Hi Ian,

In John Gilhen's Reptiles & Amphibians of Nova Scotia (1983) he has  
it indicated as occurring on Brier Island so its been known from  
there for some time. On John's distribution maps I don't see any  
other islands indicated (other than, of course, Cape Breton Island  
where they are widely distributed), so their presence on Brier seems  
to me to be noteworthy.

As to its origins, I suspect they reached Brier on their own steam  
rather than being released as pets. This might have been as long ago  
as post-Wisconsinian glacial times when sea levels were depressed and  
Brier might have been connected to the mainland. There are a number  
of flightless beetles found on Brier Island. Some of these are  
introduced Palearctic species which would have been brought there via  
human agency, but they also include native ground beetles like  
Sphaeroderus stenostomus lecontei Dejean and Pterostichus coracinus  
(Newman) which must somehow also have reached Brier on their own.

It is a fascinating subject. In press, at the moment, is a paper on  
the preliminary results of a "bio-blitz" on Scatarie Island, where  
again a number of flightless beetles have been found. Sable Island  
also provides some fascinating examples, most notably the flightless  
tenebrionid, Ephalus latimanus (LeConte), which is found in Canada  
only on Sable Island. It is a coastal species whose northward extent  
in New England terminates in southern Maine.

Cheers!

Chris
