On a still-sweltering evening in Tanzania more than a decade ago,
my colleagues and I crouched around a fresh pile of elephant dung to witness an
epic struggle of wills. Immediately upon our arrival, beetles began plunking
into the grass around us. Soon dozens were raining down from the sky at once,
and, not being the most agile fliers, they tumbled into our hair and bounced
down the backs of our necks. Within a few short minutes, as many as 50,000 dung
beetles landed, all racing to carve out a meal for themselves and their young.
