ok tidying up loose ends as I had an idea. I went with 3d4 hp - also a spit attack maybe?
Tweaking it up to 7 hit points is OK by me. If seven hp is good enough for a Pseudodragon it's good enough for a Venomwing!
I'd caution against a Spit attack as that allows it to fly out of melee range and snipe, allowing it to (a) exploit PCs with weak ranged attacks, and (b) focus fire on single targets (e.g. a dozen venomwings would have trouble all biting a single opponent, but it'd be trivial for them to all spit at one.
For a similar reason I'm thinking we should remove the Flyby ability as it also makes it very hard for melee focused creatures to fight them. A Pseudodragon doesn't have that ability, allowing its enemies to at least use their Reaction to make an attack as it zips past them.
That'd increase its Challenge to 1/2 and I'd rather keep it at 1/4.
Also, Spit make it harder to stat up a swarm of these critters. How would they use their Spits? Could some of them spit while others bite. Do they divide their spits among targets, all spit together in a cone of expectorate, or what?
