Bug: Stictopleurus species

Tags

, , ,

There’s one more bug I’ve spotted while out surveying all the Common fleabane flowers in my local vicinity that I want to talk about here. I didn’t include it in the more general bugs blog, On Common Fleabane: bugs and crickets, as I was hoping to get confirmation of its exact identity. It seems now that’s unlikely to happen and I will shortly explain why. But first, let me introduce Stictopleurus, of which I found both an adult (first photo) and a nymph (second photo).

There are only two Stictopleurus species in Britain, S. punctatonervosus and S. abutilon, but, like so many creatures, the two are not easy to distinguish one from the other. The British Bugs website explains:

The two species are very similar and best separated with reference to the fine detail of the pronotum. In S. abutilon, the dark marks behind the anterior margin take the form of two full circles (half circles in S. punctatonervosus). There is also a narrow impunctate band in front of these markings. Note that these characters are not always easy to discern [my emphasis].

That sounds relatively easy, right? The website pages for the two species even have sketches of those magic circles. But that last sentence is crucial: ‘these characters are not always easy to discern’. I fiddled with my clearest photo in Photoshop to try to see those full or half circles more clearly, and I think I see half circles (so Stictopleurus punctatonervosus). What do you think?

On Common fleabane: bees and flies

As I wrote in my blog last Sunday about the life-saving benefits to wildlife of Drought-tolerant Common fleabane, the sheer number of insects I’ve seen feeding on fleabane gives me hope for their survival of this summer’s heat and drought. And, fortunately, many locations in the UK have had some rain this week, easing the situation a little for both wildlife and humans. This final blog includes some of the bees and flies I’ve seen on Common fleabane. However, as I’m not very skilled at identifying either of these families, I’ve excluded several I wasn’t able to name. Bees first.

A worker Buff-tailed bumblebee (Bombus terrestris), out foraging for pollen to take home to its family, all the offspring of a single queen who mated at the end of last summer, hibernated through the winter and began a new family in the spring. That life cycle will soon begin again.

A Common carder bumblebee (Bombus pascuorum), hard at work just like its Buff-tailed cousin.

A Honey bee (Apis mellifera) – I think we all know about Honey bees, their hives, their delicious product.

And now the flies I’ve been able to identify. Firstly, the very distinctive Red-sided parasite fly (Eriothrix rufomaculata). I spotted a few of these, which appeared to be feeding on the flowers but may also have been looking for moth larvae to parasitise.

This splendid metallic green fly is Lucilia sericata. Although there are several similar green flies, by zooming in on my image I was able to confirm that this one has ‘one anterior-dorsal bristle on the mid-tibia’, which is one of the main identification features for this species.

On Common fleabane: spiders and wasps

This is the penultimate blog about the creatures I’ve been seeing feeding on Drought-tolerant Common fleabane, aiding their survival during this summer of record-breaking heatwaves and drought. Today’s post features both spiders and wasps, starting with the spiders.

This first little cutie is a Flower crab spider, Misumena vatia, one of several of these sneaky creatures I found, not actually feeding on the fleabane but lurking around the edges of the flowers, ready to pounce on anything unsuspecting and tasty looking that was unfortunate enough to perch too close.

Nursery web spider (Pisaura mirabilis), quite a small specimen so perhaps one of this year’s brood.

Xysticus lanio is another crab spider, one that’s actually quite difficult to identify so I’m not 100% sure of this one.

These last two are Ichneumon wasps, not identifiable from these images but possibly from the subfamily Pimplinae. The one in the second photo is munching on a very tiny creature. There were also lots of common wasp species but they rarely stopped still so I didn’t manage any photos of them on flowers.

On Common fleabane: bugs and crickets

The subjects of today’s blog about those insects managing to survive this over-heated summer by feeding on Drought-tolerant Common fleabane are bugs, and two examples of one cricket species, because I managed to find both male and female. Let’s begin with bugs …

Two Lucerne bugs (Adelphocoris lineolatus), pretty little things but both trying to hide from me.

I actually saw quite a few Common froghoppers (Philaenus spumarius), and in several of their wonderful variety of brown-and-cream pattern variations.

Clad in its brown armour-like skin and looking ready for a fight, a Dock bug (Coreus marginatus).

An adult Hairy shieldbug (Dolycoris baccarum). (I’ve found quite a lot of nymphs of this species recently and feel they deserve their own blog – you’ll see why soon.)

And now for the crickets. These are Long-winged cone-heads (Conocephalus fuscus), a type of bush-cricket. I’ve just realised that this species has only featured on this blog once before, in July 2020, when I included a photo of a nymph in the post 202/366 More misc minis. The first photo shows a female, though, unfortunately, her impressive ovipositor is mostly obscured; the second image is the male, with a much smaller appendage.

On Common fleabane: hoverflies

Here’s the second of my more general blogs about the insects I’ve been finding in the past week that are managing to survive the season’s destructive heatwaves and drought by feeding on the flowers of Drought-tolerant Common fleabane. Today we have some of the many species of hoverflies I’ve noticed and managed to photograph.

First up, two different Eristalis species – I included the first image just because I liked it.

Episyrphus balteatus, aka Marmalade hoverfly, one I’m sure most people will have seen.

The Footballer, Helophilus pendulus, which gets its common name from the resemblance of its stripy thorax to a football strip.

The Sphaerophoria species of hoverfly were probably the most common in my favourite wildflower field, but they can be tricky to name precisely.

There were also a lot of these Syritta pipiens, but they were very wary of me getting close enough for photos so I was pleased to snap this one.

On Common fleabane: Lepidoptera

As I wrote in Sunday’s blog about Drought-tolerant Common fleabane, the number of insects I’ve been seeing feeding on these plants gives me hope for their survival of this summer’s heat and drought. These are some of the Lepidoptera species I’ve seen, starting with the butterflies.

As well as these Common blue, Small white, Clouded yellow f. helice (my first of this pale colouration this year), and Brown argus, I’ve also spotted Meadow brown on the local fleabane flowers.

Next, the moths, both larvae and adults. The first is a caterpillar of one of the Pug moths (Eupithecia sp.), and the second, hiding in its self-made case, is Coleophora conyzae, a new species for me and a rare moth in Wales, with only 15 records to date.

The dark moth is Apodia bifractella, another that was new to me, though a moth that’s listed as common on the UK Moths website (n.b. it seems to have had a very recent name change to Apodia martinii). The final moth is the stunning Common purple & gold (Pyrausta purpuralis) – I’ve seen several of these enjoying the nutrients provided by Common fleabane flowers.

Fruitfly: Myopites inulaedyssentericae

This was the second new species I found last Sunday when walking around a local wildflower field, staring intently at all the Common fleabane (Pulicaria dysenterica). Despite all that staring, I’m amazed I noticed these, as they’re tiny. But, having said that, I was checking out fleabane on today’s walk and found another of these at a different location – and that really did amaze me as there are only three records of these in the Welsh national biodiversity database. Perhaps their tiny size means they’re easily overlooked.

As the blog name indicates, these are fruitflies, of the species Myopites inulaedyssentericae, which is a bit of a mouthful so perhaps you’d prefer their common name of Fleabane gall-fly, so called because their larvae create galls inside Common fleabane flowers. They can be identified by the pattern on their wings, and are on the wing during July and August.

Leafhopper: Eupteryx melissae

Tags

Amongst the many creatures I found during this weekend’s intensive focus on Common fleabane at two local sites, two species were new to me, which was very exciting. This is the first, the leafhopper Eupteryx melissae, which I’m particularly delighted about as I haven’t found a new leafhopper species for quite a while and, as I’m sure you’ll agree, this one is a stunner.

According to the British Bugs website, there are two Eupteryx species that look very much alike, this one and E. decemnotata. The features to check are the markings on the top of the head, the vertex, and the top of the body, the pronotum. Eupteryx melissae has ‘three large more or less rounded spots on the vertex and six smaller spots along the anterior of the pronotum, with an irregularly-shaped greyish area behind this’, exactly as shown in the photo below.

I was a bit surprised to read that Eupteryx melissae has the common name Sage leafhopper, and is the most common leafhopper found on Sage, as this one was on the underside of a leaf of Common fleabane and there was definitely no Sage growing in the field. The British Bugs website says it also feeds on other members of the mint family, the Labiatae or Lamiaceae – the Wildflower Finder website has a handy list – but I’m struggling to think which of these were in yesterday’s field; there may have been some Selfheal and possibly Hedge woundwort.

Drought-tolerant Common fleabane

I’ve just been looking at the rainfall data for my area: 1mm on 2 July, 0.4mm on 17 July, 0.8mm on 25 July and a few very welcome showers on 4 August that seemed to have given us an accumulation of about 4mm, and that’s it for the last seven weeks. And, today, our fifth heatwave of the year has just ended, with temperatures dropping to the mid-20°s Celsius. It’s little wonder then that drought was officially declared for the whole of Wales at the end of July.

Nature is struggling, to say the least, but there are some plants that are remarkably drought and heat tolerant, and the one that I’m noticing most often during my walks is Common fleabane (Pulicaria dysenterica).

During today’s walk I revisited the wildflower meadow I featured here two Sundays ago, A meadow full of Painted ladies. All the gorgeous Knapweed that had attracted the Painted lady butterflies had gone to seed but the Common fleabane remained, as full of life and vibrant as two weeks ago. Though some flowers had gone over, buds were still opening on most plants.

Even better, that fleabane was feeding a lot of little creatures, from butterflies and a few moth species, to hoverflies, flies and bees, as well as various bugs, both adults and nymphs. It made me feel a little more hopeful that some of our wonderful wildlife will survive this difficult weather.

When I noticed yesterday how well the fleabane was surviving, I started taking photos of the creatures I was seeing on it, and I continued that theme today. During a series of blogs this week, I’ll share what I’ve found.

A local Linnet

It’s that time of year when the seeds of Herb Robert are ripe and ready for any passing seed-eating birds to harvest.

Pigeons, both Woodpigeons and feral, seem to quite enjoy them but it’s the local Linnets I see feasting on them most often.

These particular Herb Robert plants grow amongst the stones of the embankment of the River Ely where it flows in to Cardiff Bay, convenient for the small flock of Linnets that spend their lives around the Bay.
