Discothyrea

Sign in to save

Discothyrea is a genus of small ants in the subfamily Proceratiinae. The genus is distributed in the tropics and subtropics throughout the world, where they usually nest in rotten wood, in the leaf litter, or under stones. Little is known about their biology, but ants in this genus are thought to be specialist predators of arthropod eggs and have been observed storing eggs in their nests (probably spider eggs).

Discothyrea is a genus of small ants in the subfamily Proceratiinae. The genus is distributed in the tropics and subtropics throughout the world, where they usually nest in rotten wood, in the leaf litter, or under stones. Little is known about their biology, but ants in this genus are thought to be specialist predators of arthropod eggs and have been observed storing eggs in their nests (probably spider eggs).

Two fossil species, D. gigas and D. maya, are known from Dominican and Mexican amber.
