The head is darker yellow and mandibles brown. The soldier ants have large brown heads, comprising at least one-third of their entire bodies. The queen ant is much larger than the other forms, while the males are small. It is claimed that there are no less than 15 kinds of in- dividuals in this species. Life History These termites usually live in dead or decaying wood but often work into the living and growing tissues. They make very extensive galleries through all parts and thus often ' destroy buildings, fences, etc., as well as fruit trees. The queen gives rise to all the young, which appear in great numbers, especially dur- ing the summer months. In the fall or autumn winged or migratory forms ap- pear and often fly by thousands on dark days and towards evening. In habits and life history they greatly resemble true ants and bees. General. Distribution Food Plants As previously stated, these termites usually work upon dead or decaying wood, but then usually only in the pres- ence of moisture. These insects often be- come destructive to fruit trees, working upon the roots underground and making galleries up the trunk. No doubt they usually begin to work in the decaying tissues but often continue into the healthy portions of the tree. Nectarines, peaches and apricots seem to suffer most, while citrus and other trees and plants are also attacked. Control ^ Due to their secluded work the damage is usually done before their presence is known and too late to effect a remedy. However, if close observations are made in infested districts and their work dis- covered the colony may be almost entirely exterminated
