Megachile sculpturalis (Smith, 1853) (Hymenoptera: Megachilidae) is an invasive solitary bee that is rapidly spreading all over Europe. The present study aims to update the distribution of this species in Italy. The research led to the collection of 177 records, obtained through bibliographic research and data-mining from websites, blogs and social networks. We here present the first record of M. sculpturalis on a Mediterranean island and discuss its possible effect on the native ecosystem. Given the particular discovery of M. sculpturalis on Elba Island (Tuscany), we suggest possible monitoring, containment and possible eradication measures of the species.

入侵性巨嘴Mega（膜翅目：巨翅目）在意大利的最新分布及其在地中海岛屿上的首次记录

Megachile sculpturalis（史密斯，1853年）（膜翅目：Megachilidae）是一种侵入性的单生蜂，正在欧洲迅速传播。本研究旨在更新该物种在意大利的分布。该研究收集了177条记录，这些记录是通过书目研究以及从网站，博客和社交网络进行的数据挖掘获得的。我们在此介绍地中海小岛上的M. sculpturalis的第一个记录，并讨论其对原生生态系统的可能影响。鉴于在厄尔巴岛（托斯卡纳）上特别发现了M. sculpturalis，我们建议对该物种进行可能的监视，控制和消除措施。
