Abstract. We describe the extraordinary nesting habits of
the fungus-growing ant Cyphomyrmex cornutus (Formi-
cidae, Myrmicinae, Attini) and the natural history of
Megalomyrmex mondabora (Formicidae, Myrmicinae,
Solenopsidini), a social parasite that inhabits nests of C.
cornutus and other small attine ants. The study was
carried out at two sites on the Atlantic slope of Costa
Rica. The C. cornutus nest is an oblong mass of accreted
soil, attached to or suspended from low vegetation in wet
