Moggridgea terricola is a terrestrial burrowing trapdoor species. Burrows were found singly on bare flats under the shade of trees and bushes. They also construct burrows in mossy banks.
The species was originally described by Eugène Simon in 1903 from Stellenbosch. Charles E. Griswold's 1987 revision synonymized Poecilomigas ''affinis'' with this species.
