The way some bugs walk, specially flying ones

I was watching a wasp walk over a window (luckily from the other side) and just noticed how unnerving they are when they move that way. It's like watching a movie made using rotoscoping while everything around moves normally. Same thing with flies for example, when they fly they look normal but walking it's as if they were skipping frames. And when they rub their legs or antennas, it's so creepy.

I find bugs cool as much as the next person, but seeing them move from up close like that makes me nervous.
