Cover Story (view full-size image): In the last few years, a new pest, the black weevil Aclees taiwanensis Kȏno, 1933 (Coleoptera: Curculionidae), native to Asia, has been threatening fig orchards in the Mediterranean area. The black weevil xylophagous larvae, compromising the phloem flux, cause plant death. There are no known natural enemies of this pest and its rapid diffusion all over the Mediterranean area can reasonably be expected due to the lack of specific EU regulations. In-depth knowledge of black weevil biology is needed for the early detection and management of A. taiwanensis infestations. This paper describes, under laboratory and field conditions, the main biological traits of A. taiwanensis and updates the known distribution of this species in Southern Europe, using a citizen science approach.
