In August, I spent 12 days in Costa Rica with a couple of friends from Arizona. It was fantastic to see this lovely country again and see the changes that have occurred since my student days in 1980. Eco-tourism has been highly successful and there were lodges and infrastructure all over the areas that we visited. We did not have much time so decided to visit areas that were not far apart to reduce the time lost to transfers. August was one of the wet months but the rain was never excessive and we always had a few hours of sun each day.

This will be a large post and will include shots of plants and other animals as well as butterflies. I will add to it for the next week or so. I will also add costings to the end of the report.

Our itinerary included the following stops:
1) Suena Azul, a lodge in Horquetas. We spent a single night while awaiting the tractor ride to Rara Avis the following morning.
2) Rara Avis, a remote lodge on the southern boundary of Braulio Carillo NP. This was a beautiful place located at about 700m elevation on the Caribbean flank of Volcan Barva. It was an extremely wet place. Branches and trunks of trees were totally covered with epiphytes.
3) La Selva Biological Station. We spent three nights at this lowland sites.
4) Observatory Lodge, Volcan Arenal. We spent three nights at this mid-level site.

I will begin this post with the photos from La Selva. In 1980, I spent a number of weeks here while studying birds from a canopy tower. Now, I could hardly recognize the reseach station. La Selva has a huge amount of new accommodation, labs, libraries and the like for the biologists who are studying various aspects of tropical ecology. In 1980, access to the reserve was via a boat trip up the Sarapiqui River from Puerto Viejo. Now, there is a road and bridge access. The old muddy trails that I used to follow were mostly paved within 2kms of the headquarters. Once I walked far back into the reserve, I reached the muddy trails that were more familiar to me. La Selva is really a top place to visit with so much to see.


RAINFOREST INTERIOR
The following shot illustrates the location of La Selva. The watershed above it is protected all the way to the top of Volcan Barva.


La Selva is mostly covered with lowland rainforest.





Many of the trails were paved like this. They were wide enough for bikes that could be hired at the headquarters.




I saw Banded Owl Butterflies (Caligo atreus) once or twice each day in the forest interior. These remind me a little of Koh-i-Noor in behaviour since they will flush, fly maybe 20m or so and then land on a tree trunk. I did see other Owls but this was the only species that I was able to photograph.




Satyrinae were numerous in the forest. Some of these were nicely marked. As always, there was a bewildering array of similarly marked species. After lots of study of the online guide, I think that I can recognize a few but others were just too confusing.

Jesia Satyr (Euptychia jesia)
