Cream-spot ladybird - Calvia quatuordecimguttata - Maríuhæna - Flikrudepla - Bjalla - Skordýr

Cream-spot ladybird - Calvia quatuordecimguttata - Coccinella 14-guttata - Polkadot ladybird - Lady beetle - Coccinellidae - Maríuhæna - Maríubjalla - Flikrudepla - 14 doppu maríuhæna - on Sycamore maple flowers - Acer pseudoplatanus - Garðahlynur - Cowdray Park, Midhurst. Þessi fallega Maríubjalla er að gæða sér á blaðlús sem hún fann á blómum garðahlyns. Hlynur er einstofna tré með mjög breiða krónu sem getur orðið 500 ára gamall. Maroon-brown with fourteen cream-coloured spots. Found in forests of deciduous trees and shrubs. This species also lives amongst flowering plants that are present in dry grassland. The species occurs in a wide variety of habitats - 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 It is entomophagous feeding on aphids, Aleyrodidae, coccids, Coccoidea and on larvae and eggs of some beetles and butterflies. 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. They overwinter in leaf litter, crevices in the bark of trees and other similar protective locations. See more: https://en.wikipedia.org/wiki/Cream-s... 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. 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). There is no parental involvement besides the provisioning of eggs. Additionally, the eggs of C. quatuordecimguttata are coated with a compound that protects the eggs from predatory attacks by Harmonia axyridis. 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. See more: http://animaldiversity.org/accounts/C... The insect was unharmed in the making of this video. Unfortunately handheld, with such a macro and a minuscule depth of field the video is shaky and not always on focus. I filmed this flower with Panasonic Lumix DMC- TZ40 camera.
