It's interesting and sophisticated behaviour, but there are limits to what extent I'd characterise it as intelligent. I'm sure the spider has no concept of the animals it's mimicking, or that it's even mimicking an animal, or anything else. It might even be a stretch to describe their tactics as 'planned' in the human sense, as they're probably automatic responses to stimuli. They're still one of the most interesting and adept creatures we commonly encounter though.
