The number and variety of invertebrates that are now out and about is gradually increasing, though seeing them depends on reasonably warm, sunny days, which are still very much intermittent here in south Wales. When the sun does shine though, shieldbugs can be seen basking on the trees of shrubs and wildflowers, and I’ve now managed to spot these three different species.

Hairy shieldbug (Dolycoris baccarum)

Hawthorn shieldbug (Acanthosoma haemorrhoidale)

And Green shieldbug (sometimes called Common green shieldbug, Palomena prasina). Both of the above are Green shieldbugs but this species changes to a bronze colour before winter hibernation and takes a little time to change back to its usual green hue come the spring.

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!

The shallow bowl shape of the leaves of Winter heliotrope were perfect for the bugs enjoying Monday’s warm spring sunshine. In one small sheltered area I found several Common green shieldbugs (Palomena prasina) . . .

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.

I imagine this little guy was trying to shelter on this building wall, attempting, as I was, to avoid the worst of the wind and rain. At least it could easily fly off into the nearby bushes, whereas I had a 20-minute uphill walk to get home. Oh, and in case you don’t know, this is a Hairy shieldbug – you can read more about these handsome creatures in my post Hairy shieldbugs, April 2020.

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.

There’s a little track I often walk down, or up, between my home and Penarth Marina, that’s not been touched by the Council’s destructive strimmers (so far), so it’s a great place to look for wildflowers and critters, and it can take me 30 minutes or more to walk its 100 metres.

When I walked this way the other day, I came across this little Green shieldbug (Palomena prasina). Just look at that innocent-looking face … but don’t be fooled. It was probably the only one of maybe 30 Green shieldbugs I saw that was on its own – all the others were working on ensuring the continuation of their species.

Even the Hairy shieldbugs (Dolycoris baccarum) I found (only 3 of those) were at it! Given all the bad news we hear these days about declining insect populations, I hope this means the shieldbugs are doing okay.
