In February 2012 Jorge found an interesting hawkmoth by the kitchen that was later identified as a female Enyo cavifer. Although this species has a wide range in the Neotropics, it is a rare species in Brazil and the last record for the Serra dos Orgaos was collected by Henry Pearson in 1967.

This latest record is not only a first for REGUA, but a first for the municipality of Cachoeiras de Macacu. This takes the number of hawkmoth species recorded at REGUA to 69 out of the 110 known to occur in the region.
