About Adalia decempunctata (Linnaeus, 1758)
Adalia decempunctata, commonly known as the ten-spotted ladybird, can reach a body length of approximately 3.5–5 mm (0.14–0.20 in). This species is highly variable in appearance. Individuals can have a ground color that is red, orange, or brown, and between 0 and 12 distinct dark spots on their elytra; rarely, larger numbers of spots up to 15 have been recorded. These beetles have a glabrous, almost round body. Their legs and antennae are most commonly brown or orange. The species is divided into eight varieties, which fall into three basic forms. The light form has five to seven black spots on the pronotum, along with multiple black spots on its red-orange elytra. The dark form is primarily black or brown overall, with a light border along the sides and front of the pronotum. The mixed form has black or brown elytra, each of which bears five orange to red spots. Spots are sometimes completely absent in this species. Adalia decempunctata is a common Palearctic species distributed across Europe, North Africa, European Russia, the Caucasus, Siberia, Belarus, Ukraine, Moldova, Transcaucasia, and western Asia.
