(Bartr.) Small, and one or more species of scrub oak, Quercus spp., 
typical of sand pine forest. O. vicarius nymphs were found beneath 
the numerous logs and stumps in mature stands of sand pine and oak. 
Records were made of nymphal chamber construction, log dimen¬ 
sions, and state of decay. 
Late-instar nymphs were brought to the laboratory for rearing. O. 
vicarius nymphs, along with the rotten wood and wax fibers of their 
original chambers, were placed on moist cotton in Wilson cells. The 
ambient temperature was held at ca. 21° C. A mass of eggs was kept in 
a tightly sealed shell vial with material from beneath the logs. 
O. vicarius adults were recorded for the years 1969-76 from a 
blacklight trap located adjacent to turkey oak and pine woods at the 
Division of Plant Industry, Doyle Conner Building, Gainesville, 
Florida. 
Results and Discussion 
When oak and pine stumps and logs were overturned, masses of 
wax fibers invariably indicated an O. vicarius chamber. The white, 
opaque, fluffly lining of the chambers consisted of numerous wax 
fibers (1-3 mm long) produced from wax plates on the abdomen of 
the nymphs (Mead 1968). When nymphs were disturbed, they 
appeared to drop their wax fiber “tails” or to knock them off while 
escaping. 
Nymphs were found beneath logs and stumps ranging from dry 
and relatively decay-free to almost fully decayed and easily pulled 
apart; all were partially buried in the duff of the forest floor. Nymphal 
collection data are presented in Table 1. 
The ant, Aphaenogaster carolinensis Wheeler, was collected on 5 
occasions in or near the cixiid nymphal cells. When one stump was 
overturned, an Aphaenogaster worker grasped an O. vicarius nymph 
and attempted to escape. Nymphs were not attacked when placed in 
vials with unfed Aphaenogaster workers. Nymphs were also collected 
twice with another ant, Paratrechinavividula Nylander. These obser¬ 
vations parallel those of Myers (1929) who found an association 
between Odontomachus brunneus Patton and cixiid nymphs of 
Mnemosyne cubana Stal. 
Backlight collections of O. vicarius adults are summarized in Fig. 
1. This trap was located approximately 80 km northwest of the study 
area. Adults were collected only from April through July. Nymphs
