All submissions to Entomologia Croatica are first reviewed for completeness and only then sent to be assessed by an Editor who will decide whether they are suitable for peer review. Where an Editor is on the author list or has any other competing interest regarding a specific manuscript, another member of the Editorial Board will be assigned to oversee peer review. Editors will consider the peer-reviewed reports when making a decision, but are not bound by the opinions or recommendations therein. A concern raised by a single peer reviewer or the Editor themself may result in the manuscript being rejected. Authors receive peer review reports with the editorial decision on their manuscript.

Proceedings papers are reviewed by the Programme Chairs and Programme Committee members of the respective conference, with help from external reviewers selected by them.
