Bank Holiday Moths
/A fairly typical selection of moths for the end of May. 17 moths of 15 species recorded, which is average for the time of year.
Moths - 11 May
/Been busy, so a small delay adding some photos from last week. These are fairly typical moths for May-June. plus the first Cockchafer of the year.
#1017 Mullein Moth (Cucullia verbasci)
/After a mini heatwave for the time of year. I put out my moth trap on one of the colder evenings and din’t catch much. But one of the few was a Mullein Moth (Cucullia verbasci), a moth that files in one generation in April-May. Its conspicuously-marked caterpillars are found on Buddleia (and of course, Mullein).
Shuttle-shaped Dart (Agrotis puta) is the most frequently caught moth in this season, with a second generation in Aug-Sept. This week I caught several - all males, like the one pictured (females are quite differently coloured)..
Black Sexton Beetle (Nicrophorus humator)
/These sexton beetles are a regular catch in the moth trap during March-April. It’s always good to catch a big beetle! The adults overwinter emerging in the Spring. They tend to fly at night, searching by smell for dead birds or mammals, where the female lays her eggs and on which the larvae subsequently feed.
Quakers & Early Spring Moths
/After some warmer days, this was the first outing in 2025 for my moth trap, catching some typical moths for mid-March. All of these moths fly for a couple of months in a single generation in the early Spring.
A New Gnat
/Moths are getting a bit thin on the ground, but normally I’s expect more than just a single Light Brown Apple Moth by the trap in the morning. There were a lot of gnats attracted to the light thpough, including Winter Gnats and a Sylvicola species, which I believe is Window Gnat. The latter turns out to be a new species for the garden, as previously I only noticed Clear-tipped Window Gnat (Sylvicola punctatus), whereas last night’s has grey wing-tips if you look close enough. This is a common species though, that can be found all year round.
Frosted Orange, Blair's Should Knot & Pale Mottled Willow
/As we had a nice dry night on Friday, I was able to put out the moth trap. I caught nine species, including this trio - all of them fairly typical for the time of year. Frosted Orange (Gortyna flavago) flies during Aug-Sept, it’s larvae live inside the stems of thistle plants. Blair's Shoulder-knot (Lithophane leautieri) is found around Cypress trees and flies a bit later - Oct-Nov. It is a non-native species first recorded in UK in 1951, but now widespread in gardens across most of England. Pale Mottled Willow (Caradrina clavipalpis) flies from July-September; its larvae are found on grain of cereal crops, including those that have been harvested.
Blunderwings
/Out of 38 moths this morning, 19 were Large Yellow Underwing (Noctua pronuba) - fairly typical for the season. These are common Autumn moths, colloquially known as “blunderwings” as they fly off clumsily when disturbed from their daytime resting spots. The sandy-coloured Broad-bordered Yellow Underwing (Noctua fimbriata) is a similar size also with a yellow hind-wing, but this time with a broader black band around the margin. Of the other moths in and around the moth trap nine were Setaceous Hebrew Character (Xestia c-nigrum).
Friday's Stars
/Three exotic-looking moths from the other day… it’s always a thrill to find beautiful creatures like these when you check the light trap in the morning.
Three New Moths
/I had a good haul of moths in and around the moth trap yesterday morning - the biggest catch of the year so far - which included these three new species.
The Sycamore is similar to the Poplar Grey, which seems more common round here - but prefers Sycamore and Field Maple trees, rather than Poplars and Aspens.
The Marsh Pearl or Fenland Pearl (Anania perlucidalis), told from the similar Mother of Pearl moth by the two dark dots on the wings, seems not that common in Gloucestershire, away from its main range in East Anglia.
Limnephilus marmoratus (#1002)
/A couple of non-moths in the moth trap yesterday, including a new caddisfly, Limnephilus marmoratus. This caddisfly, distinguishable by its boldly marked wings, lives around ponds and commonly comes to light. The Ophion ichneumon wasp (hard to identify to species level) is also nocturnal and commonly found in moth traps - this family of wasps are parasitoids of noctuid moths.
From the Thatch
/Gold Triangle (Hypsopygia costalis) and yesterday’s other new moth, Double-striped Tabby (Hypsopygia glaucinalis), are closely related species both of whose larvae live in dry, dead vegetable matter, such as straw or birds nests. Given this, I suspect that they might originate from my neighbour’s thatched roof. Both species fly in July-August and are mostly found in Southern England.
1000 Species: Large Emerald (Geometra papilionaria)
/This morning I achieved my “1000 species” goal from when I started this project back on 1st June 2018, with a brace of new moths. The first of these was a Large Emerald, which with a wingspan of 50-60 mm is our biggest UK all-green Emerald moth. It is a woodland species associated with birch and hazel with a single flight period peaking in July.
#1000 Large Emerald (Geometra papilionaria)
Midsummer Moths
/Here’s a few more moths from the other night: my first Riband Waves of the season and this nicely green Green Pug. There are more micros now too, including my first grass moths and these two fruit tree species: Bramble Shoot Moth and Codling Moth - the former as you might guess eats bramble leaves, while the larvae of the latter grow inside the cores of apples and other hard fruit like quinces & pears.
#999 Green Oak Tortrix (Tortrix viridana)
/This pretty, pea-green moth is a fairly common woodland species flying in May-July. With a preference for Oaks, though it will also lay eggs in other deciduous trees, its caterpillars feed from within a rolled up leaf. It can be a pest, sometimes completely defoliating trees. A new species for my garden it brings my total to 999.
Light Emerald, Cinnabar & Green Pug
/Three handsome, but quite different moths. Cinnabar Moth is very distinctive species, whose yellow & black striped caterpillars are found (often in numbers) on ragwort plants. Green Pug is a summer species which lays eggs in the blossom of fruit trees such as apple or pear, while Light emerald is a woodland moth found on various trees and hedgerow plants with two generations in Spring & Summer.
Sunday Moths
/Here’s a selection of other moths caught on Sunday morning. Poplar Hawk-moth was the first hawk-moth of the year; the others also firsts for the year as spring moves into summer.
Three New Moths
/A varied selection of moths this morning, with surprisingly three new species. All three of these moths fly only for one season, during May/June. The Lychnis is named after the latin name of its food plant, Rose Campion (Lychnis coronaria). Campions are also the food-plant of Sandy Carpet, while the larvae of Rustic Shoulder-knot feed on grasses.
300 Moths
/I’m getting quite close to my 1000 species target, but on the way recorded my 300th moth this weekend, adding May Highflyer, Grass Rivulet and Oak Knot-horn.
Grass Rivulet is a species of open grassland, it’s larval food-plant being Yellow Rattle. I do have that in my mini wildflower meadow; which as it’s only about 2 square metres maybe shows that every little really does help! Oak Knot-horn is a micro usually associated with Oak trees; it’s a common enough species, but usually flies in June-July.
Flying Carpet Moths
/Lots of carpet moths on Sunday morning, including different forms of Common Marbled Carpet (Dysstroma truncata) and one new species, May Highflyer (Hydriomena impluviata, #988). May Highflyer has one generation flying from May-June and is usually around Alders - a tree I do not have nearby, to my knowledge. The white bar across the centre of the wings helps identify this species from other carpet moths.
