Although uloborids in general seem to construct their webs in the 
early morning (e.g. Eberhard 1972, Lubin and Eberhard unpubl.), 
Miagrammopes are more variable. Thus, while M. simus, M. sp. 1, 
and M. sp. 4 tend to have webs up early in the morning, they, as 
well as the species from Natal (Akerman 1932) sometimes build at 
other times, and M. intempus and M. sp. 3 commonly build in the 
evening. An unidentified species in New Guinea which spins single, 
horizontal threads also tends to build at night (Robinson and Rob- 
inson 1974, M. Robinson, pers. comm.). Readiness to build at dif- 
ferent times of the day might be expected in view of the rapidity 
with which new webs can be made and the small investment of 
material which they represent. The tendency to discard webs sup- 
port this idea. 
Kaston (1964) suggested that the reduced web of Miagrammopes 
is derived from a Stegodyphus- type web (Eresidae) which consists 
of irregularly spaced radii with connecting sticky threads. A web 
similar to that of Sybota (Uloboridae) seems to us a more likely 
precursor of a Miagrammopes- type web. Sybota producta (Sim.)
