Rosy Maple Moth Pls

rosy maple moth pls

Hello! I have covered this moth before, you can find it here! :]

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! :]

Salt Marsh Moth

Estigmene acrea

The salt marsh moth is a part of the family Erebidae. This species was first described in 1773 by Dru Drury. It is also known as the acrea moth.

Description Both male and female moths have white heads, thoraxes, and forewings with a varying pattern of black spots on the forewings, with some moths having no pattern at all. They also share an orange-yellow abdomen with a vertical line of back dots. On the male, the hindwings are the same organge yellow while on females the hindwings are white. Both males and females have three or four black dots on each hindwing.

Wingspan Range: 4.5 - 6.8 cm (≈1.77 - 2.68 in)

Diet and Habitat The caterpillar was first thought to be a pest to salt-grass, but in fact it prefers weeds, vegetables, and field crops such as dandelions, cabbage, cotton, walnuts, apple, tobacco, pea, potato, clovers, and maize. Adults do not feed.

This moth is found in North America, the Democratic Republic of the Congo, Kenya, Colombia, and Mexico. It prefers open habitats such as openings in woods, thickets, farm fields, grasslands, and marshes. It is called the “salt marsh moth” because it is common in coastal salt marshes (tidal marshes) along Pacific, Atlantic, and Gulf coasts.

Mating This species of moth does not emit pheromones from the tip of its abdomen but instead from its throat or the to of its abdomen. These moths are seen from May to August but can be seen all year in southern Florida and Texas. It is presumably during May and August they mate in most parts of their range while they mate all year round in Florida and Texas.

Yellowish eggs are laid in clusters on the host plant leaves. Females usually produce 400 to 1000 eggs in one or more clusters. It is possible to find a single egg cluster containing 1200 eggs. Eggs hatch in four to five days.

Predators This species is frequently parasitized as larvae, usually by flies in the Tachinidae family. In Arizona, the most common parasites were Exorista mellea and Leschenaultia adusta while two other parasitic flies were also seen: Gymnocarcelia ricinorum and Lespesia archippivora.

Both the larval and egg stages are oararzitized by Hymenopteran parasitoids such as Apanteles diacrisiae; Therion fuscipenne, T. morio, Casinaria genuina, Hyposoter rivalis; Psychophagus omnivorus, Tritneptis hemerocampae Vierick; Anastatus reduvii; and Trichogramma semifumatum.

A cytoplasmic polyhedrosis virus is known to harm this species but there are little data on its importance and effect.

General predators such as lady beetles, softwinged flower beetles, and assassin bugs prey on these caterpillars, but are not thought to have a large impact on population.

Fun Fact This species has 4 subspecies: Estigmene acrea acrea, Estigmene acrea arizonensis (Rothschild, (1910)) (Arizona), Estigmene acrea mexicana (Walker, (1865)) (Mexico), Estigmene acrea columbiana (Rothschild, (1910)) (Colombia).

I have a poplar hawk moth and a elephant hawk moth for you!

Hello! So sorry for the late reply, these are such great photos!

Fun fact: the poplar hawk moth is known for how it pushes its hindwing up so that the hindwing is seen in front of the forewing. This hides the red patch on the hindwing which this species will display if disturbed. (Source)

Another fun fact: elephant hawk moths have very sensitive eyes that allow them to have colour vision even at nighttime. (Source)

I’m sure you probably know a lot about these species if they are in your area, but let me know if you’d like to see a post on these moths! :]

Macrocilix maia Moth

Macrocilix maia

The Macrocilix maia moth is a part of the family Drepanidae. It was first described in 1888 by John Henry Leech as a part of the genus Argyri. It has no recognized common name and is mainly called by its scientific name.

Description

The forewings and hindwings are a matching cream color and slightly translucent. The main attraction of the wings are two mirror images of a fly, one on each forewing. The body of the “fly” is black with red eyes/head and a white accent in the middle of its abdomen. They are outlined in amber and black with amber specks on the outer edge of the forewing called the outer margin. The hindwings have an amber splotch on the innermost edge, called the inner margin, that transitions to black and white as it reaches the corner. This is meant to look like a bird dropping that the flies are eating.

The body is a matching amber/dark brown as the bird dropping to blend in. The antennae are cream.

Wingspan Range: 3.7 - 4.5 cm (≈1.46 - 1.77 in)

Diet and Habitat This moth mainly, feeds on the Chinese Cork Oak as larva and do not feed as adults.

They are found around Asia in Borneo, China, India, Japan, Korea, Peninsular Malaysia, Sumatra, and Taiwan. This moth prefers habitats like forests and jungles.

Mating The eggs are laid close to the host plant and adults are emerge in May. Mating season is presumably around this time.

Predators This moth is most recognizable by its use of mimicry. It’s wings resemble flies eating bird droppings to make it appear unappealing to predators. It also gives off a bad smell to further sell the act.

Fun Fact The type of camouflage this moths uses is called Batesian mimicry. Named after Henry Walter Bates, Batesian mimicry is when a palatable animal, or one without toxins or poison, evolves to look like an unpalatable/undesirable animal to protect itself from predators.

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.
