The greater ghost bat is a large, pale bat with few known field records from northern South America. Detailed information about its life is limited.
Diclidurus bats are whitish to pale gray-white. This species is described as larger than its close relative D. albus.
Very little is known about its biology. In Venezuela, specimens were reported in flight over stream banks and other moist places, in yards, and in evergreen forest.
