This study investigated differences in the predation rate of lepidopteran larvae across El Niño phases within an urban-agricultural landscape in Southcentral Mindanao, the Philippines. Predation rates were considerably higher in the pre-El Niño phase (mean 18.24%) than during the peak of the El Niño phase (mean 6.41%) and showed a slight, yet statistically insignificant, rise in the post-El Niño phase (mean 9.48%). Although predation by arthropods on herbivorous preys remained predominant during all periods, vertebrate predation was related to the warmer and drier conditions of El Niño associated with the 2023 ENSO.
