development of the larva may be drastically modified. In the junior 
author’s colony eight males emerged during the period from July 3 
to July 24, 1963. These males developed from eggs which had been 
laid in June of 1962. These eggs developed into larvae in about a 
month and the larvae grew for about two months. But from Septem- 
ber 1962 to June 1963 the larvae showed no further development. 
In short, these eight males over-wintered as larvae. They emerged in 
July and it is interesting to note that the marriage flight of rohweri 
occurs in that month. The senior author took a female of rohweri 
which had just completed her marriage flight in Baboquivari Canyon 
on July 28, 1951.
