SHORT COMMUNICATION 



Stigmus pendulus (Panzer) (Hymenoptera: Sphecidae) associated with ancient 

 woodlands in south-east London. — Since Stigmus pendulus was first discovered in 

 Britain by Allen (1987) it has remained rather a mystery. At the time of Falk*s review 

 (1991) it was known only from Allen's original East Kent specimen and two more 

 from the other side of the Thames in South Essex. Published records seem few: UtTen 

 (1997, 1998) has recorded it twice from Hertfordshire. However, it is obviously much 

 more widespread and there are many more records from South Essex (P. R. Har\e\ . 

 personal communication) and Surrey (Baldock, in preparation). 1 was not. therefore, 

 too surprised to find it at several localities in the London area. 



What I did find surprising, or at least ironic, is that here it seems to be associated 

 with ancient woodland! So far Stigmus pendulus has been found at four sites. 



Sydenham Hill Woods. Dulwich (TQ3472. Surrey). 20.vi.1993, 30.viii.1993, found 

 by D. W. Baldock in 1997 in Malaise trap material which had been stored in alcohol 

 for several years. Sydenham Hill and Dulwich Woods are reckoned to be remains of 

 the "Great North Wood", a series of oak copses and wooded commons extending 

 through south-east London from Selhurst to Brockley. A large number of
