Cinara curvipes
Bow-legged Fir Aphid
Cinara curvipes is a large, black bark aphid native to North America that has become invasive in Central Europe since 2000. Adults measure 4.5–5.3 mm. The species exhibits remarkable life cycle flexibility, with populations capable of both holocyclic (sexual) and anholocyclic (parthenogenetic) reproduction. In its invaded range, it can form exceptionally large colonies of thousands of individuals by May—a phenomenon not observed in native European Cinara species. The aphid secretes copious honeydew throughout most of the year, supporting diverse insect communities.
Pterocomma bicolor
Reddish-brown Willow Bark Aphid
Pterocomma bicolor is a species of aphid in the family Aphididae, commonly known as the Reddish-brown Willow Bark Aphid. It was described by Oestlund in 1887. The species belongs to the tribe Macrosiphini within the subfamily Aphidinae. As a member of the genus Pterocomma, it is associated with willow (Salix) host plants, though specific biological details remain poorly documented in available literature.
Pterocomma rufipes
Rufous Willow Bark Aphid
Pterocomma rufipes is a species of bark-feeding aphid in the family Aphididae, originally described from Europe by Hartig in 1841. The species is associated with willow (Salix) hosts and is characterized by its reddish leg coloration, referenced in its specific epithet. As a member of the genus Pterocomma, it exhibits the typical morphology of bark-dwelling aphids with reduced cornicles and a flattened body form adapted to living in crevices.
