On a return visit to Tuff Crater in January I spent some time watching this butterfy feeding on Muehlenbeckia complexa on the edge of the tidal sea-water filled crater. Originally this butterfly was identified as a common copper but a professional lepidopterist at landcare has now identified it as Rauparaha’Copper, Lycaena rauparaha. This is another species to add to the Tuff Crater list.
