Extremely abundant thruout the basin. The commonest species of 

 Cyrtolobus in the region. Found on almost all varieties of oaks and 

 occasionally on chestnut. The entire life history is passed on one host. 

 The eggs are laid in the late fall, and winter over, and two broods a year 

 appear in some seasons. The nymphs are plentiful and easily distin- 

 guished. The species is recognized by its small size and very characteristic 

 markings.
