Habitat

Associated with grassdominated environments including ornamental plantings and natural grasslands. Greenhouse studies indicate establishment on potted ornamental grasses.

Distribution

Documented from Central America and North America. GBIF records indicate presence in Alabama, Arizona, Florida, and Kansas. Specific new distribution records were reported in a 2007 study, though exact localities were not detailed in available excerpts.

Diet

Phloem feeder on grasses. Nochoice feeding studies demonstrated that Pennisetum sustained the highest damage levels and were the only supporting . Acorus, Cordyline, and Panicum species exhibited comparatively lower damage susceptibility.

Host Associations

Pennisetum purpureum - primary - supports feeding damage and highest susceptibility among tested grasses
Pennisetum spp. - primary - supports feeding damage and only supporting in greenhouse trials
Acorus spp. - secondary - low susceptibilityminimal damage in feeding trials
Cordyline spp. - secondary - low susceptibilityminimal damage in feeding trials
Panicum spp. - secondary - low susceptibilityminimal damage in feeding trials

Human Relevance

Emerging pest in southern U.S. horticulture, particularly affecting ornamental grass production. Damage manifests as characteristic stippling from phloem feeding. No plants tested showed complete , complicating management recommendations.
