[Jonathan Webster]

I'm not sure how common this will be, but is anyone aware of any arms, crests or badges that feature either spiders or spiderwebs?

I am sure there is at least one other with just a web.

The Intelligence Battalion of the Norwegian Army also has a Spiderweb but also adds a winged Bat's head.
