About Xyleborus dubiosus
Xyleborus dubiosus is a member of Curculionidae in the order Coleoptera. Its recorded origin status on Kauaʻi is endemic hawaiian.
Xyleborus dubiosus is a native Hawaiian ambrosia beetle newly documented from Kauaʻi in ʻōhiʻa forest trapping associated with rapid ʻōhiʻa death research.
Kauaʻi occurrence evidence: Roy et al. (2023) report Xyleborus dubiosus as a new Kauaʻi island record from trap captures in mixed ʻōhiʻa forest and identify it as a native Xyleborus.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; larva; pupa; adult; gallery-associated development in woody substrate typical of ambrosia/pinhole beetles; species-specific timing remains to be sourced.
Habitat
Kauaʻi mixed ʻōhiʻa forest / rapid ʻōhiʻa death study sites; species-specific host breadth and microhabitat require further source extraction.
Food and ecological role
Wood-boring/gallery beetle associated with symbiotic fungi; exact host and fungal associations on Kauaʻi require species-specific completion.
Reproduction
Breeding occurs in galleries excavated in woody material; species-specific mating system and brood details remain to be sourced.
Movement
Adults disperse by flight; Kauaʻi dispersal distances and seasonal flight patterns require species-specific evidence.
Ecosystem role
Native hawaiian wood-associated ambrosia/pinhole beetle in Kauaʻi forest arthropod communities.
Monitoring
Lock exact collection localities/specimen details where available, current-name authority, host associations, and exact-taxon public reference media/license.
