Population dynamics studies make it possible to predict the response of species to seasonal and inter-annualclimatic phenomena in hypothetical scenarios of climatic abnormality. However, long-term studies on the tem-poral distribution and abundances of species are still scarce in the literature, including for species of agriculturalimportance. The present study aimed to bridge this gap through monthly collection events of species of cut-worms (species ofAgrotisandFeltia) across eight crop seasons (from July 2012 to June 2020) in the BrazilianSavanna (Cerrado). This biome is characterised by an irregular distribution of rainfall during a normal year, in-cluding two well-defined periods of dry and rainy seasons. Onlyfive species of cutworms were recorded:Agrotis ipsilon,Agrotis canities,Feltia repleta,Feltia submontanaandFeltia subterranea, all widely distrib-uted across South America. Except forF. submontana, occurring only in the autumn, other species occurrednearly year-round, with distinct peaks of abundance in the dry season (April to October), supporting thehypothesis that species of Agrotina are well adapted to dry environments. The association of cutworms withdry environments was recovered for multivoltine, abundant species, such asA. ipsilonandF. subterranea,asfor univoltine species, such asF. submontana. Across eight crop seasons, the abundance of all speciesdecreased, coinciding with a high intensity El Niño effect. However, the effect itself was not found to besignificant to predict the temporal distribution and abundances of cutworms and the causes of population de-crease from 2014 to 2015 crop season remain to be explained. After the temporal autocorrelation effects wereremoved, it was revealed that the abundance of cutworms tends to be larger in crop seasons with less precip-itation. Thus, this variable can be used to predict outbreaks of cutworms in the Cerrado. Some species of cut-worms deserve special concern due to their frequency, seasonality and higher abundances in the Cerrado duringthe dry season. Their adaptability to adverse conditions may increase their spatio-temporal distribution in Braziland the frequency of outbreaks in a scenario of climate change, with the continuing reduction of rainfall incentral and southeastern Brazil.
