, when the sun came out at Cosmeston there were still a few hoverflies about. I’ve forgotten everything I ever knew about hoverflies, which wasn’t much, but I think these are Syrphus sp. (these usually need microscopic examination to identify to species), Eristalis sp. (my photo doesn’t show enough details to be sure which species this is – maybe E. tenax), Eristalis nemorum, and ‘The footballer’, Helophilus pendulus.

251/365 Sericomyia silentis

#365DaysWild, Bog hoverfly, British hoverflies, Devil's-bit scabious, hoverfly, Lavernock Nature Reserve, pink scabious, Sericomyia silentis

It looks a bit like a wasp but this black-and-yellow-striped minibeastie is a hoverfly with the rather tongue-twisting name Sericomyia silentis. Perhaps Bog hoverfly would be easier but, in my opinion, its common name doesn’t do this little beauty justice.

190908 sericomyia silentis (1)

I spent a couple of hours today at Lavernock Nature Reserve, where the Devil’s-bit scabious is looking simply stunning and is attracting myriads of insects. I took lots of butterfly photos but thought to post one of the other little critters today. The Devil’s-bit is usually a lilac colour but some at Lavernock are this subtle shade of pink instead. Its nectar obviously tastes just as good!

#365DaysWild, British hoverflies, Chrysotoxum bicinctum, Episyrphus balteatus, Helophilus pendulus, hoverfly, Volucella bombylans, Volucella bombylans subsp. plumata, Xanthogramma pedissequum

I found a new path today, which led me through swathes of long grass bordered by brambles and low shrubby bushes. I emerged with wet shoes and trousers from the dew still coating the grass but with lots of photos of hoverflies, so I will definitely be going back to explore further. Here are the hovers …

190601 1 volucella bombylans
190601 2 volucella bombylans subsp plumata

Volucella bombylans and Volucella bombylans subsp. plumata
At first glance you might think these two hoverflies were bumblebees, and that’s exactly what they want you to think – or, rather, what they want bumblebees to think, because they don’t want to be caught out when sneaking in to lay their eggs in the nests of the bumblebees they mimic (which are the Red-tailed bumblebee Bombus lapidarius and the White-tailed bumblebee Bombus lucorum respectively).

190601 3 helophilus pendulus
190601 4 chrysotoxum bicinctum

Helophilus pendulus and Chrysotoxum bicinctum
Do you see why the hoverfly on the left is known as The Footballer? I’m not sure which football team his colourful markings are meant to represent – perhaps Helophilus pendulus has its own team. Its distinctive bands of bright yellow make Chrysotoxum bicinctum one of the easier hoverflies to identify.

190601 5 Xanthogramma pedissequum
190601 6 episyrphus balteatus

Xanthogramma pedissequum and Episyrphus balteatus
Xanthogramma pedissequum is another hoverfly with reasonably easy to identify markings – believe me, not all hoverflies are so easy! And with its rich orange colouring, Episyrphus balteatus looks almost edible, which is probably why it’s called the Marmalade hoverfly.

#365DaysWild, British insects, bumblebee, flies, hoverfly, insects, ladybird

I only managed to grab an hour’s walk today, once again dodging the rain showers that have been rolling in throughout the day. I thought I might blog about the wild garlic that’s covering every inch of the wilder areas in Penarth’s Alexandra Park but decided it would be better to wait until the flowers are at their peak as that would make for better photos. Then, as I was checking out the garlic and taking a few shots, my eye was caught by the number of insects sitting on their leaves, basking in the fleeting patches of sunshine, braving the weather on this mostly grey wet day. So here they are …
