Attelabinae
leaf-rolling weevils
Attelabinae is a subfamily of leaf-rolling weevils within the beetle family Attelabidae. It comprises at least 20 genera and over 690 described species. Members are characterized by specialized leaf-rolling behaviors used in reproduction, where females construct leaf rolls to protect eggs and developing larvae. The subfamily is distributed across North America from Canada to Panama, with documented host associations including chestnuts (Castanea) and various flowering plants.
Homoeolabus
leaf-rolling weevils
Homoeolabus is a genus of leaf-rolling weevils in the beetle family Attelabidae, established by Jekel in 1860. The genus contains at least two described species: Homoeolabus analis and Homoeolabus similis. Members of this genus are known for their distinctive nidification behavior involving the rolling of leaves to create protective structures for their eggs and larvae.
Homoeolabus analis
Leaf-rolling weevil, Oak leaf rolling weevil
Homoeolabus analis is a leaf-rolling weevil in the family Attelabidae, native to North America. The species is notable for its distinctive reproductive behavior: females cut and roll oak leaves into protective structures called nidi (singular: nidus) to shelter their eggs. This behavior, termed "nidification," is subject to kleptoparasitism by the thief weevil Pterocolus ovatus, which steals eggs from these leaf rolls. Despite their conspicuous leaf damage, populations generally cause minimal impact to host plant health.
