[Men in Black] Why did The Bug bother trying to negotiate with Edgar?

The first thing The Bug says is "Place projectile weapon on the ground." Did a shotgun pose any threat to it? Would it have immediately grabbed and eaten Edgar anyway if he had complied? It didn't seem to have any trouble ambushing him, and was openly bigoted towards human life, so why ask him to surrender?

You can see through the rest of the movie that the Bug has a rather Sarcastic or Cynical Personality, so maybe this introduction was only to show his traits for the rest of the movie.

Second thought: It was an easier way of luring Edgar closer to the hole, if you are a being that feels superior you might think that ambushing or attacking first it's a waste of energy... Reason why the Bug basically only killed when it felt fully offended (when a person kills cockroaches) and didn't kill Edgar's wife (he may have thought it was a waste of time)
