Remarks
Introduced from the Mediterranean area in the 1970's.

Dr. Elizabeth Jakob has studied these spiders extensively and has published several papers on their habits and behavior. She notes in one article: "These spiders (Holocnemus pluchei) may live alone or share a sheet web with as many as 15 conspecifics of all sizes, and group membership appears to be temporally fluid..."
