336. Nicocles dives (Loevv) 

 Large series taken at Hood River in V, VI and VII 

 (Cole and Childs). They have the usual habits of the 

 genus, perching on the tips of dead branches or tall grass 

 stems. From these watch towers they flash out on some 

 unsuspecting little wayfarer whose fate has been written. 

 The silvery tips of the abdomen of the males glitter in the 

 sunlight and are visible some distance away. Aphids, among 

 other small insects, are a part of their food.
