Ladybirds

Cycloneda sanguinea

Spotless lady beetle

Unlike most lady beetles, adults of this species carry no spots on their glossy orange-red wing covers, making the plain color itself the identifying clue.

WhereGardens, crop fields, open vegetation
Size4 to 6.5 mm body length
WhenFebruary to November

The spotless lady beetle has smooth, shiny wing covers ranging from orange to deep red with no spots, aside from a pale mark sometimes visible just behind the thorax. Each side of the black thorax carries an isolated pale yellow or white spot fully ringed by black, and the body is domed like other lady beetles, measuring about 4 to 6.5 mm long.

Both the larvae and adults hunt aphids and other soft-bodied insects, with a single adult female consuming roughly 300 aphids over her lifetime and each larva eating hundreds more as it develops. Several generations are produced each year in gardens, crop fields and wild vegetation wherever aphids are abundant.
