Well...going back to D&D a moment, "fine" creatures (i.e. the smallest category reserved for things like flies and ants) are immune to physical weapon damage.
Yes, IRL if you manage to hit a fly with a balista bolt it's dead. Unfortunately IRL there's this funny thing called "air pressure" which pushes things around. Large, flying balista bolts generate enough air pressure currents to knock aside tiny things--like flies.
Heck, most hand-held weapons cause enough air movement to either push aside the fly, or give it reaction time to just move out of the way. This is why flyswatters have holes in them: to reduce that air pressure (and doesn't do a good enough job, but it's better than a rolled up newspaper or warhammer).
As for slashing and piercing weapons of all kinds...well...how far in how long does the fly have to move (at random) to not get hit? Uh...half it's body size in 1/10th of a second. Or roughly 1 inch in 1 second or 6.25 feet in a minute. 375 feet an hour. That's really really slow.
Some googling indicates that insects typically measure speeds in the double-digit miles per hour (slowest speed noted so far is 2.5 mph of the mosquito).
It'd be like a car on the highway dodging a bullet. No no, lets be realistic about this. A car on the freeway--the only car on the freeway--dodging a guy throwing rocks from a block away: he can probably get rocks to the freeway, and he might be able to time it to hit the car, but if the dude knows the rock-tosser is there he can stop or speed up just a little and make that guy miss.
