Three little shieldbugs

When the sun’s shining (which, admittedly, hasn’t been very often in the last couple of weeks), the patches of bramble and low scrub seem to be full of shieldbugs of various sizes and stages, basking in the welcome warmth. Two I’ve seen recently have been new to me:

Although I’ve seen Bronze shieldbugs (Troilus luridus) before, I’ve not seen this particular variation, which is a mid instar, halfway between egg and adult.

230801 Eurygaster testudinaria tortoise final instar

You might remember the lesson I learnt back in July 2022 (Blackberries, yum!) to always check a Blackberry before putting it in my mouth. Well, that held true again recently: I was about to pluck this luscious-looking berry when I noticed its occupant. This little critter is the final instar of the Tortoise shieldbug (Eurygaster testudinaria), a new shieldbug for me.

230801 red-legged shieldbug

And this last bug is not new at all but I liked the way it was posing, and the fact that I was able to get some shots of the lovely speckling on its belly. This is an adult Red-legged shieldbug (Pentatoma rufipes).

Little Gorse shieldbugs

I’ve blogged about Gorse shieldbugs (Piezodorus lituratus) before, in particular the adult bugs and their amazing little barrel-shaped eggs (in A bug and its eggs, April 2022) but I’ve only once before seen one of the intermediate stages of the nymphs between egg and adult (a second instar – see A shieldbug selection, September 2021). Until last week, that is. And these Gorse shieldbugs, of various instars, were actually grazing on Broom rather than Gorse. (The British Bugs website has both photographs and a chart of the diversely coloured nymphs, if you’re interested in more information.)

Hairy in hiding

I’m not sure what this Hairy shieldbug was doing – well, actually there were two of them, and they’d both decided they were going to play hide and seek under the fluffy umbrella of a Dandelion seedhead. Crazy, but cute!

Lurking beneath

British bugs, British shieldbugs, Elasmucha grisea, leaf-turning, Parent bug

This is my favourite time of year for leaf turning, not only because it’s the best time of year to search for leafmines but also because you never know what you might find lurking beneath. In this instance, a rosy red Parent bug (Elasmucha grisea), which overwinters as an adult bug, was hiding away beneath the leaves in a well-vegetated spot.

Final instar Hawthorn shieldbugs

My walk of the fields at Cosmeston Lakes Country Park hadn’t turned up any migrating birds so I was having a poke around some trees before heading home when I found these two huddling together amongst the leaves. They’re Hawthorn shieldbug nymphs (Acanthosoma haemorrhoidale) in their fifth and final form (instar) before they become adults. (You can see the various instars on the superb British Bugs website.)

A bug and its eggs

The sunshine yellow flowers of gorse always draw my eye and I can seldom resist a quick sniff of their delicious scent (does gorse smell of coconuts or do coconuts smell like gorse?). This time, as I drew close to the flowers, I noticed a Gorse shieldbug (Piezodorus lituratus) enjoying the Spring sunshine.

And then, of course, I had to have a quick search for more. I didn’t spot any further adult bugs but I did find two lots of their distinctive black-and-white barrel-shaped eggs. Apparently, the eggs hatch within a week so I’ll have to revisit this plant soon to see if I can find the nymphs.

A huddle of Parent bugs

Seeing this huddle of final instar nymphs of the Parent bug (Elasmucha grisea) made my day!

I wasn’t sure what they were at first but, in case you’re not aware of it, the British Bugs website hosts a brilliant selection of photographs of all stages of British bugs, so a scroll through the shieldbug gallery quickly provided me with their identification. The website is particularly helpful for the less recognisable early instars of insects like shieldbugs.

Do you have a favourite bug? I think the shieldbug is mine. Always cute, often comical, reasonably easy to identify – what’s not to love?

Shieldbugs on gorse

I had expected to find Gorse shieldbugs on these glowing gorse bushes (the clue’s in the name) but, in fact, the most numerous were the Hairy shieldbugs (of which there must have been at least 20).

The Gorse shieldbug (Piezodorus lituratus) (above left) looks very like a Common green shieldbug but its red antennae are a distinctive identification feature. The Hairy shieldbug (Dolycoris baccarum) (above right, and below) is a much more colourful character, a stylish combination of purple-brown and green, and it also has distinctive antennae, this time three white bands on a black base.

You wouldn’t think an insect that looks like it’s wearing armour (hence ‘shield’ bug) could be hairy but the Hairy shieldbug (Dolycoris baccarum) is living proof. It’s difficult to see the hairs when you’re viewing them in full sunshine, as their shield-shaped backs are quite shiny, but if you can get a close view in a shady setting, you can see the hairs on their legs and, in my photo below, along the top of the shield.

I found at least 20, probably more, of these handsome creatures in the scrub alongside a seldom-walked local path, and will be keeping an eye on this area to see if I can spot their offspring in the coming months, as it’s always interesting to see the different stages of growth. You can see images of these different instars, not only for the Hairy shieldbug but also for all the other shieldbug species, on the excellent British Bugs website.
