The ecology of this species is unknown, but it is suspected that it is the same as or similar to
Oedoparena glauca where
Eggs are deposited on the
operculum of barnacle and fly
larvae consume several barnacles during their development. Pupation then takes place in a now empty barnacle shell. The adult flies emerge during the morning low tide. Adults of
Oedoparena glauca, and
Oedoparena nigrifrons are found together in the same habit. ==References==
