This study aims to perform an ecological and zoogeographical analysis of the Meloidae in Ankara province, Türkiye. The ecological evaluations detected higher species diversities in June, 701-900m in elevation range, and 20.1-25.0°C in air temperature. There was no difference in the detecting elevations according to the phylogenetic positions of the species, a significant difference was observed between the collecting air temperatures. Host plants of 33 species were identified. The zoogeographic analysis revealed that the highest rate (18.6% of the detected species) was in the Turano-European regions. Table 5.
