D. A. Good 1987 Journal Ublein Cacao, Prov. Guanacaste, Costa Rica 21 August We contemplated going up beyond the crest of the trail to Casa Franka (where the woods is a bit wetter) for night work, but I really wasn't in the mood and when I suggested skipping it, Catfish readily agreed. As a consequence, we went to bed early, and I fell asleep at 7:00 + got almost 11 hours of sleep. Weather, again, windy + intermittent rain 22 August We made another assault on the ridge leading to Ublein Cacao this morning, in hopes of finding more Nototitan, even though the weather hasn't cleared at all so we knew the wind was going to be blowing across the ridge and carrying rain with it. (Left after breakfast ca. 7:00 + got up to 1400 m elev. by 8:30). We stopped at the first likely area with heavily moss-covered Trees + spent ½ hour looking in the moss-found nothing. We then moved up the trail a bit to 1420 m elev. + I soon found a Nototitan - ca. 6 ft up on moss on the side of a vertical Tree. Air temp = 18.2°C, temp in moss 18.6°C. Nototitan seems to prefer thick moss on vertical surfaces. Also, there were various kinds of moss in the area of varying qualities - Some was very stiff + closely adhered to the bark, another was reasonably soft + pliant distally, but the main part of the mat was course + wiry. Neither of these seems popular with Nototitan. All the specimens we have found have been in a third type of moss, which is thick but quite loose in consistency and soft + pliant throughout. This type of moss often hangs in loose bunches from branches + trunks but the Nototitan only seem to be found in moss that is fairly
