Habitat
Temperate climate zones. At least some complete part of their in soil, where propupal and pupal stages moult.
Distribution
Recorded from Norway, Sweden, and Vermont, United States. occur across North America, Europe, and Asia (China, Japan, India).
Diet
For Ctenothrips distinctus: epidermal of leaf blades, feeding on both upper and lower leaf surfaces. plant associations documented for this include Convallaria majalis (Lily of the Valley).
Host Associations
- Convallaria majalis - plantDocumented for Ctenothrips distinctus; both and larvae feed on leaf epidermal
Life Cycle
Preimaginal stages include larval instars, propupa, and pupa. In Ctenothrips distinctus, the propupa and pupa possess morphological adaptations for moulting in soil rather than on the plant.
Behavior
Feeding occurs on leaf epidermal . takes place in soil, not on the plant.
Ecological Role
Herbivore causing feeding damage to plant foliage. Feeding affects epidermal while underlying assimilation parenchyma cells at feeding sites retain their shape.
