The Biology of (Lepidoptera: Oecophoridae), a Stem-Boring Moth of (Myrtaceae): Descriptions of the Previously Unknown Adult Female and Immature Stages, and Its Potential as a Biological Control Candidate.

is a perennial shrub native to Southeast Asia and is invasive in South Florida and Hawai'i, USA. During surveys of in Hong Kong from 2013-2018 for potential biological control agents, we collected larvae of the stem borer, . Larvae were shipped in stems to a USDA-ARS quarantine facility where they were reared and subjected to biology studies and preliminary host range examinations. is the most recent species to be described from males collected in Vietnam and Indonesia. Because the original species description was based on only two male specimens, we also provide a detailed description of the female, egg, larva, and pupa. Finally, we conducted preliminary host range trials utilizing , , and . emerged from a Florida-native shrub, and larvae were able to survive in non-target stems for over a year (>400 days). Based on these findings and difficulty in rearing, we do not believe is a suitable insect for biological control of at this time, but may warrant further study. This investigation also illustrates the importance of host surveys for conservation and taxonomic purposes.
