Greene, H. 1990 July 5 (continued) here, less than 100 meters distant, yet none on me! From ~2130-2130 hr Wendy Roberts and I walked through the Cantarana Swamp, out to CCC ~700 m, and back through the Cantarana.

The snake was in a loose coil with head extended, horizontal, and scarcely moving--seemed sensitive to the light. A very brightly moonlit night. We also found an exceptionally cryptic caterpillar on a vertical, dirt-fold strand of palm frond (photographs). July 7 Field notes on the first Bufo melanochlois from La Selva, caught by Michael Kaspari (University of Arizona) on June 17, 1990, at Sendero Ribereno 190 m, in litter of large leaves ~1 m off trail, 1040 hrs., partly cloudy and warm. Michael studies ant ecology, and identified the following in two fecal pellets from the little food: 5 Cyphomyrmex cozmita, 5 Solenopsis generata, 1 coccinellid weevil, 1 Cyphomyrmex minuta, 7 Trachymyrmex cornetzi, and 3 Pheidole sinzoni -- all ants except the weevil. Based on Michael's sampling, the food was "selecting the larger ants available." Today I preserved an adult & Gorallus annulatus (1310+253 mm, 510g) and a Sciurus quadratorius that had been palpied from it (365g). Squirrel showed
