Bio-Ethology of in Sardinia (Italy), an Area of New Introduction.

, also known as European hornet, is a eusocial Vespidae originally from Eurasia that was accidentally introduced on the island of Sardinia (Italy) in 2010. Currently, its distribution is limited to the northern area of the island. Considering that a non-harmful species in its native region can exhibit invasive behaviour when established in new environments, bio-ethological observations were conducted to better understand whether could show invasive traits in Sardinia, which represents a new introduction area.
