No booming Bittern but …

British butterflies, butterfly, Comma, Comma butterfly

A 10 minute walk to my nearest train station; a 15 minute train ride to central Cardiff; an 8 minute walk to the correct bus stop; a 20 minute bus ride; a 10 minute walk to Parc Tredelerch (plus some waiting time in between those various journeys) and all in the hope of hearing a Bittern booming out its love call from the reedbeds. Did it boom? No, it did not. But the sun was shining, I got plenty of exercise walking around and round the various trails in the park, and, a beautiful bonus, I saw my first Comma butterfly for 2026.

And wouldn’t you know it? That darn Bittern boomed again early the following morning. It obviously didn’t like the look of me!

Four weeks early

British butterflies, butterfly, Speckled wood

Last Monday, 2 March, I was delighted but also rather astounded to see my first Speckled wood butterfly for 2026 – astounded because this is four weeks earlier than I saw the first of this species in 2024 and 2025. This is nowhere near a UK record though, as the first sighting I found on iRecord was reported at Old Colwyn, in Denbighshire, on 21 February, and there are two other February records in the system: in Cornwall on 22 February and in north Essex on the 25th. The second of March was obviously a warm day across Britain as mine was one of several sightings recorded from various locations on that day. (Of course, these are only the sightings that have been recorded; other Speckled wood butterflies may have been seen but most people don’t record their sightings.)

Three shieldbug species

Acanthosoma haemorrhoidale, British shieldbugs, Common Green Shieldbug, Dolycoris baccarum, Green shieldbug, Hairy shieldbug, Hawthorn shieldbug, Palomena prasina, shieldbug

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.

As the day and night temperatures begin to rise and we start to enjoy occasional sunny days, the number of flying insects continues to rise. Spring has only just begun but I’ve already logged two species of bumblebee and three hoverfly species on the wing. They are …

Breaking news!

Brimstone, Brimstone butterfly, British butterflies, butterfly, spring butterflies

I’m interrupting the series of blogs on sightings from last week’s mini break in Dorset to bring the best possible news … we have butterflies!!!

Yesterday the temperature in Cardiff reached around 14ºC, warm enough for butterflies to emerge, and, during a walk around Cardiff Bay, I saw my first four Brimstones of the year, two at the wetlands reserve and two more – the two shown here – at the adjacent Hamadryad Park. I find it difficult to express how I feel when I see butterflies in flight; their magic makes my heart sing. If you haven’t seen your first butterflies yet, I hope you do soon!

My first moth of the year

British moths, Early moth, moth, Theria primaria

Those moth-ers who run nightly moth traps have been reporting, on social media and despite the often detrimental weather, that small numbers of moths have begun appearing in their traps during the past couple of weeks. As I don’t trap, I’ve just been keeping an eye out in the places I sometimes see moths, usually on walls near where outside lights are on at night. And, finally, last Thursday, I spotted my first moth of the year, a new species for me, an Early moth (Theria primaria). As you might guess from its name, this is one of the first species to be seen each year, appearing in January and February. Though the UK Moths website says it’s usually found in woodland margins and hedgerows, this one was on the panelling around a building site, though the opposite side of the path is full of trees and scrub.

Beetle: Athous bicolor

Athous bicolor, beetle, British beetles

This is the last of my new invertebrate finds from 2025, and it may or may not be the beetle Athous bicolor, found in shrubs around the edge of a local recreation field last July.

My specimen appears to have the features described on the Naturespot website – ‘quite an elongated species’, ‘elytra are brown in colour with ridges and pits running down their length’, ‘pronotum is slightly darker’, ‘legs and antennae are unicolourous with the rest of the insect and the antennae are very long’ – but their identification difficulty indicator is red, meaning the features are not as clear as the description indicates and/or there are other very similar species.

Still, it was an interesting beetle to find and photograph. This species is generally found in grassy, shrubby areas, sometimes feeding on umbellifer flowers or just sitting in the sun on long grass stems. Good luck if you find one and want to identify it!

Bug: Capsus ater

This is another of my new bug finds from last year, found while leaf-turning wildflowers and scrub along a path in a wild area of a local park. Meet Capsus ater, from the Miridae family of British plant bugs.

I found this little fellow in early June, when the adults first appear; they can be seen from June right through till September. I was lucky to spot it higher up in the vegetation as they usually feed low down on plant stems, according to the British Bugs website.

Weevil: Sitona species

Here’s another of last year’s new finds, which I think is a Sitona lineatus weevil but that hasn’t yet been confirmed, hence today’s blog title of Sitona species. I found this little creature on the local park railings at the end of April last year but had been holding off posting about it pending verification, or not. It seems, however, that no one is currently checking weevil records.

If this is, in fact, Sitona lineatus, its common name is Pea leaf weevil, and the Naturespot website says it is the most common of the Sitona species. Although the website provides a list of features to look for to identify this species – straight sides to the wing cases, moderately bulging eyes, alternating light and dark longitudinal stripes, etc., some of those features, like ‘flat bristles on the front half of the wing cases and slightly raised in the rear half’, are shared by other Sitona species. Naturespot reports that ‘dissection is often necessary to confirm’ which species you have found, and I prefer to leave all the lovely little creatures I find alive and plodding along.

Bug: Stenotus binotatus

I’ve just realised that I have a few bug finds from last year that I haven’t yet shared, which is actually something of a relief, as I’ve been struggling to find creatures to share with you all (apart from my beloved birds – there are always birds!). So, here is a plant bug Stenotus binotatus, which I found in a local field back in June. The adults can be seen between June and September, and can be found in grasslands, where they feed on the flowers of the grasses that grow there.
