Morphology
The meaning is directly compositional: 'chalcid' (a wasp-like insect) modifying 'fly' yields a specific kind of small insect, so the overall sense as a particular insect type is derivable from the parts. While 'chalcid' is somewhat technical, assuming the learner knows that constituent, the compound denotes a type of fly and is immediately interpretable.
Etymology
Chalcid fly may come from an old Greek word for 'copper', because many chalcid insects look shiny like metal. These small, wasp-like flies have young that grow inside other insects' eggs, so the name now refers to tiny helpers that 'control pests'.
