 Wasps leave the galleries where they lived 

 as larvae in the months of June and July and 

 display their talents as miners and hunters in 

 the following months of August, September 

 and October. 



Does a similar law apply to the Hairy Am-

 the work of the burrow at the end of March 

 would in that case have to complete her 

 metamorphosis and to break out of her
