Red-flanked Scymnus (Scymnus interruptus)
This is an absolutely tiny ladybird measuring just 1.5-2mm in length, which might account for the relatively low number of NBN records.
Scymnus interruptus comes in both a dark and light form, with the former being by far the most common with a variably-sized red triangle on each wing case. The light form has a greater covering of red over the wing cases in various shapes. Both form ave red legs and antennae.
Males usually have a red face and pronotum while those of the females are generally black.
Although similar to a some other ladybird species a diagnostic feature is that the red triangles on the wing cases extend to the very edges and quite often to the underside of the epipleuron.
This can be seen in the lower of the two photos in the collage above.
This species can be found in gardens and elsewhere on evergreen shrubs, such as Euonymus, Privet, Viburnum tinus and (as in this case) Ivy, although you have to look VERY closely to find one without sweeping or beating, neither of which I do.
It can also be found on deciduous trees and shrubs, such as Oak and Wiegela.
Given its diminutive size,
''Scymnus interruptus'' is a species of beetle of the family Coccinellidae. This species is native to the West Palearctic region, but it was introduced into the United States as a biological control agent and then spread to other regions of the New World. It has been recorded in South America .
