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?

And a selection of Common green shieldbugs

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.

As well as the cute little flower bug I found on Hedge woundwort (see yesterday’s post), on a nearby plant I also found this Woundwort shieldbug (Eysarcoris venustissimus), its jewel-like colours shining in the sunlight.
As the name implies, Hedge woundwort is one of the plants this bug’s larvae feed upon. Apparently, these shieldbugs were considered rare in the 19th century but their situation has improved and the adults can now be found year round in much of southern Britain.
