Okay, here's some additional info from PMPT pb, pg 344-45:
"On April 2, Detective Michael Everett of the Boulder PD called entomologist Dr. Brent Opell of the Virginia State University Department of Biology, who was known as Mr. Spider Man. Opell told the police that there are two general types of spiderwebs. The first, which are called cob or funnel webs, once established are constantly reworked and added to by the spider. The second, manufactured by orb-weaving spiders, is regularly replaced by the spiders and can be completed at any hour of the day, in less than twelve hours. ..... Everett sent Dr. Opell an enlarged and enhanced photograph of the type of web in question. The entomologist said it appeared to be of the funnel type.
"Six months later, on October 25, Everett traveled to Vancouver Island and met with another expert, Dr. Robert Bennett of the British Columbia Ministry of Forests. The detective had with him a newly enlarged and enhanced photograph of the strands of the web that had covered part of the window grate. Bennett confirmed that it was a funnel web."
Bennett also had this to say:
"Spiders hibernate in the winter in temperate zones. Boulder is definitely a temperate zone. Therefore, during winter, there is markedly less or no activity at all by the spiders normally found in Boulder."
