About Fruit-tree Pinhole Borer
Fruit-tree Pinhole Borer (Xyleborinus saxesenii) is a member of Curculionidae in the order Coleoptera. Its recorded origin status on Kauaʻi is introduced / adventive.
Fruit-tree Pinhole Borer (Xyleborinus saxesenii) is an introduced ambrosia beetle documented from Kauaʻi ʻōhiʻa forests. It was among the beetles reared or trapped in the Kauaʻi rapid ʻōhiʻa death study.
Kauaʻi occurrence evidence: Roy et al. (2023) list Xyleborinus saxesenii among beetles associated with rapid ʻōhiʻa death on Kauaʻi. Gómez et al. (2018) use saxesenii based on the original spelling; ITIS currently uses saxeseni, so the spelling conflict is preserved in the alias audit.
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
Documented in Kauaʻi ʻōhiʻa forest rapid ʻōhiʻa death investigations; wood/host associations beyond the study system require species-specific completion.
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
Introduced 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.
