The seven-spot ladybird synthesizes the toxic alkaloids, N-oxide coccinelline and its free base precoccinelline depending on sex and diet, the spot size and coloration can provide some indication of how toxic the individual bug is to potential predators. A threatened ladybird may both play dead and secrete the unappetising substance to protect itself. The species can secrete a fluid from joints in their legs which gives them a foul taste. Der Siebenfleckige MarienkГ¤fer ( Coccinella septempunctata) ist eine in Europa verbreitete Art des palГ¤arktischen MarienkГ¤fers.Die Spitznamen bГЄte Г bon Dieu seit dem Mittelalter wird es als GlГјcksbringer gesehen und hat oft Spitznamen mit religiГ¶sen Konnotationen: Madonnas Henne in Italien, Mary SkarabГ¤us oder Herrn KГ¤lbchen auf Deutsch (in Deutsch. Their distinctive spots and attractive colours apparently make them unappealing to predators. Anatomy and physiologyДЄn adult seven-spot ladybird may reach a body length of 7.6вЂ“10.0 mm (0.3вЂ“0.4 in). In Slovenia it is rare and endangered, with a status of E- affected species and. punctata took place in the drought summer of 1976 in the UK. melolontha) and seven-spot ladybird (Coccinella septempunctata). The surface of the dung beetles head varies, but it is short, broad, and partially deflexed. These leaves can be expanded or folded together to form one compact club. This antennae forms a club containing three to seven leaves. Conversely, in North America, this species has outcompeted many native species, including other Coccinella. The most distinctive feature is the segmented antennae. Factors were examined that could be responsible for the predominance of Coccinella septempunctata (C7) in most habitats of the Palaearctic and for its successful invasion of the Nearctic Region. In the United Kingdom, there are fears that the seven-spot ladybird is being outcompeted for food by the harlequin ladybird. Why is Coccinella septempunctata so successful (A point-of-view) Ivo HODEK, J.P. septempunctata, the distribution is not in relation with the possibility of development of progeny, while the adults of O.

pusilla (Dipt., Chloropidae) on potato: Leptinotarsa decemlineata (Col., Chrysomelidae) and Coccinella septempuncВ tata (Col., Coccinellidae).

C7 is euryphagous, but less polyphagous than Harmonia axyridis or Coleomegilla maculata in that it cannot develop or reproduce on non-aphid food. septempunctata has been repeatedly introduced to North America as a biological control agent to reduce aphid numbers, and is now established in North America, and has been subsequently designated the official state insect of five different states ( Delaware, Massachusetts, New Hampshire, Ohio, and Tennessee). The insects studied were on cereals: Oscinella frit and O. Factors were examined that could be responsible for the predominance of Coccinella septempunctata (C7) in most habitats of the Palaearctic and for its successful invasion of the Nearctic Region.

Both the adults and the larvae are voracious predators of aphids, and because of this, C. septempunctata has a broad ecological range, living almost anywhere there are aphids for it to eat.
