Here's how I see this.
Since flies weigh 0.5kg, they need to put force of 5N, to stay in midair (F=m*a, where 'a' is the opposite of gravity, so 5N=0.5kg*10m/s2 (gravity simplified)).
Pic rel. Force that keeps the flies from falling (5N) goes into the air, below them. (F1)
Part of the force gets absorbed by the bottom of the jar, adding weigh to it. (F2)
The rest is reflected up, making it so that the air in the jar is in circulation. (F3 and second drawing).
That would make the total weight of 1kg + F2/(10m/s2), so something between 1kg and 1.5kg.
