These things are weak to whips since it knocks them out of the air. So you could swap into a melee weapon and kill it once it fell on the ground, the accuracy is around 40% - 60%

If the map does not have scorched earth engrams. Then run away, this will force it to get close to the ground along with making it go in a straight line. This should really help with fighting this pest. So run a little then fight.
