Chimney Sweeper

Odezia atrata

The chimney sweeper is a part of the family Geometridae. It belongs to a monotypic genus, meaning it’s the only moth species in the genus Odezia, which was created in 1840 by Jean Baptiste Boisduval. It was first described in 1758 by Carl Linnaeus.

Description This moth is mostly black with white on the tips of the forewing (called the “apex”) and on the fringe of the forewing.

There have been a few variations in color:

- Odezia atrata pyrenaica, which is found in Pyrenees and central Italy, the wings are “dusted” in a brownish yellow with a stronger color on the forewing.

- Ab. Odezia atrata nigerrima, described by Paul Thierry-Mieg, was a female with no white apex or fringe.

- This moth’s wings may become brown from wear over time.

Wingspan Range: 23–27 mm (≈0.91 - 1.06 in)

Forewing Range: 12–15 mm (≈0.47 - 0.59 in)

Diet and Habitat The caterpillars of this species mainly eats the flowers and seeds of pignut (Conopodium majus).

This moth is distributed in the Palearctic region. In the west, it’s range reaches the Iberian Peninsula through western and central Europe and the British Isles. In the east, they can be found in Sakhalin and the Amur-Ussuri region. I’m the north, this moth reaches central Fennoscandia. Finally, in the south they are found in Italy to the Balkans.

These moths were once very common in Austria, but now the species is a rare occurrence.

They inhabit ditch edges, meadows, bogs, moors, lake sides, chalk downland, limestone grassland, woodland edges and hedgerows in southern Britain

Mating In Belgium and the Netherlands this moth can be seen flying from June to August. It presumably Nate’s during this timeframe.

Predators This moth flies during the day, especially in sunshine. They are presumably preyed on by birds and other daytime predators.

Fun Fact The chimney sweeper can be confused for the Small Blue butterfly (Cupido minimus), which also lives in the Palearctic region, as its wings may become brown from wear.

Kentish Glory

Endromis versicolora

The Kentish glory was first described in 1758 by Carl Linnaeus. It is a part of the family Endromidae which was created in 1810 by Ferdinand Ochsenheimer. This is a monotypic genus, meaning there is only one species in it being the Kentish glory.

Description The male and female of this species are clearly told apart by their colors and size.

Males are darker and more orange than females with feathery antennae

Males hindwings are orange

Females are paler/more washed out in color and larger to carry eggs

The forewings of this moth are a marbled black, orange, and white. The outer edge of the wing called the outer margin is brown with white stripes along the veins. The females hindwings are the same marbled black, brown, and white with a brown edge. The males hindwings are orange with brown markings.

The legs and antennae are black while the thorax is brown and white. The females abdomen is black while the males abdomen is a similar orange to the hindwing.

Sources differ on wingspan range.

Wikipedia: 50 - 70 mm (≈1.97 - 2.76 in)

Butterfly Conservation: Male 27 - 30 mm (≈1.06 - 1.18 in), Female 34 - 39 mm (≈1.34 - 1.54 in)

Diet and Habitat The larvae of this species eats mainly birch (Betula species) but will eat other trees and shrubs such as Alnus, Corylus, Tilia and Carpinus species. Adults do not feed.

This moth’s range used to be much larger, such as living in the southern and western English counties of Kent, Sussex, Berkshire, East Anglia, Herefordshire, and Worcestershire and the southeastern Welsh county of Monmouthsire.

Now this moth is restricted to living in the central and eastern Highlands of Scotland. It is seen in the Scottish counties of Perthshire, Inverness-shire, Morayshire, Aberdeenshire and Kincardineshire.

They prefer to inhabit open birch woodland and lightly wooded moorland.

Mating Females use pheromones to attract males, who can detect them from 1-2 km (≈0.62 - 1.24 mi) away.

This species has one single generation per year. The females lay their eggs, which are yellow at first then purplish-brown, in batches of 10-20 eggs on low birch scrub at an average height of 1.2m (≈1.31 yd). They prefer to let them on sheltered, unshaded saplings, usually the first few batches are near where the females emerged. The eggs hatch after 10 to 14 days.

Predators Males usually fly during the day from mid morning to early afternoon while females fly at dusk. Because of this males are presumably preyed on by daytime birds while females are preyed on by bats.

Fun Fact The females do not fly as strong as males due to the eggs they carry as it weighs them down. Females tend to lay their first few batches of eggs close to where they emerged due to this fact.

African Wild Silk Moth

Gonometa postica

The African wild silk moth is a part of the family Lasiocampidae. It was first described in 1855 by Francis Walker. It is also known as the Brandwurm in its larval stage in Afrikaans, Kweena in its pupal stage in Tshwana, and Molopo moth/mot in English and Afrikaans.

Description The female of this moth is much longer and larger than the male due to having to carry eggs. The male is about half the size of the female and much thinner.

The female has a light brown abdomen with a dark brown thorax and head. The female’s forewings are striped light brown, dark brown, and gray. The hindwings are a yellow-brown with a dark brown edge.

The male has a dark body and wings with a transparent portion of the hindwing.

Female Forewing Range: 35–42 mm (

Male Forewing Range: 21–25 mm (

Diet and Habitat Larva of this species eat Acacia erioloba, A. tortilis, A. melifera, Burkea africana, Brachystegia spp., and Prosopis glandulosa. The larva will feed from the same tree it’s entire life unless there are two many other caterpillars. When there is a large number of caterpillars, they may defoliate the whole tree and the larva must move in order to not starve.

This moth mainly inhabits savannas with many Acacia trees, especially in drier areas. These moths contribute to the Acacia environment by providing food to predators and nutrients to plants through feces. Cocoons are usually found on Acacia tees.

Mating Males detect females’ mating pheromones with their antennae. Males fly to the females because the females are weighed down by the eggs. The female contains about 200 eggs which are laid on the food plant after fertilization. Eggs hatch in about two weeks. Eggs are laid in clumps and the newly hatched caterpillars grow as a group and become more solitary with time.

Predators This moth is preyed on by parasitic wasps and flies. These insects lay their eggs on the caterpillar and feed off of its resources until the moth larva cocoons. The parasites live off the cocoon and grow to adulthood while killing the pupa. Specifically, these larva are subject to parasitism by Diptera and Hymenoptera, the most common parasitoids being Palexorista species from the Tachinidae and Goryphus species from the Ichneumonidae.[6]

To combat external predators and weather, the caterpillars build a tough cocoon. Caterpillars and their cocoons are also covered in stinging hairs to deter predators from touching them. Female cocoons are larger than male cocoons.

Fun Fact In Madagascar, wild silk has been harvested for centuries, and this knowledge has been introduced to southern Africa. The cocoons are harvested commercially in Namibia, Botswana, Kenya and South Africa, and the species also occurs in Zimbabwe and Mozambique. They are difficult to harvest due to the cocoons being covered in calcium oxalate. Oxford University discovered and patented a method known as demineralizing using a warm solution of EDTA (ethylenediaminetetraacetic acid) that soften the cocoons by dissolving the sericin. This lets the silk unravel without weakening it.

- Wild African silk moth cocoons are also used as ankle rattles in southern Africa by San and Bantu tribes. They are filled with materials such as fine gravel, seeds, glass beads, broken sea shells, or pieces of ostrich eggshell.

- Furthermore, the cocoons have long been known to cause the death of cattle, antelope and other ruminants in the Kalahari. During drought periods, the cocoons are eaten, probably because they resemble acacia pods. The silk is indigestible and blocks the rumen of multiple-stomach animals, causing starvation.

- Finally, the protein found in this species’s slik contains many basic amino acids making it a potentially useful biomaterial in cell and tissue culture.

Crimson-Speckled Moth

Utetheisa pulchella

The crimson-speckled moth is a part of the family Erebidae. This species was first described in 1758 by Carl Linnaeus. It is also called the crimson-speckled flunkey and crimson-speckled footman.

Description The forewings are white or cream with red spots broken up by smaller black spots. Black dots also line the lower edge of the forewing called the outer margin. The pattern of spots may vary and the red splotches can merge into lines across the wings. The hindwings are much blander, they are all white except for a waved black/dark brown edge on the bottom of the hindwing, also called the outer margin, and a mark of the same color in the middle of the hindwing.

The head and back of the thorax is spotted buff yellow and black while the abdomen is only white or cream to match the wings. The moth’s legs are white and its antennae are dark brown/black and filiform.

These colors warn predators that this species is toxic.

Wingspan Range: 29 – 42 mm (≈1.14 - 1.7 in)

Diet and Habitat The caterpillars eat forget-me-nots, starflower, ribwort plantain, and plants from the genuses Echium, Solanum, and Anchusa. In their Afrotropical range they feed on Northern bluebell and plants in the genuses Lithospermum, Heliotropium, Trichodesma and Gossypium.

These plants contain alkaloids which makes the caterpillars and adult moths toxic to predators.

This species has a large range and are native to the Afrotropics, North Africa, the Near East, and Central Asia. This species also migrates to the United Kingdom, though its patterns are defined as “sporadic.”

These moths inhabit dry open places, meadows, shrublands, grasslands, and parks.

Mating This species has multiple generations a year: the broods are “continuous” in the tropics while elsewhere they have 3 per year.

Predators These moths fly both during the day and night. They have no camouflage but instead their colors advertise to predators that they are unpalatable. The plants they eat as caterpillars contain alkaloids which make them toxic to birds and other animals.

Fun Fact The crimson-speckled moth has 5 subspecies: Utetheisa pulchella antennata, Utetheisa pulchella completa, Utetheisa pulchella dilutior, Utetheisa pulchella kallima, and Utetheisa pulchella pulchella.

Angle Shades

Phlogophora meticulosa

Image source

The angle shades is a part of the family Noctuidae. This species was first described in 1758 by Carl Linnaeus. According to Wikipedia, this moth gets its common name from the colors and marking on its wings.

Description The forewings of this moth are shaped with a sharp point. Most of the forewing is buffish as well as the head, legs, body, and antennae. The middle of the forewing is split by a triangle. The bottom of the triangle lays on the termen of the forewing or “the edge of the wing most distant from the body.” The triangle is made of layers of brown and pink. The hindwings are whitish with darker veins.

ab. roseobrunnea ab. nov [Warren], the central triangle is a rich red brown tinged with fulvous (tawny/orange), the whole wing reddish tinged, and the green shades all strongly mixed with red, the metathorax and dorsal tufts also being deep fulvous instead of green; found in São Jorge Island in the Azores

Wingspan Range: 45 - 52 mm (≈1.77 - 2.05 in)

Diet and Habitat This species eats a wide range of herbaceous plants such as Common Nettle (Urtica dioica), Hop (Humulus lupulus), Red Valerian (Centranthus ruber), Broad-leaved Dock (Rumex obtusifolius), Bramble (Rubus fruiticosus), Hazel (Corylus avellana), birches, oak, basil, and broccoli.

They are distributed throughout Europe. Their reach spans eastto the Urals, southeast to Syria, Armenia, and Asia Minor, west to Azores, and south to Algeria. They are a strongly migratory species. It is found in a variety of habitats such as gardens, hedgerows, fens, woodland, grasslands, farmland, wetlands, heathland, and moorland.

Mating This moth is generally seen from May to October and has two generations per year. The larva overwinter in soil as pupa.

Predators This species flies mainly at night. They are presumably preyed on by nighttime predators such as bats. This moth uses its coloration to disguise itself as a wilted leaf when at rest. They can be seen during the day resting on walls, vegetation, and feces.

Fun Fact The angle shades is attracted to light and sugar.

Moth of the Week

Drinker

Euthrix potatoria

The drinker moth is of the family Lasiocampidae. It was described and named in 1758 by Carl Linneaus. Linneaus chose the species name potatoria as it means ‘drinker-like.’ Dutch entomologist Johannes Goedaert had previously called the moth dronckaerdt, meaning ‘drunkard,’ “because it is very much inclined to drinking” or because this moth repeatedly puts its head into water. The common name ‘drinker’ comes from the same reason.

Description This moth is distinguishable from other eggar moths by a diagonal line crossing the forewing and two white spots also on the forewing. Males are usually reddish or orangish-brown with yellow patches. Males in East Anglia are often yellowish. Females can be yellow, a pale buff, whitish, or a darker reddish-brown than the males. Male and females also differ in size and antennae shape: females are slight larger than males, and males have fluffier antennae.

Wingspan Range of Fully Grown Drinker: 45–65 mm (≈1.77 - 2.56 in)

Diet and Habitat The caterpillars of this species feed on grasses and reeds in genuses such as Alopecurus, Deschampsia, Dactylis, Elytrigia, Carex, Luzula, and other Gramineae. A few examples are Cat grass (Dactylis glomeratus), Common Reed (Phragmites australis), Reed Canary-grass (Phalaris arundinacea), and Wood Small-reed (Calamagrostis epigejos).

In the spring, they feed mainly at night and can be found resting on low vegetation during the day. The larva also supposedly drink morning dew because it had been observed to repeatedly put its head in water.

This moth can be found in Europe. It is common throughout England and Ireland but tends to favor western Scotland over eastern Scotland. It prefers habitats of marshy places such as fens, riversides, tall and damp grassland, marshes, damp open woodland, scrub, and ditches. However this species does sometimes live in drier habitats such as grassy terrain and urban gardens.

Mating Adults can been seen between July and August and presumably mate during this time. There is only one generation per year. Eggs are laid mainly on the stems of grasses or reeds in small clusters.

Predators Adult moths fly at night and are presumably preyed on by nocturnal predators such as bats.

Fun Fact Both sexes of the drinker moth are attracted to light, but males are especially susceptible.
