Just a New Scientist article about the Common Brown Heteronympha merope
in Victoria (Aus) emerging earlier & having to live longer as a Adult Butterfly as warmer winters are causing problems in their larvae.
The article can be found at;http://www.newscientist.com/article/dn18671-global-warming-changes-natural-event-first-causal-link.html
Here in NZ, we have serveral species that are used to living in the cold (mainly) as larvae, the most notable being the Butler's Ringlet Erebiola butleri
) which lives for months as a larva to avoid predators by not being active on warm clear days (normal Butterfly wether) & presumably survives the winter as a larva.
We also know that Red Admirals Vanessa gonerilla
) aren't keen on hot weather, choosing to take shelter on hot days.
