A black species with a red spot on the rear of each wing case.
As with other Nephus species lacks a prosternal keel.

Pronotum is matt black.
Usually has two red spots on the rear of the wing cases.
The centre of the spots occur at three quarters of the wing case length.
The spots are usually small and obscure, with smeared margins.
Sometimes unspotted, therefore appearing all black.

Similar species
(See also Confusing Species Groups section above)
In spring 2025 a specimen of Nephus bipunctatus was photographed in southern England.
This species is very similar to Rear-spot Ladybird. The identification was considered to be this species but not confirmed.
I have used the vernacular name Twin-spot Ladybird for Nephus bipunctatus.
It is not currently on the British list.
Very similar to Rear-spot Ladybird. Main differences include:
Glossy black pronotum.
The centre of the spots occur at two thirds of wing case length.
Spots usually large, rounded or rectangular, distance between the spots equal or narrower than their diameter.
Spots rarely absent.
The humeral tubercles (squared raised bump on shoulder area) prominent.
Strongly waved hair pattern on wing cases.
Twin-spot Ladybird is used for biological control so more specimens could occur anywhere.
Described as widespread but uncommon on the continent.
Occurs in woodland and forest edges in shrubs and herbs.
Feeds on mealybugs.
