A moth species never before recorded in Europe has now made its debut in the Maltese Islands, specifically in Gozo. The Ficus-feeding erebid moth (Rhesala moestalis), originally found in tropical regions of Africa and Asia, has been officially identified in Gozo, marking its first known appearance on the continent.

The discovery was made during routine pest control inspections at a major pet supply shop, where the moth was found infesting rabbit feed. While it is believed that the insect likely arrived through imported ornamental Ficus plants, its detection in commercial feed demonstrates how invasive species can exploit unexpected pathways to establish themselves in new areas.

This nocturnal moth, classified under the Noctuidae family, is considered a potential pest due to the feeding behaviour of its larvae. These caterpillars consume the leaves of various Ficus species, including common plants like fig trees and rubber plants, raising concerns about the moth’s impact on both ornamental and agricultural vegetation.

The species was identified and collected by Arnold Sciberras, director of the Exterminator pest control company, with assistance from lepidopterist Jonathan Agius and team member Jeffrey Sciberras. Immediate action was taken to prevent further spread.

This finding highlights the importance of early detection and monitoring, especially as global trade and plant imports increase the risk of new species arriving in delicate ecosystems like Malta’s.
