Synonyms and other taxonomic changes
Coccinella septempunctata Linnaeus
Orig. Comb: Coccinella 7-punctata Linnaeus, 1758
Explanation of Names
septempunctata - Latin for "7-pointed", referring to the 7 black spots on the elytra
Size
6.5-7.8 mm (1)
Identification
Adults comparatively large (7-8 mm) with a white or pale spot on either side of the head.

Larva black with orange markings:
Range
throughout N. Amer. and most of the Old World - Map - Discover Life
the most common lady beetle in Europe
Habitat
may be present in agro-ecosystems (2)
Life Cycle
1. Eggs. 2. Firt instar larvae. 3 and 4. Later instars. 5. Pupa. 6. Teneral adult
Remarks
It has been repeatedly introduced in the US from Europe, to control aphids.
This widespread palearctic species was intentionally introduced into N. America several times from 1956 to 1971 for biological control of aphids. All of those attempts apparently failed in getting C. septempunctata established, but in 1973 an established population was found in Bergen Co., New Jersey. This population is thought to have been the result of an accidental introduction rather than a purposeful one (Angalet and Jacques, 1975). Since 1973, this species has spread naturally and been colonized and established in Delaware, Georgia, and Oklahoma. (Gordon 1985)
It has since spread throughout N. Amer.
