Slender Sac Spider
(Chiracanthium sp.)
The Sac Spiders include spiders which build characteristic chambers in which to hide themselves for moulting or egg-laying. The chamber is formed from a folded blade of leaf, sealed with a thick layer of silk. Occasionally, a larger chamber is made by fastening several leaves together.
