This is a gizzard worm of aquatic fowl, most commonly of geese and ducks, found throughout the world. It is a member of the [[:Category:Trichostrongyloidea|Trichostrongyloid family]] and has a life cycle typical of this family ([[Trichostrongyloidea - Overview|Trichostrongyloid life cycle]]). These worms and larvae are found beneath the lining of the gizzard.

This species is similar to ''A. anseris'' above in appearance. The major host for this nematode are both domestic and wild duck species and it can be found worldwide. The main defining feature of this species is the requirement for hatched L3 larvae to exist for about 5 days in the environment before being fully infectious.
