A bumblebee and its mimic

Though there was a cold nor’easterly wind blowing, occasional sunny periods brought out a few insects during my visit to Cardiff’s Grangemoor Park last Friday, and I was lucky enough to spot a couple of Buff-tailed bumblebee (Bombus terrestris) queens feeding on Blackthorn blossom.

Even better, on one tree I found one of Britain’s larger hoverflies, one that mimics bumblebees, a Large bearfly (Criorhina ranunculi), one that can often be seen in early Spring on the blossom of willows, Blackthorn and Wild cherry. This hoverfly’s tail end can be white, orange or red in colour (this one’s was reddish); to see these variations, and his superb images of this hoverfly, check out Steven Falk’s Flikr album.

Out they pop

Invertebrates in the winter: some warm sunshine in a sheltered spot and out they pop: my first hoverflies of the year, several species of fly, a couple of Honey bees and a queen Buff-tailed bumblebee.
I should probably add that these images were taken on Sunday, before freezing Baltic air came blasting in from the east, causing temperatures to plummet. I imagine these critters have all now taken shelter once more, in amongst dense vegetation like Ivy or within cosy holes in the earth.

Hoverfly larvae

It’s that time of year when, especially after rain, hoverfly larvae can be found washed off their leaves on to fence posts, railings and stones (e.g. gravestones), particularly under Sycamore trees. Twice in the past week I’ve checked the roadside railings of a local park and found several larvae each time, of three different species.

First, a little cannibalism. The first shot shows a Dasysyrphus species larva that has almost finished eating a larva of one of the Syrphus species of hoverfly. When I returned this way a couple of hours later, the Dasysyrphus sp. larva hadn’t moved far (image on the right) and almost looked like it was considering the snail as prey but I think that would be biting off more than it could chew!

This is just the second Epistrophe grossulariae I’ve seen so I was very pleased to spot it. If you’re wondering what it will grow in to, click this link.

Syrphus species larvae were the most abundant (as with many of these larvae, it’s almost impossible to identify them accurately unless they’re retained and breed through to adulthood). And, as a final treat (?), here’s a little video of one of those Syrphus larvae munching on an aphid (slightly gross but compelling viewing!).

A rat-tailed maggot

‘What fresh hell is she sharing with us now’, I sense you thinking. For me, though, this was Sunday’s star find, something I’ve wanted to find for ages. This is the larva of a Myathropa florea species of hoverfly that I found living in a sap run on a Sycamore tree. The ‘tail’ is actually its breathing tube, a bit like a long snorkel.

When I spotted it at the edge of a cleft in the Sycamore, I used a stick to move it gently out into the open a little more so I could get some photos. I expected to have to nudge it back but, as you can see in this short video, it turned itself around and slowly undulated itself back in to its home in the puddle of watery sap, leaf litter and insects. Now to find more maggots!

The mimics

You may have seen on social media and, indeed, be experiencing for yourself our ‘silent spring’, where the lamentably small numbers of invertebrates are causing grave concern. I have also found this – places where I would normally be seeing good numbers of bees, flies, butterflies and bugs are almost empty of life. So, I was even more pleased than usual last Monday when I spotted two Volucella bombylans hoverflies, one of each of the two colour variations, in a corner of a local field. These are bumblebee mimics, deliberately imitating bumble species so as to enter the nests of bumblebees to lay their eggs within.

Volucella bombylans var. plumata above mimics the White-tailed bumblebee (Bombus lucorum). I’ve included a photo of Bombus lucorum, above right, so you can see the two side by side. And, as you can see, the colouring of the second Volucella bombylans below is quite different. This is Volucella bombylans var. bombylans, which mimics the Red-tailed bumblebee (Bombus lapidarius) shown lower right. The mimicry isn’t perfect but it obviously works – if it didn’t, these hoverflies wouldn’t exist.

Meliscaeva auricollis

British hoverflies, hoverfly, Meliscaeva auricollis

In just a few days we’ve gone from sleet and snow to a high of 11ºc. We humans can easily change our clothes to suit the conditions but the see-sawing temperatures must be creating problems for the insect world.

230313 meliscaeva auricollis (1)

Some, like these Meliscaeva auricollis hoverflies, emerge from their winter hibernation when the temperatures start to rise, then get knocked sideways when the mercury plummets and the snow starts to fall. Hopefully, they’re able to find shelter from the icy blasts so they can re-emerge at a later date.

First hoverfly

British hoverflies, Eristalis pertinax, Eristalis tenax, hoverfly

During Monday’s walk along the local section of the Wales Coastal Path, I spotted my first hoverfly of the year, and immediately got the identification wrong. It seems that every winter I forget the basics for these creatures and have to refresh my memory over and over again (old age, or hoverfly blindness?).

230203 eristalis tenax (1)

In my defence, these are two very similar species but it took a friendly follower on Twitter to remind me that, for the hoverfly I found, the ‘feet are darker than E.[Eristalis] pertinax and it has a bendy rear tibia and hairy bands on its eyes so this is Eristalis tenax‘. (The ‘foot’ is the final segment of the leg.) To remind me, and help you, I’ve included comparison photos below – Eristalis tenax, he of the darker front feet, is on the left, and Eristalis pertinax, with the pale feet, is on the right.

The aphid munchers

Today’s focus is on one of the smaller things in life, specifically every gardener’s friend, one of the aphid munchers, the hoverfly larva.

In fact, not just one larva, but many, and from more than one species, feasting on aphid-infested Wild parsnip plants. The larvae in the photos above have been identified as being one of the Syrphus species of hoverfly, while those below, according to an expert, are probably Melangyna compositarum agg / umbelltarum. All would need rearing to adulthood for more precise identification.

It’s worth checking the stems, leaves, seedheads of plants with aphid infestations as hoverfly larvae are almost certain to be lurking there somewhere.

The big four

British hoverflies, hoverfly, Volucella bombylans, Volucella inanis, Volucella pellucens, Volucella species, Volucella zonaria

These are the big beasties of the hoverfly world, the bumblebee, wasp and hornet mimics. Though their size can be a little intimidating, they are all completely harmless to humans, and wonderful to watch going about their daily lives. There are actually five Volucella species in Britain – the woodland species Volucella inflata does occur locally (see A new hoverfly, June 2020) but I’ve not noticed one this year. The big four below are Volucella bombylans, Volucella pellucens (commonly known as the Great pied hoverfly, due to its colouring), Volucella inanis and Volucella zonaria – these are the two mostly easily confused with each other but the most obvious difference is the chestnut colouring of V. zonaria‘s thorax.

A little video slideshow of some of the hoverflies that have recently caught my eye, including one new species larva – always a treat to find these strange-looking aphid eaters.
