2) they want deceive predators pretending to be ants.
In this case it is ridiculous to assume that spiders are mimicking ants only when their predators do not observe them.

I suspect you're being intentionally obtuse here.

The spiders mimic ants, which keeps most insectivore predators away.

Any predator that shows interest is likely to be one that prefers ants.

When a predator does show interest, the spider tries to look more like spider.  Since the predator prefers ants, it loses interest in the spider.
