They = were abundant in Kentville by 1999 (e-mail Mar 31, 2006) and likely = present before 1989. I first noticed them on relatively new monitoring = pipe cases which I think were installed shortly after rail to Kentville = was discontinued. Assuming that they did arrive by rail, one would expect them near = sidings that had been poorly maintained (nearby plant growth) while = still in use. Has anyone checked such locations at other rail sidings ? I have seen some near the meadow downstream of Kentville but can't = recall where or when this was. The railyard colony has been extirpated = or much diminished by recurrent cultivation, land levelling etc. Yt. Dave Webster, Kentville ----- Original Message -----=20 From: James W.
