Greene, H. 1987 27 November plennifrons asleep at 2m upon a Heliconia leaf (continued) in front of the main lab (115g, 151+494mm). She struggled, gaped, elevated tongue, and tried to bite when seized. 28 November Sick all day, it's have been several other people. Upset stomach, headache, weak and sore muscles. The ? Bothrops asper was coiled in the "resting" place at 1100hr and 1550 hr, but not visible at either site at 2100hr. Where is she? Not pleasant looking for her at night... Beth Newell saw a tricolored Micrurus (?) by her cabana after dark. 29 Novemr Feel better this morning. At 0750 hr I found the ? Bothrops asper back in her resting site. When I moved leaves near her head, she jerked her head up and in my direction and froze - no tongue flicks, tail movements, etc. I slipped away, and returned at 0757 to find her quiet again. From at 1030-1300 hr walked the CCL and CCC with Carmen Rojas, at at 1330 I found the B. asper at her "resting" site, then walked to 500 m on CES and back, to 500m SOC and back, and checked the B. asper again at 1500hr. Walked in the Cantarana swamps from 2100-2130h and saw a few Hylla leguayi and one small golychmic colidryas, and photographed some spiders, including an arboreal tarantula.
