Moth Trapping 19 July pt 2

/

Here’s a mixed bag of other moths and insects caught last week. At this time there is a large variety of creatures on the wing at night.

Moth Trapping 19 July

/

I’m still catching new species in my moth trap; here’s three from 19 July which I’ve just finally got time to post. Leptocerus tineiformis is a small caddisfly with very long antennae that is found around ponds. Green Arches (Anaplectoides prasina) is usually rather greener than this individual; it flies in June-July and its food-plants are bilberry, honeysuckle and knot grass. Brown Moss Moth (Bryotropha terrella) is also single-brooded frequenting grassy areas and flying throughout the summer.

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.

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.

Small Magpie, Buff Ermine, Vine's Rustic

/

A dry and still night, but too cold for many moths unfortunately. These three are species I didn’t post previously. The two Small Magpies I caught were the first of the season for this macro-sized micro moth. Small Magpie has a long flight season through to September, its food-plants are nettled & woundwort. Buff Ermine is another common moth (four in the trap this morning) flying from May-July; food-plant nettles, but also a variety of other herbaceous plants including birch & honeysuckle. Vine’s Rustic has 2 generations, one now and a larger one in the late summer when it is for a period one of the most numerous macros. It’s caterpillars eat plantains and docks.

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.

Plum Tortrix & Shears

/

Not too many moths this morning, but two new species; neither of them particularly unusual, but both only have a relatively short flight season in May/June. Plus Tortrix is one of those orchard tortrix species that, at rest, look a bit like a bird poo. The Shears is named for the black mark on its wing that looks a bit like old-fashioned shears used for shearing sheep. Two new moth species and I’m closing in on my 1000 species target.

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.

Chocolate Tip (Clostera curtula, #986)

/

As a new species for the garden, Chocolate Tip moth (Clostera curtula) was the highlight, but there were also some other beautiful moths in and around the trap this morning. With some warmer weather we were up to 20 types of moth today. In England, Chocolate Tip has two generations, one now and another in Aug/Sept; it is a woodland species preferring Poplar, Aspen & Sallows. It’s not rare, but seems less frequently encountered than the other moths caught today.

#985 Nut-tree Tussock (Colocasia coryli)

/

The small collection of moths in the moth trap this morning, included this Nut-tree Tussock Moth, which is a new species for my list. This moth’s food-plants are trees such as hazel and beech. It flies in 2 generations, in April-June and July-September.

Other moths included four Sliver Cloud moths, which are a local speciality with a small range in UK centred on the Severn & Wye valleys, and a few other typical Spring fliers.

Pinion-spotted Pug (Eupithecia insigniata)

/

Finally, the first outing this your for my moth trap. The star of the show was a Pinion-spotted Pug (Eupithecia insigniata, #982), top left. This is not a common moth, usually only a few caught per year in Glos, so the most unusual moth I’ve caught in a while and a great start for the year. Otherwise there were not many moths flying, but a Pebble Prominent (Notodonta ziczac) is always welcome. The small grey cranefly, maybe a Monophilus species, was likely a new species, but not sure if I’ll ever confirm any ID for it.
