Mangrove St. Andrew's
Cross Spider

Argiope mangal
Family Araneidae

Size:
female 5 mm, male 2 mm

Mature females spin an orb web 38-50cm long which usually only contains two silken zig-zag bands (stabilimentum), unlike its inland counterpart A. versicolor, which spinds the characteristic found bands resembling the cross of St. Andrew's.

Other spiders on the web include the smaller males and sometimes, iniquiline spiders. When disturbed, it either speedily switches to the opposite side through a gap in the web, vibrates the web edge or remains motionless after running away or dropping off the web.
