Penelitian tentang kelimpahan kumbang daun (Coleoptera: Chrysomelidae) di Stasiun Penelitian Suaq Balimbing bertujuan untuk mengidentifikasi dan menganalisis kelimpahan kumbang daun di SP Suaq Balimbing. Metode yang digunakan adalah metode jelajah (explorative) dan observasi langsung pada objek pengamatan (direct explorative) mengikuti jalur trail sepanjang 1000–1500 meter dengan lebar lima meter. Sebanyak 260 individu, 30 genus, dan 45 spesies kumbang daun ditemukan dan dikelompokkan ke dalam empat subfamili. Galerucinae adalah subfamili yang paling melimpah dengan 201 individu, yang mewakili 77,3% dari total kelimpahan di area penelitian, diikuti pada Eumolpinae (10,4%), Cassidinae (9,6%), dan terakhir Criocerinae (2,7%). Kelimpahan spesies tertinggi diwakili oleh Acrocrypta aureipennis (16,54%) dan Pseudosastra sucicollis (15%). Data kelimpahan kumbang daun di SP Suaq Balimbing menjadi data dasar untuk pemantauan ekologis dan konservasi di kawasan tersebut.

Research on leaf beetle (Coleoptera: Chrysomelidae) abudance 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. We documented 260 individuals representing 30 genera and 45 species, classified into four subfamilies. Galerucinae was the most abundant subfamily with 201 individuals, accounting 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 were represented by Acrocrypta aureipennis (16.54%) and Pseudosastra sucicollis (15%). These leaf beetle abundance data provide baseline information for ecological monitoring and conservation in the area. Keywords: leaf beetle, chrysomelidae, abundance, Suaq Balimbing Research Station
