Wyer phil 1972 Journal 5 Ave Cral Genes, 1.6 km NE jcn we San Martin' Asuncion, Paraguay (jun aut.) 1-8 June 2 obious termib types, one maki sbo large black tle nest & cared trails over branches, which is common in traying & no maki covered trails of sand across the groun? Best arthropods to see are the social spiders. Hundreds of individuals to a colony, each individual ~ 1/4 - 3/8" long, & mostly black w. red markings on the dorsum & sides of abdomen. The web is really hundreds of individual webs spun between shared guy line (from tree to tree, tree to ground, etc). i.e., [illegible] each weblet ~ 3-4" in diameter. each individual web is tended by one spider. This system results in a remarkably even spacing of the adults in the web. Spacing is enforced by a signal where a spider shakes his web when a neighbor comes too near. at night all spiders leave the main web & cluster into silk structures in the tree at the edge of the web. looks like a neat system, & worth examining. Trapping - we set only live traps.
