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.
The Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
Charidotella sexpunctata, the golden tortoise beetle, is a species of beetle in the leaf beetle family, Chrysomelidae. It is native to the Americas, and very broadly distributed. Charidotella sexpunctata was formerly known as Metriona bicolor. The species has also been seen in regions reaching up to Argentina.
Cassida is a large Old World genus of tortoise beetles in the subfamily Cassidinae. The natural history of Cassida sphaerula in South Africa is a typical life cycle. Several species of Cassida are important agricultural pests, in particular C. vittata and C. nebulosa on sugar beet and spinach. The thistle tortoise beetle has been used as a biological control agent against Canada thistle.
The thistle tortoise beetle is a species of beetle in the subfamily Cassidinae and the genus Cassida. The thistle tortoise beetle can be recognized by its green, rounded back and it can be found on thistle plants in many regions of North America and Europe. The thistle tortioise beetle was first discovered in 1902 in Lévis, Quebec. In 1931, Nellie F. Paterson was the first to document the mature larva. Later, the instar larva of this species was first recorded in 2004 by Jolanta Świętojańska. The thistle tortoise beetle exhibits multiple defense behaviors, such as a flexible shield, providing a barrier against the mandibles of predators, and an excretion that protects the eggs as well.
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.
Aspidimorpha is a large Old World genus of beetles belonging to the family Chrysomelidae and tribe Aspidimorphini. The genus name is frequently misspelled as "Aspidomorpha", due to an unjustified spelling change in 1848.
Trachymela sloanei, known generally as the Australian tortoise beetle or small eucalyptus tortoise beetle, is a species of leaf beetle in the family Chrysomelidae.
Cassida circumdata is a species of tortoise beetle in the family Chrysomelidae. It is found in Indomalaya and the South Pacific islands.
Aspidimorpha dorsata, is a species of leaf beetle widely distributed in South Asia and South East Asia.
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.
Aspidimorpha lobata, is a species of leaf beetle found in India, Sri Lanka and Bangladesh.
Cassida (Crepidaspis) cognobilis, is a species of leaf beetle found in India, Sri Lanka, Laos and Thailand.
Chiridopsis bipunctata, commonly known as Indian green tortoise beetle or sweetpotato tortoise beetle, is a species of leaf beetle found in India, Thailand and Sri Lanka. They are often seen on plants in the family Convolvulaceae.
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.
Notosacantha vicaria is a species of leaf beetle native to India, and Sri Lanka.
Silana farinosa, commonly known as curry-leaf tortoise beetle, is a species of leaf beetle native to Indo-China, India, Sri Lanka, Thailand and introduced to Peninsular Malaysia.
Epistictina is a genus of tortoise beetle found in Asia. There are about 5 species in the genus.
