In the spring and early summer a number of buds and small nuts may be
covered with foamy white masses. Inside these masses are several small
insects called spittlebugs, _Clastoptera obtusa_ (Say). The white froth
is produced probably to maintain an artificial high humidity, which is
required for development. The adults resemble leafhoppers and fly
actively during the summer.
This insect has not been known to cause any significant injury on pecans
in Texas.
