The nocutuid moth Eurois occulta (L.), probably played a major
role here. I read about it in Louis Hanfield's book "Les Guide des
Papillons du Qu=C8bec." ... In short, he argues that the Vikings accidentally introduced the moth, and that the caterpillars became super abundant and ate every green leaf in sight. In support of this, there are reports of caterpillars so
thick on the rocks by the sea that kayaks could not be landed due to the slipperiness of their collective squished bodies. As well, there are layer's in Greenland peat bogs made up of almost nothing but the remains of Eurois pupae. Interesting, no?
...
I think that was in 1985. Back then, no one had heard of global warming. I was taught ... that the climate was cooling at the time I took the course.
