British Moths Going to the Dogs

There is a disturbing report about the 'calamitous' decline in UK moths (http://www.guardian.co.uk/environment/2013/feb/01/british-moths-calamitous-decline?INTCMP=SRCH) with at least 3 species becoming extinct and the popular Garden tiger (Arctia caja) showing a profound decrease. The changes are presumably related to modifications of the weather patterns as this alters the growth of plants on which the larvae feed, possible nectar sources that some adults used to 'refuel' and their abilities to fly. Some species e.g. the illustrated Jersey tiger (Euplagia quadripunctaria) have actually increased their range.
