not change position during this time. Only one of three postcopula- 
tory females 1 observed at length changed her location once, about 2 
minutes after copulation, but did not move after this. 
Initially, a spermatophore had an appearance of a whitish, semi- 
opaque, hemispherical droplet, protruding between the terminalia 
of a female. A female manipulated her terminalia so its contents 
passed her genital opening. When it was first visible on a female, a 
spermatophore seemed adhesive and somewhat fluid in shape, 
allowing it to be manipulated on a female’s terminalia. During the 
transfer of its contents, a spermatophore covering seemed to lose 
adhesiveness and harden, allowing a female to dispose of it easily.
