AppearanceMeasuring 3.8 to 6.7 millimetres long and 3.3 to 5.45 millimetres wide, the Transverse Ladybird shows little variation across its wide range. It has a black head with predominantly bright red or orange elytra boldly marked with a black band down the midline and two lateral three-lobed markings.
NamingThe Transverse Ladybird was first described by Danish zoologist Johan Christian Fabricius in 1781 as ''Coccinella transversalis'' and still bears its original name. Fabricius' description predated Carl Peter Thunberg's naming of this species as ''C. repanda'' by several months.
