The western U.S. is home to two known native species of subterranean termites, Reticulitermes hesperus (shown here) and Reticulitermes tibialis. But a new analysis shows R. hesperus is likely a species complex of at least two distinct species, and at least five species Reticulitermes in all may be present in California. A better understanding of these separate subterranean termite species and their behaviors will be essential for effective management. (Photo by James Bailey via iNaturalist, CC BY-NC 4.0)
