Thanks Marg -- particularly interesting to me because we lived just  
north of Washington DC, in Bethesda, in 1969-70 and were swamped by a  
17-year emergence early one year.  Our infant son, left outside the  
cottage in a playpen, actually ate half of one.  A possum, the only N.  
American marsupial, makes a brief appearance in the video (about to  
eat a cicada), and we used to see one occasionally at night there,  
climbing around a nearby tree.
   It was widely reported that this cicada mass emergence happened  
again this year, 2013, in the same area of Maryland.  But if you keep  
adding 17 to 1970, the nearest predicted year of emergence would be  
2021, not 2013 -- the math doesn't fit.
   Thanks to details on the Magicicada link on this site that Marg  
turned up, the mismatch can be explained.  We would have experienced  
the emergence of the largest eastern brood, 'X' in 1970 which will  
next emerge in 2021, while the current 2013 emergence was of a  
different brood, 'II'.  The two overlap spatially in Maryland. Minor  
mystery solved thanks to NatureNS.
   Agreed, it is well worth looking at the video, and the links.
Steve, Halifax
