Our grid at Puerto Bloat is remarkable for the big overmature? Metapocus dombeji, the dense understorey, the absence of "earth". The floor everywhere is soft spongy humus, usually interlaced with roots. We saw not an invertebrate, ot even coming to the rolled out forest (in summer surely mosquitoes etc.). At this season almost no sun reaches the floor, surely not more than 1% of the area sunny on the infrequent occasions when the sun shines. On other trophies a few slugs came to the forest, and dragonflies were flying in sunny intervals. There is a big gap between the great Metapocus (4 to 6 ft DBH) and the smaller nothos (up to maybe 14"), 4-footers are about 200 years old. Other areas nearly have some cyphers, and we had one a few meters outside of the grid but were within the grid. Our baseline (A) was about 10m. in front of the road, as the eastern few rows reached almost to the river, which sets a limit in two directions to the area being studied. Took the boat back to Puerto Banuelos at 4:30 and drove to Humboll's house, met by a fascinating flying cock and path over to the next door. It was about 6:30 and almost full daylight. Set out some traps in the backyard. may 6 Humboll's in Barcelo. Worked on a map of the grid and went out to dinner, but was flying again in late afternoon, visited with Gallopin and Isabel. But was flying at 9° C. may 7 Hilda Humboll says this year the autumn is most unusual. She has roses, lobos, etc still flowering whereas usually they are killed by frosts in March. In the afternoon walked with the Humbolls on the Viscountess de Beret property. The bat did not fly; perhaps has finally migrated?
