From Andrew Brierley
Alaskan forests are not alone in suffering the ravages of munching
caterpillars
(This Week, 18 July, p 12).
This spring, the Cumbrian fells in Britain were infested with vast numbers of
antler moth caterpillars (Cerapteryx graminis), which ate the
vegetation normally grazed by sheep. As in Alaska, it has been suggested that
this caterpillar plague was caused by abnormal weather.
