There's a fly in my oil!

I was pouring some oil from the big 5-quart jug into a 1-quart jug when a housefly got too close and fell into the 1-quart jug.
Is this what the oil filter is for?
Or should I fish him out of there?
I was leaning towards letting the oil filter do its job, but would little bits of fried fly plug up the oil galleries in there...?
