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.

Moth of the Week

African Death’s-Head Hawkmoth

Acherontia atropos

The African death's-head hawkmoth is part of the family Sphingidae and is the most widely recognized of the three species of Death’s-Head Hawkmoth. The species was described in 1758 by Carl Linnaeus. Its common name comes from the skull shape on the back of its thorax. It’s binomial name comes from the river Acheron in Greece, which was believed to lead to the Underworld, and the Greek goddess Atropos respectively.

Description The forewings are black/brown with mottled shades of brown while the hindwings are buff orange with two black/brown stripes that curve with the edge of the hindwing. The head and thorax are the same black/brown color as the forewings interrupted by the brown skull on the back of the thorax. The abdomen is the same buff color as the hindwings with similar stripes of the same color. There is also a single stripe down the center of the abdomen called the “dorsal stripe.”

Average Wingspan: 13 cm (5 in)

Females are large than males with a rounded abdomen tip and larger, thicker antennae

Males have a pointed abdomen tip

Diet and Habitat Larva of this species mainly eat the leaves of potato plants which have alkaloids. The larva accumulate these toxins to become unpalatable to predators. Adults eat the nectar of flowers and stolen honey from the beehives of the Western Honey Bee. They are able to mimic the scent of bees and steal the honey undetected. They use their proboscis, a tube used to drink nectar and honey, to break the honey comb.

Their ranges stretches from the Middle East, as far south as the southern tip of Africa, as far north as southern Great Britain, as far east as India and western Saudi Arabia, and as far west as the Canary Islands and Azores. It is known to move into western Eurasia, but a majority do not survive the winter.

Mating This moth has multiple generations per year. In Africa, the broods are continuous. In the northern range, the larva overwinter in the pupal stage. Eggs are laid singly on the underside of species in mainly Solanaceae but also Physalis, Verbenaceae, Cannabaceae, Oleaceae, Pedaliaceae and others.

Predators This moth can emit a special squeak noise by sucking in air to vibrate a flap in its mouth and throat. The purpose of this squeak is unclear, but the two hypotheses are it is to scare away predators or to mimic the sound of a queen bee makes for the workers to stop moving to easier raid beehives for honey. They are also immune to bee venom and can mimic the scent of bees.

Fun Fact This moth has appeared many times in pop culture as symbols of death and evil:

It appeared in The Hireling Shepherd, Bram Stoker's Dracula, Un Chien Andalou, the promotional marquee posters for The Silence of the Lambs, in the music video to Massive Attack's single, "Butterfly Caught,” and on the American edition's cover of José Saramago's novel Death with Interruptions.

It is mentioned in Susan Hill's Gothic horror novel I'm the King of the Castle and John Keats’s "Ode to Melancholy.”

It is referred to in The Mothman Prophecies.

Finally, the moth is used as a calling card by the serial killer Buffalo Bill. However, in the movie script they are referred to under a different species of death’s-head hawkmoths.

Moth of the Week

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.

Moth of the Week

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.
