The reproductive and feeding ecology of Anops kingii was studied at the pampas mountain range of Argentina. Reproduction occurred from late winter (July) to early summer (December).

Diet was not diverse and consisted mainly of coleopteran larvae. Foraging activity decreased during the coldest months of the year. Individuals were found under large rocks predominantly during winter and spring.
