Defoliation caused by larvae of the brown-tail moth (Euproctis chrysorrhoea) poses a significant threat to oak-dominated ecosystems in Armenia, particularly under the influence of escalating climatic stressors. This study investigates the species’ feeding behavior, defoliation dynamics, and phenological shifts on degraded oak stands by integrating systematic field monitoring with historical climate data. A key finding of the research is the delayed emergence of adult moths (imagines), which appears to be strongly correlated with area's dryness.
