to that found at Legon in the flight of male doryline ants (Leston, 
1978), falling within the first wet sunny season (Gibbs & Leston, 
1970). It coincides too with that of alate sewing-ants, Oecophylla 
longinoda (Latreille), in the forest zone: again a wet sunny season 
event (Leston & Gibbs, 1971). 
But the apparent trimodality of the paussids does not fit just into 
the two wet sunny seasons of the forest zone although the October 
peak falls within the second of these. Were it not that a similar 
trimodality has been detected elsewhere it might have been dis- 
missed as a peculiarity of the particular period sampled but a range 
of mantids sampled at Tafo, 35 miles north of Legon and in the 
forest zone, had a similar pattern (Leston, 1972).
