Craneiobia
Kieffer, 1913
Craneiobia is a of in the , established by Kieffer in 1913. The genus contains at least two described that induce distinctive tube-like on leaves of Cornus (dogwood) plants. These are specialized gall-formers with a narrow association.
Identification
Members of this can be recognized by their association with Cornus plants bearing tube-shaped leaf . are minute typical of , with reduced and long, bead-like . -level identification requires examination of larval gall or adult .
Habitat
Occurs in supporting Cornus , including forests, woodlands, and ornamental plantings where dogwoods are present.
Distribution
Recorded from Denmark, Norway, and Sweden; likely more widespread in regions where Cornus occur.
Diet
feed within induced on Cornus leaves; specific feeding mechanism within gall tissue is unknown.
Host Associations
- Cornus - tube-like leaf
Life Cycle
Induces on leaves; presumably has with , larval, pupal, and stages typical of , though specific details are unreported.
Behavior
Induces tube-like on leaves; larval development occurs within these structures.
Ecological Role
inducer; creates specialized microhabitats on Cornus leaves that may support associated and .
Human Relevance
Minor significance; may occasionally affect ornamental dogwoods but is not considered a major pest.
