"When a species has 'obvia' as its specific epithet, and it’s so
conspicuous that you can survey its occurrence along a highway at 30
km/h, the English name is obvious. Xerolenta obvia (conventionally
translated as ‘Heath Snail’) lives in open, disturbed limey places with
grasses and herbs, often in enormous numbers. It has a 'medium-sized (to
19 mm), flattened shell, dull to slightly shining, white or grey-white
with a single broad brown spiral band and paler, less distinct bands
below that. It is native to Asia Minor and central Europe.' It was first
discovered in Canada in 1969 near Bethany, along Hwy 7a and an abandoned
railway, and at that time it was speculated to have been introduced
there in the 1940s. Many other populations have since been found south
and west of Peterborough..."
The newspaper took the co-ordinates of the sites mentioned out of the
text -
"We’ve since found them along Hwy 43 from the 416 exit ramp across from
the Walmart (45.03031° N 75.62856° W) to 325 m E of the median of the
416 (45.02831° N 75.62207° W)."
"Breezy Heights Road, 5.7 km S Kinburn (45.34070° N 76.19390° W)" -
