Orange Ladybird

Halyzia sedecimguttata can reach a length of 5–6 millimetres (0.20–0.24 in). These beetles have an oval shaped body, rather round than elongated. Compound eyes are black. The antennae are light-brown, quite long and slightly thickened at the end. Their physical appearance is marked by a striking orange colour and the presence of 16 (sometimes less) creamy white large spots on the elytra (eight spots on each elytron). The neck shield usually covers the head and shows orange colored spots. A typical feature is the slightly transparent edges of the elytra. Transparent parts are also present on either side of the neck shield. This species is rather similar to Calvia decemguttata and Vibidia duodecimguttata.

Halyzia sedecimguttata is common in Europe, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Transcaucasia, Kazakhstan, Asia Minor, Mongolia, Northern China, Japan. It was formerly uncommon in the Ireland and Britain but the species has established itself over the 20th-century and it is now common in many parts.
