Seasonal occurrence and host-lists of Hawaiian Cerambycidae

Abstract

The cerambycid beetle borers play an important role in Hawaiian forests, both in the natural and disturbed environments. Their significance is enhanced by the disharmonic nature of the fauna, such as the lack of leaf beetles and june beetles, in the native fauna. There are about 120 known species of endemic cerambycids, almost entirely restricted to native trees and shrubs, and 17 species of established exotic cerambycids, which with few exceptions bore in exotic trees. The seasonal occurrence, as far as known of the adult cerambycids is tabulated. Altitudinal range and latest year of collection (native) or earliest year of record (exotic) are also tabulated. In a further tabulation, the species for which host associations are known are presented by host genera under plant families, and by islands. The introduced species are treated in similar manner.
