Spiny orb-weaver
From Wikipedia, the free encyclopedia
Spiny orb-weavers
Spiny orb-weavers is a common name for Gasteracantha, a genus of spiders.
They are also commonly called Spiny-backed orb-weavers, due to the prominent
spines on their abdomen (cf. genus Isoxya). These spiders can reach sizes
of up to 30mm in diameter (measured from spike to spike). Although their
shell is shaped like a crab shell with spikes, it is not to be confused with
a crab spider.
Orb-weavers' bites are generally harmless to humans.

One of the more colorful spiders in Florida is the spinybacked orbweaver,
Gasteracantha cancriformis (Linnaeus) 1767. Although not as large as some of
the other common orb weavers (e.g.; Argiope, Levi 1968; Neoscona, Edwards
1984), the combination of color, shape, and web characteristics make G.
cancriformis one of the most conspicuous of spiders. The colloquial name for
this spider in parts of Florida is "crab spider," although it is not
related to any of the families of spiders commonly called crab spiders, e.g.
, Thomisidoe.

有花斑，还带刺儿，但无毒，看来是吓人的。
