An Overview of Orthoptera Mass Occurrences in Croatia from 1900 to 2023.

During the last century, well-known locust species, such as and , have produced outbreaks of varying degrees in the Balkans. The literature data on outbreaks in the region are scarce, and Croatia is not an exception. This study summarized the data on 23 Orthoptera mass occurrences in Croatia from 1900 to 2023 from 28 localities, representing 12 species.

The Balkan peninsula is an important biogeographic region of Europe which houses the Dinaric Alps, a mountain range rich in biodiversity. The fauna of Orthoptera has, in recent years, been an important subject of study in Croatia, but many of the Dinaric mountains in Croatia remain poorly sampled. Bosnia and Herzegovina, with the exception of some foreign expeditions, remains almost completely unknown with regards to the distribution of Orthoptera.
