I Have A Question About Tolype Moths; They Have A Spot Of Curly, Wiry Hairs On Their Back. What Is It?

i have a question about tolype moths; they have a spot of curly, wiry hairs on their back. what is it? i tried to look it up and only found one person claiming females tore it off to protect eggs but they didnt sound confident. is it soft?

Hi! So sorry for the late reply.

The females do in fact use scales (hair) from their thoraxes to cover their eggs. However, I can’t find if they specifically use the dark hairs on their back. They may also use the white hair on their front or a mix of both, but I can’t find a source that specifies.

I also can’t find if the dark scales are soft, but I would avoid touching them as the caterpillars of the large tolype moth are covered poisonous spines. It is unclear if the adult moth has any toxins but it’s better to be safe than sorry!

Hope this helped! :]

The dew moth is a part of the family Erebidae. It was first described in 1758 by Carl Linnaeus. It is thought to have gotten its common name from how the moth hangs from a blade of grass or a leaf when resting during the day. This gives it a transparent look.

Description This species’s wings can vary in colour from cream to yellow. The forewing has 3 lines of black dots across it with the hindwing usually having only one black dot. The underside of the forewing is gray with a yellow margin. The body is black with yellow or black legs.

There are many found variations of this moth:

signata Borkh. - the middle rows of spots are connected by streaks

ab. fumosa Sandb. - has brownish ground colour; found in the north, but also found in Germany.

flavicans Bdv. - has brighter deep yellow wings and the apex of the abdomen is yellow; found in the Mediterranean and Anterior Asia.

nickerli Rebel - paler yellow, the forewing slightly dulled with the exception of the clearer yellow inner margin; found in the Alps and Northern Europe.

andereggi H.-Schiff. - has dark veins on the forewings, appearing like rays; found in the high Alps, and in the higher North.

riffelensis Fall. - considerably smaller, the ground colour is slightly dulled, the black vein-streaks are more numerous, especially the costa and median veins strongly sooty black; found in the high Alps, especially abundant above Zermatt.

lata Christ. - larger with broader wings and paler with very few markings, the hindwing often quite without markings; found in Russia over North Siberia to Kamtschatka.

insignata Stgr., - quite similar to the preceding, but with narrower wings. The forewing also with very few dots, and hindwing without any; found in East Siberia.

Wingspan Range: 27 – 33 mm (≈1.06 - 1.30 in)

Forewing Range: 11 – 18 mm (≈0.43 - 0.71 in)

Diet and Habitat The larva of this moth eat only lichen.

This moth is found in the Palearctic region. Its range starts from Ireland, then spreads south through Europe and east to northern and Central Asia. It can be found in countries such as Siberia, Kamchatka, Chukotka, and northern Mongolia. This species can even live in the limestone Alps up to 2,000 meters above sea level. However, it can not be found in the high north and parts of the Mediterranean region.

It prefers to live in mossy and lichen-covered rock corridors, on chalky and sandy areas and steep, rocky sparse grasslands, rocky coasts, shingle beaches, and calcareous grassland inland. It can also be found in bogs, forest meadows, and on heaths.

Mating Depending on location, this moth can be seen from May to July. It presumably mates during this time. Generations per year not listed.

Predators Not listed. However, the adult males fly in the afternoon, at dusk, after dark, and at dawn. The females are largely nocturnal. These moths are presumably preyed on by nighttime predators such as bats.

Fun Fact The dew moth has four subspecies:

Setina irrorella irrorella

Setina irrorella freyeri (Nickerl, 1845)

Setina irrorella insignata (Staudinger, 1881)

Setina irrorella mediterranea (Daniel, 1964)

Additionally, dew moth caterpillars do not cocoon in trees or foliage but rather in between stones or rocks.

Moth of the Week

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.

Moth of the Week

White-Lined Sphinx

Hyles lineata

The white-lined sphinx is a part of the family Sphingidae. They are sometimes known as the hummingbird moth because of their size and how they hover over flowers for nectar. The were first described in 1775 by Johan Christian Fabricius as Sphinx lineata.

Description The forewings are dark brown with tan stripe cutting across mirrors on both sides. The veins of the forewings are lined in white. The top edge of the forewing or the “costal margin” is outlined in a light brown and the forewing’s side edge or the “outer margin” is lined in gray. The hindwings are black with a pink stripe called the “median band.” The furry body is also dark and light brown with black, pink, and white stripes and spots.

Wingspan Range: ≈5.1 - 7.6 cm (2 -3 in)

Diet and Habitat Caterpillars of this species eat a variety of plants such as: Willow weed (Epilobium), Four o'clock (Mirabilis), Apple (Malus), Evening primrose (Oenothera), Elm (Ulmus), Grape (Vitis), and more. Caterpillars can form large groups when finding food and damage many gardens and crops.

Adult moths drink the nectar from various flowers such as: Columbines, Larkspurs, Four o'clock (Mirabilis), Petunia, Honeysuckle, Moonvine, and more. The type of flower an adult feeds from depends on the visibility during certain times of the day. At night they will feed from white flowers because they are easier to see in the dark. Durning the day, they will feed on brighter flowers.

This moth has a large range spanning from Southern Canada down to Central America, going through Mexico and most of the United States. They are found occasionally in the West Indies and on even rarer occasions in Eurasia and Africa. They live in habitats such as deserts, gardens, suburbs, and the Mountains of Colorado. However their population varies in many places.

Mating This moth has two generations per year with more in warmer climates. Eggs are laid in the spring on the host plants. A female can lay hundreds of eggs, which overwinter as larvae and emerge in February to November. This is also when they begin eating.

Predators This moth prefers to fly at night but can be seen during the day. It is preyed on by common enemies of moths: birds and bats.

Fun Fact Caterpillars were, and still are in some places, eaten by Native Americans. They were skewered, roasted, and dried to store/ground. When compared to hamburger meat, the larvae have almost as much fat but 1/3 less saturated fat and more energy in calories, protein, carbohydrate, riboflavin, and niacin.

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.
