• Coccinella septempunctata

  seven-spot ladybird, seven-spotted ladybug, seven-spotted lady beetle, C-7

  Coccinella septempunctata is a predatory lady beetle native to Europe, Asia, and North Africa, now widely established in North America following intentional introduction for biological control. Adults measure 6.5–7.8 mm with distinctive red elytra bearing seven black spots. The species is among the most extensively studied coccinellids due to its importance in aphid biocontrol and its invasive success in new ranges. It completes up to five generations annually with a six-week development cycle from egg to adult.
