Morphology

monophagous = phagous (transparent) = mono + phag + ous

The adjective is directly built from the base 'phagous' by adding the prefix 'mono-', yielding the literal sense of 'feeding on one kind'.

Etymology

Monophagous comes from Greek parts mono- 'one' (as in monopoly) and phagein 'to eat'. So a monophagous animal eats only one kind of food, which is why it is at risk if that food disappears.
