Distribution
North America, ranging from Canada through the Republic of Panama. Specific distribution data derives from documented records for member rather than comprehensive -level surveys.
Host Associations
- Castanea dentata - plantDocumented for Homoeolabus analis; leaf-rolling observed on this
- Salvia melissodora - plantDocumented for Pilolabus klugi through field observations and voucher specimens
Life Cycle
Females construct leaf rolls (nidification) for deposition. Larval development occurs within these protective leaf structures.
Behavior
Unique nidification involving leaf-rolling: females cut and roll leaf material to create protective chambers for . This behavior is a defining characteristic of the group.
Similar Taxa
- RhynchitidaeEcologically associated; thief weevils in Pterocolinae (formerly Rhynchitidae) exhibit kleptoparasitic relationships with Attelabinae, exploiting their leaf rolls
More Details
Taxonomic scope
Most detailed biological information available for Attelabinae pertains to specific, well-studied (e.g., Homoeolabus analis, Pilolabus klugi) rather than the as a whole. Generalizations to the entire subfamily should be made cautiously.
Species diversity
With over 690 described across at least 20 , Attelabinae represents a diverse lineage, but many species remain poorly known biologically.
