Coccinellidae (/ˌkɒksɪˈnɛlɪˌdiː/)[3] is a widespread family of small beetles ranging in size from 0.8 to 18 mm (1⁄32–23⁄32 in).[4] The family is commonly known as ladybugs in North America and ladybirds in Great Britain and other parts of the English-speaking world. Entomologists prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs.[5]

The majority of the more than 6000 described species are generally considered beneficial insects, because many prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies in order to ensure their larvae have an immediate food source.[6] However, some species do have unwelcome effects; among these, the most prominent are of the subfamily Epilachninae (which includes the Mexican bean beetle), which are herbivorous themselves. Usually, epilachnines are only minor agricultural pests, eating the leaves of grain, potatoes, beans, and various other crops, but their numbers can increase exponentially in years when their natural enemies, such as parasitoid wasps that attack their eggs, are in fewer numbers. In such situations, they can do major crop damage. They occur in practically all the major crop-producing regions of temperate and tropical countries.

Etymology

The name coccinellids is derived from the Latin word coccineus meaning "scarlet".[7] The name ladybird originated in Britain where the insects became known as "Our Lady's bird" or the Lady beetle.[8][9] Mary (Our Lady) was often depicted wearing a red cloak in early paintings, and the spots of the seven-spot ladybird (the most common in Europe) were said to symbolise her seven joys and seven sorrows.[8][10] In the United States, the name was adapted to ladybug. Common names in some other European languages share associations; for example, the German name Marienkäfer translates to Marybeetle.[11]
Description

Coccinellids are often conspicuously coloured yellow, orange, or red with small black spots on their wing covers, with black legs, heads and antennae. There is, however, great variation in these colour patterns. For example, a minority of species, such as Vibidia duodecimguttata, a twelve-spotted species, have whitish spots on a brown background. Coccinellids are found worldwide, with over 6,000 species described.[12][4]
Clitostethus arcuatus larva, pupa and adults

Most coccinellids have round to elliptical, dome-shaped bodies with six short legs. Depending on the species, they can have spots, stripes, or no markings at all. Seven-spotted coccinellids are red or orange with three spots on each side and one in the middle; they have a black head with white patches on each side.

As well as the usual yellow and deep red colourings, many coccinellid species are mostly, or entirely, black, dark grey, gray, or brown.

Biology and distribution

Basic anatomy of a ladybird

Coccinellids are best known as predators of Sternorrhyncha such as aphids and scale insects, but the range of prey species that various Coccinellidae may attack is much wider. A genus of small black ladybirds, Stethorus, presents one example of predation on non-Sternorrhyncha; they specialise in mites as prey, notably Tetranychus spider mites. Stethorus species accordingly are important in certain examples of biological control.[13] They are natural predators of a range of serious pests, such as the European corn borer, a moth that costs US agriculture industry more than $1 billion annually in crop losses and population control.[14][15]

Various larger species of Coccinellidae attack caterpillars and larvae of other beetles.[13] Several genera feed on various insects or their eggs; for example, Coleomegilla species are significant predators of the eggs and larvae of moths such as species of Spodoptera and the Plutellidae.[16] Larvae and eggs of ladybirds, either their own or of other species, can also be an important food resource when alternative prey are scarce. As a family, the Coccinellidae used to be regarded as purely carnivorous,[17] but they are now known to be far more omnivorous than previously thought, both as a family and in individual species; examination of gut contents of apparently specialist predators commonly yield residues of pollen and other plant materials. Besides the prey they favour, most predatory coccinellids include other items in their diets, including honeydew, pollen, plant sap, nectar, and various fungi. The significance of such nonprey items in their diets is still under investigation and discussion.[18]

Apart from the generalist aphid and scale predators and incidental substances of botanical origin, many Coccinellidae do favour or even specialise in certain prey types. This makes some of them particularly valuable as agents in biological control programmes. Determination of specialisation need not be a trivial matter, though; for example the larva of the Vedalia ladybird Rodolia cardinalis is a specialist predator on a few species of Monophlebidae, in particular Icerya purchasi, which is the most notorious of the cottony cushion scale species. However, the adult R. cardinalis can subsist for some months on a wider range of insects plus some nectar.[19]

Certain species of coccinellids are thought to lay extra infertile eggs with the fertile eggs, apparently to provide a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. Such a strategy amounts to the production of trophic eggs.[20]

Some species in the subfamily Epilachninae are herbivores, and can be very destructive agricultural pests (e.g., the Mexican bean beetle). Again, in the subfamily Coccinellinae, members of the tribe Halyziini and the genus Tythaspis are mycophagous.

While predatory species are often used as biological control agents, introduced species of coccinellids are not necessarily benign. Species such as Harmonia axyridis or Coccinella septempunctata in North America outcompete and displace native coccinellids and become pests themselves.[21]

The main predators of coccinellids are usually birds, but they are also the prey of frogs, wasps, spiders, and dragonflies. The bright colours of many coccinellids discourage some potential predators from making a meal of them. This phenomenon, called aposematism, works because predators learn by experience to associate certain prey phenotypes with a bad taste. A further defence, known as "reflex bleeding", exists in which an alkaloid toxin is exuded through the joints of the exoskeleton, triggered by mechanical stimulation (such as by predator attack) in both larval and adult beetles, deterring feeding.

Coccinellids in temperate regions enter diapause during the winter, so they often are among the first insects to appear in the spring. Some species (e.g., Hippodamia convergens) gather into groups and move to higher elevations, such as a mountain, to enter diapause.

Most coccinellids overwinter as adults, aggregating on the south sides of large objects such as trees or houses during the winter months, dispersing in response to increasing day length in the spring.[22]

Predatory coccinellids are usually found on plants which harbour their prey. They lay their eggs near their prey, to increase the likelihood the larvae will find the prey easily. In Harmonia axyridis, eggs hatch in three to four days from clutches numbering from a few to several dozen. Depending on resource availability, the larvae pass through four instars over 10–14 days, after which pupation occurs. After a teneral period of several days, the adults become reproductively active and are able to reproduce again later, although they may become reproductively quiescent if eclosing late in the season. Total life span is one to two years on average.[23]
Population shift in Great Britain and Ireland

The atlas Ladybirds (Coccinellidae) of Britain and Ireland published in 2011[24] showed a decline of more than 20% in native species due to environmental changes and competition from foreign invaders. The distribution maps, compiled over a 20-year period with help from thousands of volunteers, showed a decline in the numbers of the common 10-spot and 14-spot ladybirds and a number of other species, including the 11-spot, 22-spot, cream-spot, water and hieroglyphic ladybirds, Coccidula rufa, Rhyzobius litura and Nephus redtenbacheri. Conversely, increases were seen in the numbers of harlequin, orange, pine, and 24-spot ladybirds, as well as Rhyzobius chrysomeloides. The kidney spot ladybird was recorded in Scotland for the first time in recent years, and the 13-spot was found to have recolonised Cornwall, Devon, and the New Forest. The most commonly recorded species was the 7-spot, closely followed by the Asian harlequin — an invader that arrived from continental Europe in 2003 after being introduced to control pests. An 'explosion' in the number of orange ladybirds, which feed on mildew, is thought to have been due to the warmer, damper conditions that now prevail in parts of England.[25]
Relationship to humans
Infestations
Coccinellids covering a branch

In North America, coccinellids usually begin to appear indoors in the autumn when they leave their summer feeding sites in fields, forests, and yards and search out places to spend the winter. Typically, when temperatures warm to the mid-60s °F (around 18 °C) in the late afternoon, following a period of cooler weather, they will swarm onto or into buildings illuminated by the sun. Swarms of coccinellids fly to buildings in September through November depending on location and weather conditions. Homes or other buildings near fields or woods are particularly prone to infestation.[26]

After an abnormally long period of hot, dry weather in the summer of 1976 in the UK, a marked increase in the aphid population was followed by a "plague" of ladybirds, with many reports of people being bitten as the supply of aphids dwindled.[27][28]

The presence of coccinellids in grape harvests can cause ladybird taint in wines produced from the grapes.[29]
As an invasive species

Harmonia axyridis (the harlequin ladybird) was introduced into North America from Asia in 1979 to control aphids, but it is now the most common species, outcompeting many of the native species.[30] It has since spread to much of western Europe, reaching the UK in 2004.[30][31] It has become something of a domestic and agricultural pest in some regions, and gives cause for ecological concern. It has similarly arrived in parts of Africa, where it has proved variously unwelcome, perhaps most prominently in vine-related crops.[32]
In culture
Card cutout ladybirds for a children's nature trail

Ladybirds have long been of interest to children. They had many regional names (now mostly disused) in English, such as variations on Bishop-Barnaby (Norfolk and Suffolk dialect) – Barnabee, Burnabee, the Bishop-that-burneth, and bishy bishy barnabee.[33][34] The etymology is unclear, but it may be from St. Barnabas' feast in June, when the insect appears, or a corruption of "Bishop-that-burneth", from the fiery elytra of the beetles.[35]

The ladybird was immortalised in the popular children's nursery rhyme Ladybird Ladybird:

Ladybird, ladybird, fly away home
Your house is on fire and your children are gone
All except one, and that's Little Anne
For she has crept under the warming pan.

This poem has its counterpart in German as Marienwürmchen, collected in Des Knaben Wunderhorn, and set to music by Robert Schumann as Op. 79, No. 13, and a Polish nursery rhyme, "Little Ladybirds' Anthem", of which a part ("fly to the sky, little ladybird, bring me a piece of bread") became a saying.[36]

Many cultures consider ladybirds lucky and have nursery rhymes or local names for the insects that reflect this. For instance, the Turkish name for the insect is uğur böceği, literally meaning 'good luck bug'. In many countries, including Russia, Turkey, and Italy, the sight of a coccinellid is either a call to make a wish or a sign that a wish will soon be granted.

In Christian areas, they are often associated with the Virgin Mary, and the name that the insect bears in the various languages of Europe corresponds to this. Although historically many European languages referenced Freyja, the fertility goddess of Norse mythology, in the names, the Virgin Mary has now largely supplanted her, so that, for example, freyjuhœna (Old Norse) and Frouehenge have been changed into marihøne (Norwegian) and Marienkäfer (German), which corresponds with Our Lady's bird.[37] Sometimes, the insect is referred to as belonging directly to God (Irish bóín Dé, Polish boża krówka, Russian божья коровка [bozhya korovka], all meaning 'God's [little] cow').[38] In Dutch it is called lieveheersbeestje, meaning 'little animal of our Good Lord'. In both Hebrew and Yiddish, it is called "Moshe Rabbenu's (i.e., Moses's) little cow" or "little horse", apparently an adaptation from Slavic languages. Occasionally, it is called "little Messiah".[39]

The insects have been used to symbolise Ladybird Books (part of Penguin Group),[40][41] and the Ladybird range of children's clothing sold by the former high street chain Woolworth's in the UK,[42] while the ladybird street tile is a symbol against senseless violence in the Netherlands, and is often placed on the sites of deadly crimes.[43] They have also been adopted as the mascot of Candanchú,[44] a ski resort near Canfranc in the Spanish Pyrenees. The ladybird also serves as a long-standing symbol for the Swedish People's Party of Finland.[45] Ladybirds have served as the US state insects of Delaware, Massachusetts, New Hampshire, New York, Ohio, and Tennessee, though only New York has selected a species native to the United States (Coccinella novemnotata); the other states have all adopted an invasive European species (Coccinella septempunctata).[46]
