Three shieldbug nymphs

I’ve found some nice nymphs of our various shieldbug species during recent walks so thought I’d share a few of them. The nymphs almost always look quite different to the adults of the same species; if you’re unsure which shieldbug or which stage (instar) of nymph you’ve found, the British Bugs website has a page full of excellent drawings showing the various instars of all the British shieldbug species.

As this was only my fourth ever sighting of this species, I was particularly pleased to spot this Bronze shieldbug nymph (Troilus luridus), though it would have been difficult to miss as its metallic colours sparkled in the sunshine.

To illustrate how much these bugs change as they grow, I’ve included two photos of Hawthorn shieldbug (Acanthosoma haemorrhoidale), the top image shows early instar nymphs and below that is a mid instar nymph.

It was just a couple of months ago that I saw my first Juniper shieldbug (Cyphostethus tristriatus) and I wrote then (Juniper shieldbug, 3 June) that I was intending to return to the site to look for more, adults and nymphs. I did, and I have; this is one of two nymphs I found recently, a bug that’s just a stunning as the adult, in my humble opinion.

Shieldbug eggs and hatchlings

Recent leaf-bothering has turned up several clutches of insect eggs, usually laid on the undersides of leaves. Most I can’t identify but these are two I can. I knew this first lot were shieldbug eggs but I wasn’t sure of the species. Luckily, an entomologist who follows me on Twitter was able to tell me that this clutch was laid by a Common green shieldbug (Palomena prasina) and, due to the greyish colour of the eggs, he could also tell that they had been parasitised, probably by a species of parasitic wasp.

As you can see, this second clutch of eggs had fared much better, escaping the wasp’s ovipositor to produce these tiny hatchlings. Despite their reddish colouring, these are also Common green shieldbugs; the nymphs will go through several changes of colour and patterning before they assume their final adult appearance.

Little Gorse shieldbugs

British shieldbugs, Gorse shieldbug, Gorse shieldbug instars, Piezodorus lituratus, shieldbug nymphs

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.)
