during July or August (Table 1) . Because this survey was not 

 formally initiated until the first week of June, little work was 

 accomplished during May, which may be the best time for observing 

 pairs (Wallen and Groves 1988, 1989; Cassirer 1989). No surveys 

 were conducted during the first half of July because of the low 

 probability of observing harlequins during this time.
