I crash through and inadvertently destroy countless spider webs on my treks through the forest - but there's one web I don't blindly blunder into - the web of the Spiny Orb Weaver, (Gasteracantha cancriformis). Her web is easy to see because she thickens every fourth centimeter of the frame and support threads with extra silk. Surely, the Spiny Orb Weaver does this out of instinct and does not know that in doing so she is outlining her web with caution tape. There is definitely an advantage to this behavior: Upon completing my 1.5 mile walk this Friday, there were 23 in-tact spider webs in my wake - 23 Spiny Orb Weaver webs. That's got to count for something!
