Crematogaster abstinens occurs in wet or dry forest habitats, but is more common in the latter. I have never collected this species myself and have no first-hand knowledge of its biology. It has been taking by sweeping on Barro Colorado Island, and by sweeping at night in Brazil (Mato Grosso). Ward collected ground foragers in Bolivia.
