The first step off the minivan is into an evening that feels alive — a humid breath, a chorus of insects, and the forest gradually unwinding from day into a low, watchful dark. Within minutes the understory begins to blink: small golden pulses that swell into dense constellations around the trail. In Totláli, those pulses are not random; they are a choreographed courtship, thousands of beetles signaling across trunks and low branches.
