Morphology
The phrase is compositional: 'trematode' names a specific kind of parasitic flatworm and 'worm' gives the general biological category, so the combined noun simply denotes a worm of that type. A B1 learner who already knows the meanings of both constituents can therefore infer the MWE's meaning without special idiomatic knowledge.
Etymology
Trematode worm names a flat worm with round, sucker-like mouths that attach to an animal or person and feed on them. Because these worms cling to a 'host' and live on it, the term refers to this kind of 'parasite'.
