RECOGNITION
Diversity
Three species in North America. Two species in California: Z. angusticollis (Pacific Coast Dampwood Termite) and Z. nevadensis (Nevada Dampwood Termite).

BIOLOGY
Habitat
Generally found in the rotting wood of trees, both living and dead. More common in the dead wood of fallen trees. These termites will also infest damp wood in structures.
Importance
These termites will infest damp wood in structures.
Range
Wesern North America, Canada south to northern Mexico.
Diversity
Three species in North America. Two species in California: Z. angusticollis (Pacific Coast Dampwood Termite) and Z. nevadensis (Nevada Dampwood Termite).
Importance
These termites will infest damp wood in structures.
Development
Colonies are founded by a primary reproductive king and queen. Thousands of primary reproductives fly at one time (swarm) and mates pair off. Reproductives remove their wings and excavate a small chamber. The chamber is typically under the bark of a dead tree previously entered by beetles, but these termites will also use other damp or waterlogged wood. The first eggs to hatch develop into soldiers. Subsequent hatches become workers. Unique to this Bay Area genus, Zootermopsis workers may change castes to become soldiers or primary reproductives. Additionally, the Zootermopsis have a fifth caste of fertile workers called "secondary reproductives" or neotenics which are darker and have wingbuds. There may even be a sixth caste of reproductive soldiers which have wingbuds and modified mandibles and abdomen. As the wood source in which the colonies are growing is depleted, more of the workers develop into winged reproductives. Dampwood Termite colonies do not move from one wood source to another. Colonies die out once the wood source has been fully consumed.
