Cobweb spiders (Theridiidae)
Southern black widow (Latrodectus mactans)
Web: fairly large, 3D web with messy threads and often vertical threads with glue on the lower part towards the substrate (“gum footed threads”).
Habitat: The Southern black widow has not yet established permanent populations in Belgium. Observations are always the result of unintended hitchhiking from the original range (southern part of USA and Mexico). A lot of Southern black widow spiders are introduced by shipments of second-hand cars from USA in the Antwerp harbour.
