The UK butterfly count has apparently suggested, in spite of the autumnale August, that species such as the Small tortoiseshell (Aglais urticae) are continuing to recover (http://www.theguardian.com/environment/2014/sep/15/tortoiseshell-butterfly-fights-back-big-butterfly-count). This species has has been seen 'on the wing' and nettle, the food plant, have done well. Having said that, this species can survive cold spells by hibernating as the adult. In my area, there is very little sign of larvae feeding on the nettles. Perhaps the 'recovery' is a bit in doubt. Certainly, surveys (using the same level of intensity) need to be carried out over an extensive period.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
