Kauaʻi Swamp Long-horned Beetle

Natural history and identification

Plagithmysus paludis is a Kauaʻi longhorn beetle whose host remained unresolved in the historical host index. A later diagram suggested Alphitonia, but marked that association with a question mark. The proposed plant should not be presented as a verified larval host. Similarly, the common name “swamp long-horned beetle” does not demonstrate an aquatic larval stage. The useful distinction is between a documented island occurrence and a still-uncertain developmental substrate.

Kauaʻi occurrence and evidence

Atlas occurrence category: Present. The Kauaʻi record is classified as “Present”. Its cited evidence source is U.S. Fish & Wildlife Service / Hawaiʻi DLNR. Kauaʻi-specific conservation taxon retained even if absent from the surfaced modern observation tranche.

Evidence limits

The cited observations describe the evidence currently available for this account. They do not establish a complete life history or a measured current Kauaʻi population trend.
