In November 2023, an adult of M. polyglottos was captured using mist nets. The capture habitat consisted of secondary vegetation comprising shrubs and natural grassland. Despite the area of the record being in the process of regeneration and being surrounded by agricultural plots, the presence of M. polyglottos may be associated with the availability of key resources, such as small insects and fruits of native plants. Areas under habitat restoration play a crucial role in the conservation of biodiversity and species survival.
