They have the termites and ants convinced they are one of them, thusly, they are fed and cared for…clever. The termites and ants never know they are feeding and caring for a beetle.
Or do they?
The tiny beetles are everywhere, but most interestingly, in ant and termite colonies, where they evolved to live as social parasites, mimicking the ants in body shape and producing chemicals that in some cases even convince the ants to feed them. In other cases they prey on ant young and steal food, all the while masquerading as colony members.
