Mine doesn't seem overly phased by tweezer feeding, but in saying that I have only done it once or twice and prefer him chasing them around the enclosure...
He is fed in his enclosure and is generally sitting on the basking spot when I put them in, he seems to follow their scent around and sort of goes on a patrol looking for them, but when he finds them he just sort of stares at them until they walk off...
(By the way, I just discovered he will eat those spiders that curl the leaves in the middle of their web too..
)
