Formicidae -- Ant Family

A rough harvester ant colony is founded by a sole founding queen and the only active reproductive. The queen continues to lay eggs as long as the colony survives over a period that may last longer than a decade. During this time a grand collection of seed hulls will accumulate in areas beyond the nest entrance. This natural mulch can become a wonderful seed bed once the queen has died and the colony collapses.
