Ants Adopt A CATERPILLAR!

What the if you got zapped by a shrink ray while walking past the physics department and your only hope of survival was convincing a colony of ants to take you in? Lycaenid butterfly caterpillars have been pulling this con for millions of years, hacking ant colonies with fake chemical IDs and rhythmic vibrational passwords to sneak past the bouncers. Once inside, some get the royal treatment in ant kindergarten while others take a much darker approach to fitting in that you really need to hear to believe.

Based on "The Password That Lets Caterpillars Hide in an Ant's Lair" by Rebecca Zambach, published in The New York Times.
