It's still missing the original's
summon swarm ability.
How's this:
Insect Summoning (Sp): Once per day a demonic sawfly can summon a swarm of gnats and flies. This functions like a
summon swarm spell (CL X) except it summons a gnat swarm with the following statistics:
Gnat Swarm
Fine Vermin (Swarm)

Feats: —
Challenge Rating: 2
Alignment: Always neutral
Distraction (Ex): Any living creature that begins its turn with a swarm in its space must succeed on a DC 11 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.
Wounding (Ex): Any living creature damaged by a gnat swarm continues to bleed, losing 1 hit point per round thereafter. Multiple wounds do not result in cumulative bleeding loss. The bleeding can be stopped by a DC 10 Heal check or the application of a cure spell or some other healing magic.
Skills: A gnat swarm has a +4 racial bonus on Listen and Spot checks.
Not sure about the Gnat Swarm. Its AC seems rather high. Maybe we'd be getter off making them "giant" gnats (Diminutive Vermin) and maybe lowering the Dex by 2 or 4, giving them Armour Class 18 to 16.
A high Dex and AC does seem appropriate for flies though, and it saves us having to rewrite masquerade to allow for a swarm of non-Fine sized insects. Although we might as well consider the possibility:
Masquerade (Ex): When a demonic sawfly assumes Diminutive or Fine size, it appears to be a verminous insect unless the viewer succeeds on a Spot check opposed by the sawfly's Disguise check. The demonic sawfly gains a +12 circumstance bonus on Disguise checks to masquerade if it is within a swarm of vermin.
Speaking of which, the original monster could
only shrink to the size of an ordinary insect, suggesting the Change Size should be:
Change Size (Su): As a standard action, a demonic sawfly can magically shrink to the size of an ordinary insect. This functions like a reduce person spell, except that the ability can work on the demonic sawfly and it reduces its size to Fine. A demonic sawfly can return to normal size as a swift action.
Alternatively, we could make the Swarm distraction only, but IIRC the AD&D
insect swarm spell inflicted damage.
