Insect diversity and new records from mangrove forests of Cat Ba National Park, Vietnam, using multi-method sampling

A groundbreaking survey of insect diversity in the mangrove forests of Cat Ba National Park, Vietnam, reveals 163 species across 11 orders, with eight new to science and four newly recorded for Vietnam. Hemiptera dominated the findings (37 species), followed by Lepidoptera and Diptera, underscoring mangroves as critical biodiversity hotspots. Multi-method sampling—sweep nets, light traps, and yellow pan traps—identified sweep nets as most effective, particularly for Hemiptera and Hymenoptera, while light traps excelled at capturing Lepidoptera. This study provides the first comprehensive baseline for insect diversity in Cat Ba's mangroves, offering insights applicable to understudied Southeast Asian ecosystems.
