The brown marmorated stink bug, Halyomorpha halys (Stål, 1855) is an invasive, highly polyphagous species, native to Southeast Asia. Adults and larvae of H. halys feed on various plant species, including field crops, vegetables, fruit trees, and ornamentals. In the fall of 2018, the species were observed in Bosnia and Herzegovina for the first time, in the city of Mostar. A single specimen was caught inside the family house in the center of Mostar. A few weeks, two more adults were found in municipality of Čitluk. On December 2018, one adult species were caught on Bosnia and Herzegovina-Croatia border crossing near town Bosanski Šamac. Species identification was carried out at the Faculty of Agriculture and Food Technology University of Mostar. Identification was done by morphological characteristics of adults. The current distribution, morphology and biology of the species, harmfulness and control measures are briefly reviewed in this paper.
