i presume, the hairy structures, on the wings were to catch the lightest of breezes

Actually no - they're to minimize noise so it can fly silently. Owls have similar fringing on their feathers for the same reason. For an insect I would imagine they also help break up the visual edges to protect from predators. Fringing is energy-expensive, so most birds and insects rely on speed and ability instead. But fringing can't be beat for stealth and silence.
