Laurent LeSage and I wrote a paper on Pyrrhalta viburni (the Viburnum  
Leaf Beetle) in the Maritime Provinces back in 2007:

Majka, C.G., and LeSage, L. 2007. Introduced leaf beetles of the  
Maritime Provinces, 3: the Viburnum leaf beetle Pyrrhalta viburni  
(Paykull) (Coleoptera: Chrysomelidae). Proceedings of the  
Entomological Society of Washington 109(2): 454-462.

A PDF version of the paper is available at:

	http://www.chebucto.ns.ca/Environment/NHR/PDF/Pyrrhalta_viburni.pdf

We were the ones that reported the earliest North American records of  
the species from 1924 collected in Annapolis Royal, Nova Scotia.

We posited two possible pathways of introduction:

1. In relation to the early habitations in the area dating from 1605  
(and, indeed, in preliminary data from the area, the proportion of  
introduced beetles in the area of Annapolis Royal appears to be twice  
as high as the provincial average); and

2. In association with the Annapolis Royal Nurseries, the largest and  
most comprehensive horticultural nursery in eastern Canada established  
in 1885. By checking historical catalogues were able to ascertain that  
in 1927 the Nurseries were selling three exotic Palearctic species of  
Viburnum (V. opulus L., V. tomentosum Shasta, and V. plicatum Thunb.).

There is much more detail and information in the paper itself. In any  
event, the Viburnum Leaf Beetle is now widely established in the  
Maritime Provinces including large areas of the mainland of Nova  
Scotia. The earliest records from both Prince Edward Island and New  
Brunswick are from 1995.

All the best,

Chris
