In general, larvae foraged and added to their cases along the 
floor-wall junctions, or out on the floor at night, and rested at the 
bases of the walls or up several centimeters on them during the day. 
Occasionally a larva was seen moving about during the day. Usually 
each larva returned to, or near to, the spot where it had been 
recorded the day before. Most stayed within 30-80 cm ranges, with 
an occasional sudden change from one wall to another. For exam¬ 
ple, individual “6” was frequently found out on the floor at night, 
but rested against the wall under the sink by day. After ten days of
