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.
