Coccinella transversalis, commonly known as the transverse ladybird [1] or transverse lady beetle, [2] is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. [1] [3] It is not to be confused with Coccinella transversoguttata , a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together.
The transverse ladybird was first described by Danish zoologist Johan Christian Fabricius in 1781 as Coccinella transversalis and still bears its original name. Fabricius' description predated Carl Peter Thunberg's naming of this species as C. repanda by several months. [4]
Measuring 3.8 to 6.7 millimetres (0.15 to 0.26 in) long and 3.3 to 5.45 millimetres (0.130 to 0.215 in) wide, the transverse ladybird shows little variation across its wide range. [4] It has a black head with predominantly bright red or orange elytra boldly marked with a black band down the midline and two lateral three-lobed markings. [5]
Like many species of ladybirds, the transverse ladybird plays an important role in agriculture as it preys on a wide array of plant-eating insects which damage crops, particularly early in the growing season. [6] Among those insects hunted include many species of aphids, including the pea aphid ( Acyrthosiphon pisum ), Aphis affinis , cowpea aphid ( Aphis craccivora ), cotton aphid ( Aphis gossypii ), milkweed aphid ( Aphis nerii ), spirea aphid ( Aphis spiraecola ), leafcurling plum aphid ( Brachycaudus helichrysi ), cabbage aphid ( Brevicoryne brassicae ), Cervaphis quercus , Cervaphis rappardi indica , turnip aphid ( Lipaphis pseudobrassicae ), Macrosiphoniella yomogifoliae , potato aphid ( Macrosiphum euphorbiae ), rose aphid ( Macrosiphum rosae ), Melanaphis donacis , Melanaphis sacchari , Myzus nicotianae , green peach aphid ( Myzus persicae ), Pentalonia nigronervosa , corn aphid ( Rhopalosiphum maidis ), Sitobion rosaeiformis , Taoia indica , Toxoptera aurantii , Therioaphis ononidis , Therioaphis trifolii , Uroleucon compositae and Uroleucon sonchi , species of leafhopper including Empoascanara indica and Idioscopus clypealis , the scale insect species Orthezia insignis , the Asian citrus psyllid ( Diaphorina citri ), the cotton bollworm ( Helicoverpa armigera ), and oriental leafworm moth ( Spodoptera litura ).

The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors with the green peach aphid being one of the most prevalent and indiscriminate carriers.
Coccinella septempunctata, the seven-spot ladybird, is a carnivorous beetle native to the Old World and is the most common ladybird in Europe. Its elytra are of a red colour, but each punctuated with three black spots, with one further spot being spread over the junction of the two, making a total of seven spots, from which the species derives both its common and scientific names.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
Myzus persicae, known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops.
Coccinella undecimpunctata, the eleven-spot ladybird or eleven-spotted lady beetle, it is native to central Asia, though commonly found in Europe, and formerly North America as its populations are decreasing. It is of the family Coccinellidae, commonly referred to as ladybugs or lady beetles.
Calvia quatuordecimguttata, the cream-spot ladybird, is a species of ladybird in the family Coccinellidae. Its distribution is holarctic, it being found in Europe and through the East Palearctic to Japan. It is introduced to North America. This ladybird is generally 4 to 5 millimetres in length and varies in appearance depending on the geographical location. It usually lives in hedgerows and deciduous trees.
Micraspis discolor is a species of ladybird. It was described by Johan Christian Fabricius in 1798. It is widespread throughout Asia, North America and parts of Oceania.
Aphis affinis is an aphid of the family Aphididae. The species was described by Giacomo del Guercio in 1911. It is found in southern Europe, the Middle East and the Indian subcontinent. Ladybird predator species of A. affinis include Brumoides suturalis, Cheilomenes sexmaculata and Coccinella transversalis.
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.
Cheilomenes sexmaculata is a species of ladybird. Although sometimes known by the common name of six-spotted zigzag ladybird, this is misleading as there are several colour morphs and some colour morphs of the species can be confused with Micraspis discolor and Chilocorus nigrita. The species has a wide distribution range within the Asian tropics and subtropical zones from India to Japan and parts of the Australian region. They have been introduced into the Caribbean islands as a biocontrol agent and their spread to South America was noted in 2019. It is well known as a predator of aphids and other small insects.
Harmonia octomaculata is a species of ladybird of the family Coccinellidae. It is found throughout India, Pakistan, Nepal, Bangladesh, Sri Lanka, Micronesia, and Australia.
Anegleis cardoni, is a species of lady beetle found in India, Pakistan and Sri Lanka.
Illeis cincta, is a species of lady beetle native to India, Sri Lanka and Indonesia.
Propylea dissecta, is a species of lady beetle native to India, Sri Lanka, Bangladesh and Nepal.
Synonycha grandis, commonly known as Giant bamboo ladybird, is a species of lady beetle found in Australia, Oceania and Southern Asia.
Pseudaspidimerus trinotatus, is a species of lady beetle found in India, Sri Lanka and Myanmar.
Scymnus (Pullus) latemaculatus, is a species of lady beetle found in Pakistan, India, Bangladesh, Sri Lanka, Thailand, and Taiwan.
Scymnus (Scymnus) nubilus, is a species of lady beetle found in Pakistan, India, Bangladesh, Sri Lanka, Nepal, Myanmar, China, and Asia Minor.
Scymnus (Pullus) coccivora, is a species of lady beetle found in India, Bangladesh, Sri Lanka, Malaysia, and Pakistan and probably in Thailand, Bermuda, British Virgin Islands, Grenada, Saint Kitts and Nevis, Trinidad and Tobago and Papua New Guinea.
