Two-Spotted Spider Mite (Tetranychus urticae)

These microscopic arachnids thrive in hot, dry conditions and feed on the sap of Abies needles, leaving behind characteristic fine silken webs. The damage typically manifests as stippling or bronzing of the needle tips.

Pacific Yew Psyllid (Psychomorpha)

While less common on Abies homolepis than on Taxus, certain psyllid species can produce fine webbing while feeding on new growth. This often results in distorted needles and localized webbing around developing buds.

Common

Spotted Webworm

The larvae of certain moth species create silk webs to protect themselves while feeding on the foliage of coniferous trees. This can lead to visible webbing and patches of defoliation as the larvae consume needle tissue.

Common
