Collecting information

Specimens can be found in pastures of Urochloa brizantha and Urochloa decumbens and in areas of native Cerrado. Specimens are attracted to cattle dung, light and can be captured by flight intercept. The species can be found at altitudes up to 1600 m (Dellacasa et al. 2011; Mesquita et al. 2017).
