Seasonal analysis of Saturniidae (Insecta: Lepidoptera: Bombycoidea) in a remaining Atlantic Forest in the State of Espírito Santo, Brazil

Abstract

The Lepidoptera family Saturniidae is commonly utilized as a bioindicator for ecosystem monitoring. During six years of sampling, the study explored the dynamics of the Shannon-Wiener, Simpson, species richness, Pielou equity, dominance, and abundance ecological parameters under the effect of seasonality. The research took place in the Atlantic Forest remnants at Vale Natural Reserve in Linhares, Espirito Santo, Brazil. Blacklight traps were used to collect the samples. 1,445 specimens were collected and classified into four subfamilies, 30 genera, and 48 species. There is a large difference in richness and abundance due to temperature in different seasons. When the temperature drops, the abundance declines. When comparing years, equitability and dominance are not significant. During periods of more rainfall, there is a higher abundance of species (richness). Despite variations in abundance and diversity throughout the years, the Saturniidae are known for their low resistance and strong resilience.
