Abstract

This study aimed to investigate the diversity of ants captured in Myrmeleon pits in a Cerrado environment (Brazilian savanna) and assess the relationship between pit size and capture success. Field expeditions were performed in the Inhamum Municipal Environmental Protection Area, Caxias, Maranhão State, Brazil. Pits of Myrmeleon larvae were observed, and captured ants were collected and identified. Our results showed that Myrmeleon larvae inhabiting this Cerrado site rely on ants as their main natural prey. Seven ant species were identified. There was a positive relationship between pit diameter and capture success. This is the first investigation of the diversity of ants naturally predated by antlions.
