Intraspecific and interspecific predation of the eggs of Calvia quatuordecimguttata is common. Harmonia axyridis is an invasive coccinellid that is known to eat the eggs of many other coccinellids. Calvia quatuordecimguttata is well protected against the attack of Harmonia axyridis due to a compound that coats the outer surface of its eggs. The effect of this compound may be due to the abundance of hydrocarbons on the coating of the egg as well as the presence of alkenes. There are also patches of a red substance that coat the eggs, which is believed to be a type of acid. As a coccinellid, C. quatuordecimguttata can likely reflex bleed, emitting toxins from joints in the exoskeleton when threatened. The different colorations and elytral patterns function as a warning sign to predators.

Known Predators:

  • Harmonia axyridis

Anti-predator Adaptations: aposematic

Morphology

provided by Animal Diversity Web

Calvia quatuordecimguttata, which is commonly referred to as the cream-spotted lady beetle, is polymorphic and shows great variety in coloration and elytral patterns. In North America, C. quatuordecimguttata was documented to have three different elytral patterns: black with 14 white spots, black with 2 or 4 red spots, and orange with 12 black spots. Other documented forms are maroon-brown in color. C. quatuordecimguttata ranges in length from 3.50 to 5.50 mm and it is oval in form and weakly convex. The intercoxal process of the prosternum is smooth and slightly convex with a weak lateral ridge that extends anteriorly as far as the anterior margin of the coxa. C. quatuordecimguttata has 2 spurs on the apex of the middle and hind tibia.

Range length: 3.5 to 5.5 mm.

Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry ; polymorphic ; poisonous

Sexual Dimorphism: sexes alike

Life Expectancy

provided by Animal Diversity Web

Eggs of C. quatuordecimguttata are laid in spring, as early as March. The time of development from egg to adult depends on temperature, taking about 14 days at warmer temperatures, while taking up to 115 days at lower temperatures. Adults live for an extended period after that through summer (several more weeks or months), until temperatures cool in the fall and adults enter diapause, emerging again the following spring.

Life Cycle

provided by Animal Diversity Web

Eggs are laid in the early spring by adults that have overwintered. After larvae emerge and then pupate, like other Coccinellidae, adults live for a few weeks in the summer until the weather cools. The final generation overwinters as diapause occurs. Adults of C. quatuordecimguttata cannot mate and reproduce until after emerging from diapause in the spring. Development of C. quatuordecimguttata is temperature dependent, with beetles that develop at lower temperatures reaching a greater size. The time of development from egg to adult is also temperature dependent, taking about 14 days at 30 degrees Celsius, while taking up to 115 days at lower temperatures (10 degrees Celsius).

Development - Life Cycle: metamorphosis ; diapause

Calvia quatuordecimguttata

provided by wikipedia EN

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 (0.16 to 0.20 in) in length and varies in appearance depending on the geographical location. It usually lives in hedgerows and deciduous trees.

Taxonomy

This ladybird was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae as Coccinella 14-guttata. As ladybirds were further studied, it was transferred to the genus Calvia which was erected in 1873 by the French entomologist Étienne Mulsant.[2] The specific name comes from quatuordecim, the Latin for "fourteen" and guttata, the Latin for "spotted".[1]

This ladybird is also sometimes known as the cream-spotted ladybird, polkadot ladybird or eighteen spot ladybird and may be confused with another beetle also known as the eighteen-spot ladybird (Myrrha octodecimguttata). The latter is usually found on pine trees and is smaller and a paler brown colour and has a characteristic M-shaped white mark on its pronotum.[3]

Description

Pair of mating ladybirds

The cream-spot ladybird measures 4 to 5.5 millimetres (0.16 to 0.22 in) long and 3.2 to 4.5 millimetres (0.13 to 0.18 in) broad. It is very variable in colouration in North America. In Europe the species is consistently maroon-brown with fourteen cream-coloured spots, but in North America and parts of eastern temperate Asia it occurs in several other colour forms. It may be black with white spots (similar to the European form but darker), or anywhere from yellow to pink with 18 large blotches. An excessively melanistic version exists that is all black with a large red-orange patch on each elytron. It always has a glossy pronotum and the underside of the beetle has a thin red rim to the otherwise black abdominal segments.[1][4]

The larvae are black with white markings, have six legs and several blunt conical spines on each segment of the abdomen, similar to larvae of Cycloneda but with shorter legs.[1]

Distribution

The cream-spot ladybird has a holarctic distribution. In North America the range extends from Alaska and Labrador south to California and New Jersey,[1] where it is introduced. The Palearctic range is Europe, North Africa, Cyprus, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Moldova, Transcaucasia, Kazakhstan, western Asia, Pakistan, Mongolia, China, and Japan.[5][6][7] It is present throughout Britain and Ireland though more common in England than further west and north.[8]

Ecology

The species occurs in a wide variety of environments – deciduous and mixed forests for instance in Western European broadleaf forests, in ruderal areas, in parks, gardens, and meadows on grasses, bushes, and trees. It is also found in forest litter, on brushwood, in moss, in coarse woody debris and compost.[9] It is entomophagous feeding on aphids, Aleyrodidae, coccids, Coccoidea and on larvae and eggs of some beetles and butterflies.[10][11]

In a study it was found that their preferred prey aphids included the aspen leaf aphid Chaitophorus tremulae, the angelica aphid Cavariella konoi, the small willow aphid Aphis farinosa, the lime-tree aphid Eucallipterus tiliae, the birch aphid Euceraphis betulae and the mugwort aphid Macrosiphoniella artemisiae.[12] They overwinter in leaf litter, crevices in the bark of trees and other similar protective locations.[4]

Gielas czternastoplamek, biedronka czternastokropka (Calvia quatuordecimguttata) – gatunek chrząszcza z rodziny biedronkowatych. Występuje w Holarktyce.

Taksonomia

Gatunek ten opisany został w 1758 roku przez Karola Linneusza w dziesiątej edycji Systema Naturae jako Coccinella 14-guttata. Z powodu szerokiego zasięgu występowania i dużego polimorfizmu w ubarwieniu doczekał się licznych synonimów – wiele jego form opisywanych było jako odrębne gatunki, podgatunki, odmiany i aberracje[2].

Opis

Owad dorosły

Chrząszcz o okrągławym, niezbyt mocno wypukłym ciele od 4 do 5,5 mm (wg Bielawskiego od 4,5 do 6 mm[3]) i szerokości od 3,2 do 4,5 mm. Ubarwienie wierzchu ciała bardzo zmienne, o tle ciemnym lub jasnym[2]. Osobniki spotykane w Polsce mają ciało brunatnawe z białymi plamami na przedpleczu, a na każdej pokrywie jedną plamę przytarczkową i po trzy w drugim i trzecim szeregu[3].

Larwa

Głowa z wyraźnymi szwami czołowymi. Aparat gębowy z żuwaczkami wyposażonymi w retinaculum, a u wierzchołka podzielonymi na dwa zęby. Terga śródtułowia i zatułowia z dwoma sklerytami. Odwłok o tergach od pierwszego do siódmego wyposażonych w coraz dłuższe senta grzbietowe; na tergach od czwartego do ósmego są one długie. Dziewiąty tergit odwłoka ma drobny, skierowany w tył wyrostek położony na tylnej krawędzi[4].

Występowanie

Zasiedla tereny nizinne i niższe położenia górskie. Zimuje w ściółce, wśród mchów i opadłych liści. Pojawia się wczesną wiosną na krzewach i drzewach liściastych, również na kwitnących czeremchach i tarninach[5].

Występuje w Europa, północna część Afryki, Azja, z wyjątkiem części południowej oraz prawie cała Ameryka Północna[5][2].

Fjortonfläckig nyckelpiga ( Swedish )

provided by wikipedia SV

Fjortonfläckig nyckelpiga (Calvia quatuordecimguttata), även skrivet som 14-fläckig nyckelpiga, är en art i insektsordningen skalbaggar som tillhör familjen nyckelpigor.

Kännetecken

Den fjortonfläckiga nyckelpigan har den för nyckelpigorna typiska breda, ovala och välvda kroppsformen och en längd på cirka 4,5 till 6 millimeter. Täckvingarna är vanligen gulbrunaktiga med ljusare, vitaktiga fläckar. På varje täckvinge finns sju fläckar, varav fyra är parvis placerade i en rad på ömse sidor av sutur, sömmen mellan täckvingarna. Sammantaget uppgår antalet fläckar på täckvingarna därför till fjorton, vilket också artens trivialnamn syftar på. Även halsskölden är gulbrunaktig, med vitaktiga bakhörn, och det är också antenner och ben.

Utbredning

Den fjortonfläckiga nyckelpigan förekommer i den palearktiska regionen, i Europa och delar av norra Asien, samt i Nordamerika. Den saknas dock i dessa områdens allra nordligaste trakter.

Levnadssätt

Den fjortonfläckiga nyckelpigan kan hittas i både torrare och mer fuktiga miljöer, exempelvis skogsbryn och ängar. Dess föda både som larv och imago består av till stor del av bladlöss, men även av bladloppor. Övervintringen sker som fullbildad skalbagge i jorden.

Четырнадцатипятнистая коровка[1] (Calvia quatuordecimguttata) — вид божьих коровок из подсемейства Coccinellinae.

Описание

Жуки примерно от 4,5 до 6 мм длиной, с широким, овальным и выпуклым телом. Их надкрылья от светло-коричневого до коричнево-красного с семью беловатыми пятнами, попарно расположенными по обе стороны от центра в четыре ряда. Грудной щит красновато-коричневый. Оба усика и ноги коричневые.

Распространение

Жуки встречаются во всей Палеарктике и Северной Америке, но отсутствуют в районах Крайнего Севера. Обитают как во влажных, так и на сухих участках, таких как опушки леса и луга.

Образ жизни

Зимуют жуки в почве. Как и большинство видов божьих коровок питаются как личинки, так и взрослые особи тлёй, а также листоблошками.
