Seven-spotted Lady Beetle

Coccinella septempunctata

''Coccinella septempunctata'', the seven-spot ladybird, is the most common ladybird in Europe. Its elytra are of a red colour, but punctuated with three black spots each, 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.
Coccinella septempunctata - w. parasite? While in the field and quickly taking some shots of what appeared to be a wet and damaged individual I didn't pay enough attention, but looking at the photos it would seem this one may well have been carrying some endoparasite - the wings seem to be pressed appart by the bloated abdomen. In hindsight there were more individuals at the same location with similar "damage" (hind wings sticking out and elytra slightly open).
Will go back and try to find one or two and let it "develop".  Coccinella,Coccinella septempunctata,Coccinellidae,Coccinellinae,Coleoptera,Geotagged,Netherlands,Seven-spotted Lady Beetle,nl: Zevenstippelig lieveheersbeestje,parasitism


An adult seven-spot ladybird may reach a body length of 7.6–10.0 mm. Their distinctive spots and attractive colours apparently make them unappealing to predators. The species can secrete a fluid from joints in their legs which gives them a foul taste.

A threatened ladybird may both play dead and secrete the unappetising substance to protect itself. 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 insect is to potential predators.

It can be found in Europe, North Africa, Australia, Cyprus, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Moldova, the Transcaucasia, Kazakhstan, Middle Asia, Western Asia, Middle East, Afghanistan, Mongolia, China, North and South Korea, Pakistan, Nepal, North India, Japan and southeast Asia. It can also be found in North America and tropical Africa.

The first record of successful establishment in the United States was in 1973. It's since spread by natural dispersion to New York and Connecticut and to Oklahoma, Georgia and Delaware by recolonization.

''C. septempunctata'' has a broad ecological range, generally living where there are aphids for it to eat. and including, amongst other biotopes meadows, fields, Pontic–Caspian steppe, parkland, gardens, Western European broadleaf forests and mixed forests. Both the adults and the larvae are voracious predators of aphids, and because of this, ''C. septempunctata'' has been repeatedly introduced to North America as a biological control agent to reduce aphid numbers, and is now established in North America. It has been designated the official state insect of five different states.

Although ''C. septempunctata'' is mainly aphidophagous it also feeds on Thysanoptera, Aleyrodidae, on the larvae of Psyllidae and Cicadellidae, and on eggs and larvae of some beetles and butterflies. There are one or two generations per year. Adults overwinter in ground litter parks, gardens, and forest edges, of treelines, and under the tree bark and rocks.

In the United Kingdom, there are fears that the seven-spot ladybird is being outcompeted for food by the harlequin ladybird. Conversely, in North America, this species has outcompeted many native species, including other ''Coccinella''. Massive swarms of ''C. punctata'' took place in the drought summer of 1976 in the UK. The species has undergone significant declines on the island of Malta, yet it is unclear whether this decline has occurred at the same rate elsewhere.
