Opisina arenosella Walker, 1864 | |
Opisina is a monotypic moth genus in the family Xyloryctidae described by Francis Walker in 1864. Its only species, Opisina arenosella, the coconut black-headed caterpillar, was described by the same author in the same year. [1] It is found in India, Sri Lanka, Bangladesh and Myanmar. [2]
The wingspan is 10–15 mm (0.39–0.59 in). Adults are grey.
The larvae are gregarious and are serious pests of coconut trees. They defoliate their host plant. [3]
Lepidoptera or lepidopterans is an order of winged insects that includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order with 126 families and 46 superfamilies, and one of the most widespread and widely recognizable insect orders in the world.
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek geo γεω, and metron μέτρον "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. Geometridae is a very large family, containing around 23,000 described species; over 1400 species from six subfamilies are indigenous to North America alone. A well-known member is the peppered moth, Biston betularia, which has been the subject of numerous studies in population genetics. Several other geometer moths are notorious pests.
Graphium doson, the common jay, is a black, tropical papilionid (swallowtail) butterfly with pale blue semi-transparent central wing bands that are formed by large spots. There is a marginal series of smaller spots. The underside of wings is brown with markings similar to upperside but whitish in colour. The sexes look alike. The species was first described by father and son entomologists Cajetan and Rudolf Felder.
The African armyworm, also called okalombo, kommandowurm, or nutgrass armyworm, is a species of moth of the family Noctuidae. The larvae often exhibit marching behavior when traveling to feeding sites, leading to the common name "armyworm". The caterpillars exhibit density-dependent polyphenism where larvae raised in isolation are green, while those raised in groups are black. These phases are termed solitaria and gregaria, respectively. Gregaria caterpillars are considered very deleterious pests, capable of destroying entire crops in a matter of weeks. The larvae feed on all types of grasses, early stages of cereal crops, sugarcane, and occasionally on coconut. The solitaria caterpillars are less active and undergo much slower development. The species is commonly found in Africa, but can also be seen in Yemen, some Pacific islands, and parts of Australia. African armyworm outbreaks tend to be devastating for farmland and pasture in these areas, with the highest-density outbreaks occurring during the rainy season after periods of prolonged drought. During the long dry seasons ("off-season"), the population densities are very low and no outbreaks are seen.
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
The brown-dotted clothes moth is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the nominate subfamily Tineinae. It is the type species of its genus Niditinea.
Carmara is a monotypic moth genus of the family Noctuidae. Its only species, Carmara subcervina, is found in Sri Lanka, Japan, Taiwan, Borneo and Australia. Both the genus and species were first described by Francis Walker in 1864.
Parasa lepida, the nettle caterpillar or blue-striped nettle grub, is a moth of the family Limacodidae that was described by Pieter Cramer in 1799. It is a native minor pest found in the Indo-Malayan region, including India, Sri Lanka, Vietnam, Malaysia and Indonesia. It is an introduced pest to urban trees in western Japan.
The Depressariinae – sometimes spelled "Depressiinae" in error – are a subfamily of moths in the superfamily Gelechioidea. Like their relatives therein, their exact relationships are not yet very well resolved. It has been considered part of family Elachistidae sensu lato or included in an expanded Oecophoridae. In modern classifications they are treated as the distinct gelechioid family Depressariidae.
Batrachedra arenosella, the armoured scale eating caterpillar or the coconut moth, is a species of moth of the family Batrachedridae. It was first described by Francis Walker using specimens collected in Auckland, New Zealand. It has been hypothesised that the New Zealand moth may contain two distinct species. As well as the moth species in New Zealand, this name has been applied, perhaps incorrectly, to moths found in India, Indonesia, the Malay Peninsula, and Réunion, as well as in Australia, from the Northern Territory and northern Queensland to New South Wales and South Australia.
Anatrachyntis incertulella, the pandanus flower moth, is a small cosmet moth species. It belongs to subfamily Cosmopteriginae. This was the first "micromoth" species to be described from Hawaiʻi. The type specimens were collected there by the 1820s Beechey expedition and described by the English entomologist Francis Walker in 1864; they are now in the British Museum of Natural History.
The Chrysauginae are a subfamily of snout moths. They are primarily Neotropical and include about 400 described species.
Tirathaba rufivena, the coconut spike moth, greater coconut spike moth or oil palm bunch moth, is a moth of the family Pyralidae. It is found from south-east Asia to the Pacific islands, including Malaysia, the Cook Islands, the Philippines and the tropical region of Queensland, Australia. They are considered as a minor pest.
Xyloryctidae is a family of moths contained within the superfamily Gelechioidea described by Edward Meyrick in 1890. Most genera are found in the Indo-Australian region. While many of these moths are tiny, some members of the family grow to a wingspan of up to 66 mm, making them giants among the micromoths.
The Coconut black headed caterpillar, is a species of moth found in throughout East Asian countries including Bangladesh, India, Sri Lanka, Myanmar, as well as Indonesia. It is considered a pest of coconut palm trees, causing considerable damage to the trees, and reducing the plant's yield significantly and can be a major problem where coconuts contribute to the economy. The species exists on coconut palms through its life stages from larval to moth, and utilizes the tree fronds as a main source of nutrition. Various methods of control have been explored, yet the primary control method is the administration of pesticides directly to the root of the coconut palms.
Euproctis semisignata is a moth of the family Erebidae first described by Francis Walker in 1865. It is found in India and Sri Lanka.
Avitta quadrilinea is a moth of the family Noctuidae first described by Francis Walker in 1863. It is found in Borneo, Peninsular Malaysia, Thailand, the Indian subregion, the Philippines, Sulawesi and Sri Lanka.
Cophanta funestalis is a moth of the family Noctuidae first described by Francis Walker in 1864. It is found in Indo-Australian tropics of India, Sri Lanka, Thailand, Borneo, New Guinea and Australia.
Erupinae is a subfamily of the lepidopteran family Crambidae. It was described by Eugene G. Munroe in 1995.
