Morphology
The noun phrase is compositionally built from 'black' (color) + 'fly' (insect), so a B1 learner who knows both words will readily infer it denotes a dark-colored fly. The specialized entomological details (family Simuliidae, biting habit) are additional encyclopedic information but do not prevent the basic meaning being transparently derived from the constituents.
Etymology
Black fly comes from the insect's look: the word black means dark and the word fly means a small flying insect. These tiny dark flies often bite and make people itchy, so the name now means 'a small dark biting fly'.
