Scymnus suturalis

It is a tiny (2mm. -2.5 2mm.) ladybird. The elytra which bear long, mainly backward-pointing hairs are red or chestnut brown usually with a dark brown mark behind the scutellum and extending along the median. It is common. In Central Europe it is a forest species which feeds on Coccoidea—it is associated with the scale Chionaspis salicis.[4] S. suturalis occurs in conifer (especially Pinus sylvestris and other Pinus species) and mixed forests, also in marshes, gardens, and parks. In Russia and Poland, it feeds on Adelgidae and other aphids on Pinus, less frequently, on Betula pendula and other Betula species and Ligustrum vulgare.[5][6] It was also found under flakes of bark, in moss on the trunks, and in the litter of coniferous trees.
