Summary
Leptoglossus occidentalis Heidemann, 1910 is an invasive bug species native to the western part of North America and one of 16 alien Heteroptera species in Europe. After it was first found in Italy in 1999, the species spread fast across the continent, including the Balkan Peninsula. Our study confirms the species presence in Bosnia and Herzegovina and gives data on its distribution, including the earliest records for the country. Up untill now the species is found at nine different locations in the period from 2008 to 2016. The record from early spring 2008 suggests that the species was already present in Bosnia and Herzegovina in 2007 or even earlier. Most records pertain to overwintering adults. For the first time the species is reported from Bosnian pine (Pinus heldreichii H. Christ). The species is also reported from Klek village in Dubrovnik region, south Croatia.

INTRODUCTION
Uvod
True bugs (Heteroptera) are one of the most diverse groups of insects with approximately 40.000 described species (Schuh and Slater 1995), out of which about 3.000 occur in Europe (Aukema and Rieger 1995–2006). Protić and Stanković (2015) estimated that the number of Heteroptera species currently known to occur in Bosnia and Herzegovina is roughly 750.
