Study on leaf beetle (Coleoptera: Chrysomelidae) abundance at Suaq Balimbing Research Station aimed to identify and analyze species abundance patterns. Specimens were collected through exploratory surveys with direct observation along trail transects measuring 1000-1500 meters in length and five meters in width. A total of 260 individuals belonging to 30 genera and 45 species within four subfamilies were identified. The community was strongly dominated by Galerucinae (77.3%), while Eumolpinae, Cassidinae, and Criocerinae were comparatively less represented, contributing 10.4%, 9.6%, and 2.7% of the overall abundance. We documented 260 individuals representing 30 genera and 45 species, classified into four subfamilies. Galerucinae was the most abundant subfamily with 201 individuals, accounting for 77.3% of total abundance in the study area, followed by Eumolpinae (10.4%), Cassidinae (9.6%), and finally Criocerinae (2.7%). The highest species abundance was represented by Acrocrypta aureipennis (16.54%) and Pseudosastra sulcicollis (15%). These leaf beetle abundance data provide baseline information for ecological monitoring and conservation in the area. © 2025, Penerbit Universiti Kebangsaan Malaysia. All rights reserved.
