Pine tree ants, Liometopum luctuosum, are common in the 2000-4000 foot elevation range in Tuolumne and Calaveras counties. This is … Trash piles, called middens, accumulate in underground chambers during weather that inhibits above-ground activity, and are then moved to the surface after spring and summer rains when ants rebuild galleries and clean house.
