Record of Lepidoptera and Hemiptera as a food resource of Acutisoma longipes Roewer, 1913 (Arachnida; Opiliones) in the Cerrado, Brazil

Abstract

Harvestmen are nocturnal arachnids, commonly found in humid forests, with omnivorous feeding behavior. There are records of different taxa in the diet of these arthropods, but data is still scarce for many species, especially in Cerrado areas. Thus, the objective of the present work is to report Lepidoptera and Hemiptera in the diet of the harvestman Acutisoma longipes Roewer, 1913, in Mata de Galeria in the Cerrado of Minas Gerais, Brazil. The records occurred randomly in the municipality of Luminárias, Minas Gerais, on October 10th and December 4th, 2023. In the first record, the species A. longipes was feeding on a moth (Lepidoptera: Erebidae). In the second record, the same species fed on a leafhopper, Mahanarva sp. (Hemiptera, Cercopidae). It was not possible to say whether these insects were preyed upon, usurped by other predators or found dead, but any of these hypotheses can be considered. This record contributes to increasing knowledge about the diet of harvestmen, especially in the Cerrado biome, where there is a need for more related studies.
