I suppose that depends on the rate of success. Admittedly, no modern
animal that I know of catches insects by leaping from the ground into
the air, or by snatching them mid-air while parachuting or gliding.
The birds and bats that do this are powered fliers and have excellent
maneuverability.
I have seen a bird do this. Granted, it was a faster flier, but in this
instance, it simply leaped up to grab a passing horsefly and dropped
back down to the ground. I'm not sure which species of bird it was, but
if there are any bird specialists here - I'm in Dartmouth, Nova scotia,
Canada and the bird was under pigeon size, prolly six to seven inches
long, black, with an orange/brownish beak, and the it's plumage may
have had a hint of brown on the edges of it's feathers.
