Solenosthedium bilunatum (Heteroptera: Scutelleridae) at the Adriatic Coast of Croatia

Nowadays, online social media provide rich insight into natural history and the distribution of many living beings. Based on citizen records uploaded to Facebook, we confirm the presence of the shield bug Solenosthedium bilunatum (Lefèbvre, 1827) in Croatia. S. bilunatum is a remarkable Mediterranean scutellerid within the subfamily Elvisurinae, with its distribution core in Southern Europe, the Middle East and North Africa. The species was recorded in Croatia only once prior to our study, in 2000 in Vela Luka on the Adriatic island of Korčula. We report the species from three additional localities in Dalmatia: Kaštel Lukšić (recorded in 2018 and 2019), Split (recorded in 2019) and Mount Srđ above Dubrovnik (recorded in 2019). The species has either been neglected or is rare. Due to global warming, it could spread its distribution area towards north.
