Coleotichus blackburniae as they develop. This insect occurs on all the main islands of Hawaii. They are found on `a`ali`i ("Dodonaea viscosa") bushes and koa ("Acacia koa") trees. Also found on Formosan Koa (Acacia confusa) which is native to Southeast Asia. It has been commonly used in Hawaii as an ornamental landscape tree that has been deemed invasive. A. confusa and A. koa both have distinctive phyllodes that differentiate each species but since its introduction C. blackburniae has been recorded to associate with the invasive Formosan koa. Common to all true bugs, this species has no mouth parts with which to bite,
Acacia koa of their electric guitars as well, and still uses a koa-veneered topwood on certain models. Fender made limited edition koa wood models of the Telecaster and the Stratocaster in 2006. Trey Anastasio, guitarist for the band Phish, primarily uses a koa hollowbody Languedoc guitar. Commercial silviculture of koa takes 20 to 25 years before a tree is of useful size. Among other Pacific Islands of volcanic (non-continental) origin, only Vanuatu has native "Acacia" species. "A. heterophylla", from distant Réunion, is very similar and has been suggested to be the closest relative of koa. Genetic sequence analysis results announced in 2014
