Orius Wolff 1811 occurs throughout Oriental, Ethiopian, Palaearctic, and Neotropical regions and feed on a wide range of insect pests. This study investigated habitat suitability for 15 species of Orius under current and future climates throughout Iran using a Maxent modeling approach, combining presence-only field data with climate derived variables. To produce the models, samples were collected from 310 localities where the Orius was found. The accuracy and performance of distribution models were also evaluated by the area under receiver operating characteristic curve and jackknife analysis. In the Maxent model, the climatic and elevation were the major bases for the current models. In modeling future distribution, the elevation was excluded. Precipitation of the wettest period was significantly important within the model. The potential distribution of the Orius species under variable climates exceeded the current distribution in some areas of Iran, notably the northwestern and northeastern regions. Under future scenarios, the climatically suitable areas for Orius species globally were projected to expand.
