Morphology
water + boatman
A B1 learner who knows 'water' and 'boatman' will most likely interpret the compound as a person associated with boats or water rather than a specific insect; the constituent meanings do not transparently yield 'small aquatic insect'. 'Water boatman' is a conventional taxonomic/common name where 'boatman' is metaphorical for the insect's rowing-like legs, so the overall meaning is not predictable from the parts.
Etymology
Water boatman gets its name from the way the insect swims: its flat back legs paddle like oars, so it looks like a tiny boatman on the water. That's why the name refers to a 'small swimming insect'.
