Harrisina americana (Guérin-Méneville, 1844) | |
The grapeleaf skeletonizer (Harrisina americana) is a moth in the family Zygaenidae. It is widespread in the eastern half of the United States, [1] and commonly noticed defoliating grapes, especially of the Virginia creeper (Parthenocissus quinquefolia). The western grapeleaf skeletonizer ( Harrisina metallica ) is very similar to and slightly larger than H. americana, but their distributions are different.
Members of this family all produce HCN (hydrogen cyanide) a potent antipredator toxin. [2]
The adult has narrow black wings, usually held away from the body at rest, and a reddish collar. The wingspan is 18–28 mm, the length 8–12 mm. [3]
The larva has a dark head; the body is yellow with a complete black band across each abdominal segment. [3] The larvae can reach up to 15 mm in length. [4]
There are several generations per year in the south, and one in the north of its range. [4]
Eggs are lemon yellow, shaped like a capsule, slightly over 0.5 mm in length and are laid in clusters on the underside of leaves. [5] They hatch in about a week.
Larvae are stout, with ten bright yellow bands or lines of dots, and eleven black bands alternating. They have hair-like setae that, if brushed against, will give a rash that lasts several days. They feed in groups that become progressively smaller as the larvae age. They constantly live on the underside of the leaves, and frequently line up side by side. Development from hatch to pupation takes about 40 days. [4]
This is the only moth species that feeds gregariously on grape foliage. [5]
The pupa is brown, and lasts about two weeks in the summer, when multiple generations are possible. The pupa is also the overwintering stage, among leaves at the base of the food plant.
Adult moths are uniformly black except for a reddish or orange collar. The body and wings are long and narrow, and the abdomen is usually held curled upwards, with a tuft of hairs at the tip. Adults are active visiting flowers during the day as well as at night. They live only a few days. [5]
The Zygaenidae moths are a family of Lepidoptera. The majority of zygaenids are tropical, but they are nevertheless quite well represented in temperate regions. Some of the 1000 or so species are commonly known as burnet or forester moths, often qualified by the number of spots, although other families also have 'foresters'. They are also sometimes called smoky moths.
The Scotch argus is a butterfly of the family Nymphalidae. In spite of its English name argus, it is not a close relation of the brown argus nor the northern brown argus.
The geranium bronze or brun des pélargoniums in French, is a butterfly in the family Lycaenidae.
Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths. It was first described by Johan Christian Fabricius in 1793. The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.
Catopsilia pomona, the common emigrant or lemon emigrant, is a medium-sized pierid butterfly found in Asia, Cambodia and parts of Australia. The species gets its name from its habit of migration. Some early authors considered them as two distinct species Catopsilia crocale and Catopsilia pomona.
Daphnis nerii, the oleander hawk-moth or army green moth, is a moth of the family Sphingidae. It was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Sphecodina abbottii, or Abbott's sphinx, is a moth of the family Sphingidae. The species was first described by William John Swainson in 1821.
The Limacodidae or Eucleidae are a family of moths in the superfamily Zygaenoidea or the Cossoidea; the placement is in dispute. They are often called slug moths because their caterpillars bear a distinct resemblance to slugs. They are also called cup moths because of the shape of their cocoons.
Citheronia azteca is a moth of the family Saturniidae that lives in Guatemala, Belize and Mexico.
Drymonia dodonaea, the marbled brown, is a moth of the family Notodontidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in Europe and in the area surrounding the Caucasus.
Ancyloxypha numitor, the least skipper, is a North American butterfly in the family Hesperiidae. They have a weak, Satyrinae-like flight.
Ctenucha virginica, the Virginia ctenucha, is a moth of the family Erebidae. The species was first described by Eugenius Johann Christoph Esper in 1794.
Harrisina metallica, the western grapeleaf skeletonizer, is a species of moth of the family Zygaenidae. It is found in the Southwestern United States, from California to Texas, north to Colorado and Utah and in northern Mexico.
Chrysoesthia sexguttella, common name the orache leafminer moth, is a moth in the family Gelechiidae. It is found in all of Europe, east to southern Siberia, as well as the north-eastern parts of North America, where it might be an introduced species.
Pollanisus viridipulverulenta, the satin-green forester, is a moth of the family Zygaenidae. It is found in the eastern part of Australia.
Vitacea polistiformis, the grape root borer, is a moth of the family Sesiidae. It is found throughout the midwest of the United States, south to Florida and Texas. It is the most serious threat to grapes in Florida.
Zygaena sarpedon is a moth of the Zygaenidae family. It is found in France, Italy and on the Iberian Peninsula.
Zygaena anthyllidis is a species of moth in the Zygaenidae family. It is found in France and Spain.
Acoloithus falsarius, or Clemens' false skeletonizer, is a moth species in the zygaenid subfamily Procridinae. The species occurs in North America and was described by James Brackenridge Clemens in 1860. A. falsarius has Hodges number 4629 and is the type species of genus Acoloithus.
Proteodes carnifex is a species of moth in the family Depressariidae. It is endemic to New Zealand. Both the larvae and the adults of this species are variable in appearance. However the adults are normally easily identified as the outline is characteristic and the size is consistent. In appearance, adult moths mimic the leaves of their larval host plants. This species has been found near Wellington in the North Island, the tableland of Mount Arthur, in the Canterbury region, Arthur's Pass and at Lake Wakatipu in the South Island. The larval hosts of this species are southern beech trees, particularly black beech and mountain beech but larvae have also been found on Nothofagus fusca, Nothofagus truncata and Nothofagus menziesii. The female moth deposits her eggs individually on the underside of native beech tree leaves. Once hatched the larvae feed on those leaves through winter and spring and then pupate in January. The adult moth emerges from the pupa after fourteen days and is on the wing from January until April. They are day flying moths and are not attracted to light. Various insects parasitise the larvae of this moth including several species of wasp as well as flies including the endemic fly, Pales funesta.
