AUGUST 5 & 6, 2011 - Pat & I drove to Lunenburg for 2 of the 3.5-day  
Folk Harbour Festival.

On our first afternoon there, on the lawn behind the Lincoln House ex- 
B&B, we found a very-long-bodied female Pelecinidae black wasp that  
hunts and preys on grubs/larvae of May beetles or June beetles under  
the sod.  Very probably this was a Pelecinus polyturator , which  
exists as nearly all females in most or all areas of occurrence.    
The species has a wide range in North America and apparently exists  
under several different names.  Since they are nearly all females,  
the eggs they lay, one at a time on each beetle larva found, must be  
parthenogenic, i.e. not needing fertilization, and probably formed by  
a modified form of meiosis.

Cheers from Jim in Wolfville.
