ELI5: Why do small animals run away from me even though I'm no threat but bugs constantly land on me and I frequently kill them?

Every time I see a small lizard or chipmunk they seem terrified and run from me, even though I pose no threat, but whenever bugs land on me I either swat them or crush them and they just keep on coming at me. And  I am not talking mosquitoes either I'm talking like small flies and moths and such.

They don't know that you pose a threat and they have no need to take the risk. Bugs, can bite and some need to feed on you. The flies can fly quite fast and your movements are too slow for them. So, they can safely take the chance. The moths usually land on when you stay still.
