It rains under the Tipu trees (Tipuana tipu)

When November comes and rosewoods become green again an unusual phenomenon is witnessed for only a couple of weeks - it rains under the rosewoods no matter if it is a sunny or cloudy day.This is caused by an insect, the spittlebug, whose nymph feeds on this tree's sap. The nymph produces a spittle mass around the stalks which is a good cover against predators and keeps it moist. The foam is the waste product eliminated after sap nutrients have been absorbed, into which air bubbles are introduced through a breathing tube which is at the end of the abdomen of the nymph.
