Can you identify these 4 butterflies please?
First and second butterflies (below) seen in the Iguacu Falls national park in Brazil in January 2013.
Third butterfly from April 2012, taken near Leigh-on-Sea in Essex / Thames Estuary.
And finally this one taken in La Camargue in France in June 2012.
Thanks for your help!
1. No idea, sorry.
2. Looks a like a Heliconiid; lots of species...
3. Green-veined white (Pieris napi), male
(good guide here - http://www.ukbutterflies.co.uk/species_family.php?name=Pieridae).
4. Marbled white (Melanargia galathea)
There are several species of Melanargia in Europe, but this is the same as the one found in the UK.
