MACRO MOTHS

Dark Arches moth

Apamea monoglypha

The Dark Arches is another moth which comes in various shades of background wing colour, from straw to dark brown but fortunately its wing markings are constant. Principally, the oval (orbicular) and kidney shaped (reniform) pale marks halfway down the wing are clearly seen. On the trailing edge of each forewing there is a white 'W' mark and high up on each wing shoulder there is an elongated dark 'V'.

On some of the darker northern forms the marks may not be so obvious but they can usually be detected, knowing where to look.

It is quite a large moth with a forewing length of 25mm. The single generation flies June to August.

Young larvae feed on small flowers but later, feed on the roots and stems of grasses from the safety of a ground level chamber in which it hibernates. Pupation takes place below ground.

Dark-barred Twin-spot Carpet moth

Xanthorhoe ferrugata

The general similarity with the Red Twin-spot Carpet is easy to see - and at first I thought they were one and the same.

However, the main distinguishing features of the Dark-barred Twin-spot are
a) the rather more sombre colouring and
b) the distinct vee shaped notch on the forward edge of the dark band near the outer edge of the wing.

December moth

Poecilocampa populi

After several frosty nights, it was something of a surprise to find this moth on the wing but as its name suggests, it was flying true to form. It is common throughout much of Britain and Ireland and flies from October to December.

December moth antenna

The caterpillars are active from May to July before pupating in the soil. The widely varying pupation period of different moth and butterfly species helps to avoid species competition.

The caterpillars feed on a variety of deciduous trees, including Oak, Apple, Plum, Cherry and Hawthorn.

Dingy Footman moth

Eilema griseola and

The upper image shows the standard grey version of the Dingy Footman, the wings being, appropriately, a pale dingy grey (compared to the slate grey of the Common Footman) with a faint pale leading edge.

When variation in wing coloration or differing light conditions starts to cause confusion, the distinguishing feature that separates it from the Common Footman is the noticeably broader wing with a curved leading edge and a less well defined pale leading edge stripe.

The lower image is of a 10mm larval specimen found in late October. It was found on an external door at night and was probably looking for a suitable place to hibernate.

On emerging from hibernation, they will continue feeding through Spring and a mature larvae could reach a length of 25mm by May prior to entering pupation.

The apparently different wing shape is solely down to a slightly greater wing overlap in this image and is not a significant identification feature.

The larvae feed on lichens, algae, mosses and even withered leaves so food sources should not restrict its breeding limits and it is slowly extending its residential area northwards to the English Midlands.

Dun-bar moth

Cosmia trapezina

The Dun-bar moth is very variable in background coloration. The one seen here lies at the pale end of the range but they can extend through to dark brown with occasional grey and reddish forms. There is one form which has a dark brown band between the cross lines in the middle of the wings but generally the cross line markings are discrete and visible.

Dun-bar moth
Dun-bar moth

The single generation flies July to September. It over-winters as an egg and the larvae are found April to June.

The larvae have been found feeding on most broadleaved trees but will favour Pedunculate Oak, Elm, Birch, Blackthorn, Hawthorn and Willow. Large larvae are known to be omnivivorous and will eat other moth larvae.

Being a broadleaved tree feeder, it is most common in woodland habitats.

Early moth

Theria primaria

A moth that lives up to it's name is the Early Moth. In 2008 it was the first macro moth of the year to visit us. It is a single generation flier, the males being on the wing in January and February. The females have tiny little squared off wings and are incapable of flight. They just sit around on bare twigs and wait for the males to find them.

Date

Sighting

Early moth

The species is well distributed in the UK as far as southern Scotland. But, because of its early season, is not as well recorded as it might be.

The favoured larval foodplants are Blackthorn and Hawthorn and it is on these bare winter hedges that you will have the best chance of seeing the adults - if you are prepared to prowl the hedges by torchlight. The 15mm males can usually be found from 19.00 to 01.00hrs. But the 10mm females coyly wait until about 22.00hrs before making themselves 'available'.

Theria primaria
Theria primaria

The male moths tend to feign death when disturbed and in the lower image this enabled me to get a shot of the underside of a different specimen. The coloration is rather bland but it reveals that the hind wings, which are also pale on top, also carry central spots.

The larvae feed from April to May and then enter a long pupal state just below ground until the adults hatch in January and the females make the long climb up to an appropriate courting vantage point.

The male's forewings can be quite plain with just the two prominent dots and faint cross lines. In some areas of south-east England care is necessary in identifying late specimens because the Sloe Carpet moth which also favours Blackthorn, flies in March and April - and can look very similar although it tends to have rather more pointed wings and is rarer.

Selenia dentaria

This colourful moth characteristically holds its wings in the closed upright fashion of butterflies.

There are usually two generations a year. The upper image is of a first generation specimen found in early April, the markings being rather better defined and the coloration rather more contrasting.

Early Thorn moth
Early Thorn moth

Forewing length can range from 14mm to 23mm, depending on generation and gender, males of the 2nd generation tending to be the smaller and females of the 1st generation tending to be the larger. It is widely distributed across the UK, being found as far north as the Orkney Isles, in both rural and urban areas.

The larvae feed on Blackthorn, Hawthorn, Hazel, Birch, Sallows and Honeysuckle. Overwintering larvae will pupate in leaf litter beneath the food plant but the summer larvae pupate in cocoons spun between the growing leaves of the plant.

Early Thorn moth

25.07.2006

The lower image is of second generation individual found in July. The second generation is generally of a smaller size than the first and is of a lighter, softer coloration - although there can be quite a variation between individuals.

These images are of males. It is just about possible to see their strongly feathered antennae used to help locate the pheromones given off by the females. The females tend to be rather greyer in colour.

Deilephila elpenor

The Elephant Hawkmoth is very distinctive with its pink, orange and a hint of olive green forewings and starkly contrasting pink and black hindwings. Despite its common name, with a forewing length of 28mm to 33mm, it is not the largest of the UK Hawkmoths.

It is principally a single generation species flying from May to August but, occasionally, a few late summer fliers suggest that it may sometimes breed twice. It is often seen feeding on the wing, Hummingbird style, from flowers such as Honeysuckle and after dark is frequently attracted to light.

The larvae feed from June to September on a wide range of plants, Willowherbs, bedstraws, fuschias, Himalayan Balsam and others. When searching across bare ground for a suitable pupation site (in leaf litter or loose soil) the caterpillars frequently attract attention due to their large size and prominent 'eye' markings.

Fan-foot moth

Zanclognatha tarsipennalis

This is a small triangular shaped moth, its forewing only measuring about 15mm and at first glance it appeared to be a non-descript brown.

But, the straight line running across the trailing edge of the wings marked it out as something slightly different and closer inspection revealed the faint crescents and 'question mark' lines which identify the species.

Flame moth

Axylia putris

The Flame is recognised by the long dark streak down the leading edge of the forewing and the dark reniform mark halfway down the wing - which is all very well if you happen to see it with its wings 'splayed out' in normal moth fashion. However, when at rest it tends to draw its wings in tightly round its body, even more exaggeratedly than seen in the image. This gives it a pronounced 'broad at the shoulders, narrow at the rear' appearance. And is great camouflage if at rest on a twig or plant stem when it could easily be mistaken for a piece of straw.

Flame moth
Flame moth

The single generation flies from late May to July. Larvae feed at night from late July to October on Stinging Nettle, White Dead Nettle, Hedge Bedstraw and other common hedge growing plants and it will pupate through the winter, underground.

It is common throughout England, Wales and Ireland but tends to be localised in southern and south-western Scotland.

Flame Shoulder moth

Ochropleura plecta

This is a very common moth and, despite variations in colour intensity, it is easily recognised by the creamy white streak on the leading edge of the forewings. The orbicular and reniform stigma (the pale, oval and kidney shaped marks sometimes quite difficult to identify on other moths) stand out quite clearly.

Colour intensity is related to age. Newly emerged from pupation the wings are a dark walnut brown in sharp contrast with the pale leading edge stripe. With time the dark brown mellows and reveals subtle shades.

Pupation takes place in the soil. The 13mm pupa shown in the lower image was found in an open grassy hay meadow just below the surface in fine grained soil.

A slightly larger, slimmer and darker relative, Ochropleura leucogaster, whilst common in continental Europe, is a rare visitor to southern counties of the UK.

The caterpillars feed on a wide range of herbaceous plants including dock and plantain. And the larva in the adjacent image, found under a Hawthorn hedge when only 12mm long, after feeding quite happily on Ground Ivy and Dead Nettle, grew to 32mm within 12 days. Feeding takes place at night and the larvae rest at the base of the food plant during the day, characteristically in a head down position (the image having been rotated through 90 degrees).

The second image is of a one day old moth. Over time the colour then gradually fades and an old moth can look quite washed out but, still retains the characteristic pale leading edge to the wings.

The moths are to be found from April to September in Southern UK with numbers peaking in May/June and August due to two generations. Further north a single generation flies from late May to July.

Flounced Rustic moth

Luperina testacea

The Flounced Rustic is another species which can be quite variable in colour but consistent in its markings. The images show a mid-range form and a dark form. But pale straw - and intermediate versions, may also be found.

In coastal areas, further confusion can arise where the similar very variable Sandhill Rustic species is also to be found.

The larvae feed on the roots and stems of Common Couch, fescue grasses and sometimes cereals and spend much of their time underground where they will over-winter.

This subterranean existence results in a very pale almost colourless caterpillar. Pupation occurs in the leaf litter.

Four-dotted Footman moth

Cybosia mesomella

The placing of the tiny black dots on the wing is a constant and diagnostic feature - one near the leading edge and one near the trailing edge. Although, as the wings are invariably overlapped at rest, only three dots may be visible.

There is another form, f. flava, that has uniformly dull yellow wings - with the four dots. And there is a much larger yellow winged species, the Four-spotted Footman, Lithosa quadra, that has significantly larger spots.
