Classification

Lachninae: Cinarini

Common name(s)

Cypress pine aphid

Diagnosis

The aphid is reddish brown and dusted with white wax. The head is brown with a distinct median suture and hairs on frons and vertex are with acute apices. Two dark brown lines arising from head form an inverted fork-like marking on dorsum, which meet a transverse brown band joining siphunculi and continue still further up to cauda. All the appendages and abdominal terga are hairy. Siphunculi present on small hairy cones; cauda pale brown.

It is very difficult to detect the aphid colony on the plant as the aphid is cryptically coloured and camouflages with the plant twigs.

Host plant(s)

Cupressaceae: Thuja chilensis D.Don.
