Specimen labels note collections from Victoria Desert, Casuarina, and clay soils of a minesite. These vague, eclectic notes are all that is known about the biology of Monomorium megalops.
Heterick (2001) - A member of the monomorium group. Apart from the shape and size of its eye, M. megalops is virtually identical with Monomorium sordidum, and may eventually prove to be no more than a variant of that widespread species.
Heterick (2009) - Monomorium megalops is identical to Monomorium sordidum, apart from its large, reniform eye.

Heterick (2009) - The distribution of this species centres mainly on inland NSW and SA, but there is one record in the SWBP from Westonia, WA in the western goldfields.
