- <p><em><span lang="EN-US">Graphosoma italicum italicum</span></em><span lang="EN-US"> (Hemiptera: Pentatomidae) is a phytophagous true bug widely distributed across the Western Palearctic and frequently associated with Apiaceae plants. In Armenia, its ecological relationships remain understudied despite increasing availability of biodiversity records. This study investigates the spatial co-occurrence between <em>G. italicum italicum</em> and selected Apiaceae genera (<em>Anthriscus</em>, <em>Heracleum</em>, <em>Daucus</em>, <em>Prangos</em>, <em>Falcaria</em>) across Armenia, using a combined dataset of field surveys (2023–2025) and open-access records. Data was processed through a uniform 3.5 × 3.5 km spatial grid, and species overlap was quantified using the Jaccard Similarity Index. A total of 50 insect records and over 100 plant observations were analyzed. The highest co-occurrence was found with <em>Anthriscus</em> (J = 0.2), followed by <em>Heracleum</em> (J = 0.1), while <em>Falcaria</em> showed the weakest spatial association (J = 0.07). Results indicate moderate but ecologically meaningful spatial overlap, suggesting potential host preference or shared habitat affinity. This study provides a foundation for future research on plant–insect interactions and spatial ecology in the South Caucasus.</span></p>
