[1] Cinara confinis has been found feeding on species of fir (Abies), and also on cedar (Cedrus), spruce (Picea) and juniper (Juniperus).

[2] It has a Holarctic distribution and is found in temperate regions of Europe and Asia, in North America and Argentina.

[3] In Maine, wingless females known as fundatrices hatch out of over-wintering eggs in mid-May, at the base of buds near the top of small trees.

Colonies form just below the first whorl of shoots and the reproduction at first is parthenogenetic and viviparous with the offspring being wingless.

The wasp Pauesia grossa, found in Central Europe, is probably restricted to using Cinara confinis as a host in which to lay eggs.
