Hiking at Volcan Arenal, Costa Rica. I used to take my students here before it became overrun with tourists. This was a strong El nino year, as otherwise it is usually cloudy here in December/January other than very early in the morning.
Jaguar at the mouth of the Rio Claro, Corcovado National Park, on the last frame of film I had that afternoon. This cat subsequently swam across the river (about a meter deep following heavy rainy season storms) and we had an interesting encounter. Do not use this image in any form without my permission.

Tapir (spanish name is danta) walking on the beach near Sirena in Corcovado National Park, Costa Rica. Especially during the rainy season when this park is not heavily visited, tapirs sometimes walk the beach in daylight. Do not use this image in any form without my permission. Copyright J.H Marden.
Two toed sloth (Choloepus hoffmanni; spanish common name is perezoso de dos dedos) in a sea almond tree (Terminalia catappa) near the San Pedrillo station of Corcovado National Park. These sloths can be found often in this grove of trees.
Automeris banus, a common saturniid moth with gorgeous eye spots on the hindwings that are exposed when the moth is disturbed (see next image). It came to a black light at night at the Alberto Manuel Brenes Biological Reserve, near San Ramon, Costa Rica.
Caligo atreus, a large, common butterfly seen frequently along streams and stream side trails. It is crepuscular, flying primarily at dusk. It sometimes comes to headlamps of hikers at night and lands on them, which typically causes some excitement. Damage on the hindwings, from birds and/or lizards is common.
Acharia horrida. A Limacodid caterpillar, Osa Penninsula, Costa Rica. Common name of moths in this family is saddleback. I have not touched one of these caterpillars and I will not do so. I assume that the species name refers to the pain caused by its urticating spines.
