Why the ants in this video kept crawling around an iPhone

The video’s description on YouTube claims the insects acted that way, because they were affected by the “electromagnetic wave of an incoming call.” University of New England associate professor Nigel Andrew agrees: “[They] have magnetic receptors in their antennae. If they’re travelling long distances they use magnetic cues from the earth to know if they are going north, east, south or west.”

Freaky.
