Platypria (Platypria) hystrix, is a species of leaf beetle found in India, China, Indonesia, Myanmar, Nepal, Sri Lanka, Thailand and Vietnam. [1]
Antenna thin, which is extending beyond scutellum over pronotum. There are five spines on each side of the anterior lateral lobe of elytra. [2] [3]
The adult female lays eggs singly on the adaxial side of the leaves. These individual eggs are inserted into a depression made on the leaf. Then the eggs are covered with a yellow secretion that gradually turns red-brown on drying. This secretion later forms the oblong-oval crusty ootheca with an average size of 1.03 to 1.32 mm in length. From the middle of the ootheca, a long, thread-like process can arise. Eggs are hatch in about 4 to 7 days after oviposition. Even after the hatching and formation of the leaf mine, this process and the ootheca outer wall are intact. [2] [4]
The first instar hatched out of the egg mines and starts to feed and move through the mesophyll tissues. The length of the first instar grub is about 1.8 mm. The larval head is chitinous brown and body translucent-greenish, where the alimentary canal is visible in dark green after feeding mesophyll tissues. The final instar is about 5 mm long. Pupation occurs in a separate U-shaped pupal mine. The pupal period is about 7 days. [2] [5]
It is found in wide varieties of host plants including: Cajanus cajan , Cajanus indicus , Desmodium gangeticum , Dolichos lablab , Erythrina arborescens , Erythrina stricta , Erythrina subumbrans , Erythrina variegata , Glycine max , Mucuna pruriens , Phaseolus , Pueraria montana var. lobata , Pueraria phaseoloides , Pueraria tuberosa , Sesbania aculeata , Sesbania grandiflora , Tephrosia candida , Castanea , Myrica rubra , Ziziphus , Rubus ellipticus , and Uncaria gambir . [2] [6] [7]
It has observed that Braconid wasps parasitize mature instars and ants attack pupa. [2]
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
Crocidolomia pavonana is a moth of the family Crambidae. Its caterpillar is a crop pest and is known as the croci or the cabbage cluster caterpillar. This moth is found in Africa and Asia, its range extending from South Africa through India to the Pacific Ocean, including Australia. The wingspan is about 25 mm (1 in). The larvae feed on Brassicaceae species and are considered an agricultural pest on cabbages. At first, they feed only on the undersides of the leaves. Later they feed on the rest of the leaves and the central shoot. The species was first described by Johan Christian Fabricius in 1794.
Acromis spinifex is a species of tortoise beetle from South America. The males have enlarged elytra which are probably used in male–male combat, while females are among the few tortoise beetles to show maternal care of their offspring.
Phratora vitellinae, the brassy leaf beetle, formerly Phyllodecta vitellinae, is a beetle of the family Chrysomelidae found in Europe and Asia. It feeds on Populus and Salix species. The evolution of its host plant preferences and the mechanism by which it uses host plant chemicals to make a larval defensive secretion have been the subject of intense study by research groups in Europe and the Nordic countries.
Brumoides suturalis, the three-striped lady-beetle, is a species of ladybird described by Johan Christian Fabricius in 1789. It is found in India, Pakistan, Bangladesh, Sri Lanka, Bhutan, Nepal, Indonesia, Philippines and Papua New Guinea. It was found on an indoor window ledge in Manchester, UK, on February 25, 2022. It likely hitchhiked on flowers.
Zygogramma exclamationis, commonly known as the sunflower beetle, is a species of leaf beetle belonging to the family Zygogramma. It is regarded as a pest of sunflower crops in North America.
Phratora laticollis is a species of leaf beetle found in Europe and Asia. This beetle is found on Populus species and the chemistry and production of its larval defensive secretions and host plant relationships have been studied extensively.
Harmonia octomaculata is a species of ladybird of the family Coccinellidae. It is found throughout India, Pakistan, Nepal, Bangladesh, Sri Lanka, Micronesia, and Australia.
Holotrichia serrata, commonly known as the sugarcane white grub, or cockchafer grub, is a species of dung beetle found in India, Bangladesh, and Sri Lanka.
Phratora tibialis is a species of leaf beetle found in Europe and parts of Asia. This beetle is found on willows and the chemistry and production of its larval defensive secretions and host plant relationships have been studied extensively.
Cassida circumdata is a species of tortoise beetle in the family Chrysomelidae. It is found in Indomalaya and the South Pacific islands.
Leptispa pygmaea, commonly known as rice leaf beetle, or rice blue beetle, is a species of leaf beetle native to India and Sri Lanka. It is a major pest of Asian rice.
Platypria (Platypria) erinaceus, is a species of leaf beetle native to India and Sri Lanka.
Platypria (Platypria) echidna, is a species of leaf beetle found India, Sri Lanka, Myanmar and Vietnam.
Aspidimorpha dorsata, commonly known as golden tortoise beetle or furcated tortoise beetle, is a species of leaf beetle widely distributed in Oriental region from Sri Lanka to South China towards Java, and Borneo.
Epistictina reicheana, is a species of leaf beetle found in India, Nepal, Sri Lanka and Tasmania.
Laccoptera (Laccopteroidea) quatuordecimnotata, is a species of leaf beetle native to India, and Sri Lanka.
