Observational subject:

Same web as in 002.

Vegetation/macro location:

As before


11.30. Web looks thinner and scantier since seen 18 hours previously. Volume taken by spiderlings seems less, suggesting either less spiderlings or that they are huddling more tightly. Two formations seen, a vertical sausage shape and a separate small ball. Both have a reduced surface area to volume ratio compared with the more diffuse shape of yesterday. No adult seen, very little activity indeed compared with yesterday.

Formation consistent with heat conservation.

12.15: No further activity noted and as I was getting cold (being unable to rapidly reduce my surface area to volume ratio), study ended.

    Hey there Vincent! Great to see that you are still out there active in your conservation/naturalist work. Saludos! – Mark
