Cavariella konoi

Distinguished from other Cavariella species by the combination of pale yellowish green coloration with possible darker green longitudinal bands, host association with willow and Angelica atropurpurea, and holarctic distribution. Specific identification within the genus may require examination of morphological characters not detailed in available sources.

Associated with host plants: willow (Salix spp.) leaves in summer, and great angelica (Angelica atropurpurea). Specific habitat conditions beyond host plant presence are not documented.

Holarctic distribution. Confirmed present in Denmark, Norway, and Sweden based on GBIF records.

Wingless females active on willow leaves during summer; specific timing of other life stages or host alternation periods not documented.

Phloem feeder on willow (Salix spp.) and great angelica (Angelica atropurpurea).

• Salix - primary hostSummer feeding site for wingless females
• Angelica atropurpurea - secondary hostAlso known as great angelica

Reproduces parthenogenetically during summer on willow. Host alternation between willow and Angelica atropurpurea is indicated, though specific details of the complete life cycle are not documented.

Forms large populations on willow leaves during summer. Wingless females are the observed summer morph.
