Hawk Moths and More
/More moths caught at the weekend, including Small and Large elephant Hawk Moths and Cloaked Minor, another new species.
It wasn’t warm, but at least there was no rain and it wasn’t blowing a gale, so I was able to put out the moth trap for the first time in a few weeks. This year it seems you have to take your chances when they arrive. It was not a great haul of moths, but a couple of new species. Muslin moth (Diaphora mendica) is a May flier, there were four of these grey/brown males in the trap, but none of the white coloured females. The Puss Moth (Cerura vinula) also flies in one generation from May-July - I have found it’s impressive-looking caterpillars around the village, but not in the garden. Other trapped species were the Spectacle (Abrostola tripartita) caught in the moth trap, and a Cinnabar Moth (Tyria jacobaeae), caught in a nearby spider’s web.
Okay, it’s not quite November, but moth trapping this week, after a small gap, we had some new autumnal species.
First of the new species is the November Moth itself (Epirrita dilutata agg.), actually one of 3 very similar & closely-related species flying at this time of year, the others being the Pale November and Autumnal Moths, which in most cases require dissection to definitively identify. These moths fly now, laying eggs in the leaf buds of various deciduous trees, which duly hatch the next summer. The Beaded Chestnut (Agrochola lychnidis) also flies a single generation at this time of the year. The larvae live in rough grass, with the adults attracted to Ivy blossom. The second generation of the Grey Pine Carpet (Thera obeliscata) is another September-October moth.
The other moths caught included Turnip Moth (Agrotis segetum), a Silver Y Moth (Autographa gamma) and a couple of Light Brown Apple Moths (Epiphyas postvittana). The latter species is an accidental introduction all the way from Australia, which since arriving in Cornwall in 1930’s has expanded its range to become a common species in much of UK.
Getting a moth trap has been a game-changer in terms of adding new species to my list this summer - also a lot of fun. I brought up my 700th species in some style with a bevy of beautiful moths this morning after a perfect warm & still September night.
There are some more moths from earlier in the week, pushing my garden list closer to 700 species. The Swallow-tailed Moth (Ourapteryx sambucaria) was a particularly beautiful one; also quite a late record for this species, which is commoner in July.
The Gold Triangle moth (Hypsopygia costalis) has two postures, this one with its wings splayed out and tail in the air and a more normal moth-like v-shape. It’s larvae live in dried vegetation, like hay stacks or my neighbour’s thatched roof. The other two moths are also typical for the season; the Pale Mottled Willow’s (Paradrina clavipalpis) larvae live in cereal grain, while those of the Rosy Rustic’s (Hydraecia micacea) live underground mostly in the roots of plants of the dock family.
After a bit of a break during the holidays, it was good to get my moth trap back out and see what was about. Among the Large Yellow Underwings there were a few new species. This Black Rustic and a couple of prettily veined Lunar Underwings were my favourites. I nearly missed the Small Dusty Wave altogether as it is more or less perfectly camouflaged against egg box grey.
It’s taken me a few days to identify all the moths I caught on Friday night, with 15 new species added to the list. There were many moths in the trap and even more all around on the house wall and surrounding plants. Some of the highlights below. Without the moth trap you only see a fraction of what is out there.
For a change last night I was trapping in my Dad’s garden in Winchcombe. He’s always reminiscing about how many more insects there were back in the old days, and he’s for sure correct. Even so it was great to catch a pretty decent selection of moths, several that i didn’t yet catch at my place. I took some photos of a few of the more colourful ones and ones I didn’t recognise, including a Marbled Green (Nyctobrya muralis) which seems pretty unusual this far from the coast. A rather impressive Sexton Beetle had dropped into the trap; this is a carrion beetle that searches out dead small animals and raises its larvae in a burrow under the corpse.
Monday night was my best night’s trapping for quite some time, including five new species. The Brimstone Moth was not new, but the light drew in several of these and I didn’t get a photo the previous time I recorded them. Scalloped Oak, Single-dotted Wave, Shuttle-shaped Dart, Straw Underwing and Turnip Moth were all new, reflecting a shift in the season and new generations of these moths appearing. I caught several Shuttle-shape Darts, Straw Underwings and also Riband Waves, plus individuals of several other species.
No rain last night, so the moth trap was out and catching a fair number of moths, the Heart & Dart being the most numerous, with a couple each of Vine’s Rustic and Uncertain moths. With these there were three new species: a Bright-line Brown-eye (Lacanobia oleracea), a twig-like Flame moth ( Axylia putris) and a Barred Straw (Gandaritis pyraliata). The Barred Straw is an unusual looking moth as it rests with its fore-wings completely covering its hind-wings, and in this case fluttered off before (unfortunately) I could get a better photo.
After a couple of fruitful trapping evenings I had a bit of a backlog of photos and a few identification challenges I was still working on. I’m impressed how many moths I’ve caught, and the variety of species - I had no idea there were so many around. I particularly love the birch twig imitating Bull Tip and the pattern on the Grey Dagger, neither of which I’ve ever seen before. As the weather has turned a little wet and it looks like it will be windier too I’ll give it a rest until the weekend and see if there’s anything else around I should take notice of.
My moth trap arrived, and even though the weather was not great - cold and quite windy - what the Hell, I had to give it a go. Not many species caught, but at least on the plus side I have to spend the whole day identifying moths! A single Heart & Club (Agrotis clavis) was the sole catch on Friday night, but it was a new species - one that is apparently very readily attracted to light. Saturday night was still and a little warmer after some rain, so I woke up to a moth trap with a dozen or so moths in it, including White and Buff Ermines, Setaceous Hebrew Character, an Uncertain, Willow Beauty, Riband Wave, Spectacle, Shoulder-striped Wainscot, Olive Pearl (Udea olivalis), Barred Marble (Celypha striana) and three more Heart & Club moths. Several of those caught were new species for my garden list, and I’m very happy with my new purchase.
Passionate about nature, based in Gloucestershire UK; this site is about creating a wildlife friendly family garden and exploring the diversity of animal & plant species that share it with us.
As a nature lover and wildlife gardener I started wondering about the biodiversity in my backyard and just how many species from plants to insects to birds to mammals might live in or visit it.
Much of the wildlife in my small, village garden has been present right under my nose for years without my really appreciating it, so on the way I am learning a lot about different species and how to make a wildlife-friendly environment for them; also getting engaged more in conservation activities around Gloucestershire, Worcestershire and the Cotswolds.
My garden species tally started from zero on June 1st 2018, the target was 1000 species, which I eventually hit in June 2024. But there’s still plenty to see and learn about.
I'm very interested in your comments & advice: whether it's about the blog, some help with identification or just how to make my own little Eden better for wildlife. So please leave a comment or drop me a line if you feel like it!
