I visited the the Lago Atitlan area (and nearby pacific foothills) during Feb 26 - Mar 03 2006, while attending the Second International Birdwatching Encounter in Guatemala.
It was primarily a birding and eco-tourism trip, but I looked for butterflies whenever I could. It was the dry season there, and I saw very few blooming nectar plants, and very few butterflies - I was told that during the wet season (May - Oct) there are tremendous numbers and variety of butterflies in this region:
A)
White-spotted Clearwing Greta annetta annetta .
B)
Crimson Patch Chlosyne janais ssp?:
C)
Yellow-striped Gemmed-Satyr Cyllopsis nelsoni ?:
D) Napaea Satyr Pedaliodes napaea - ?:
note red band on trailing edge of upper HW:
E) Azure Celastrina sp.:
