Question:
my sister lives in Illinois. while visiting there she was telling me about 2 spiders that come out at night under the eves of her porch, the each weave a web to catch prey, but in the morning there is never a sign of the web, what happens to the web? I looked at different spiders and it might be an orb weaving spider.

From the web site:

http://www.xs4all.nl/~ednieuw/Spiders/Info/Construction_of_a_web.html

"After a night of hunting the web becomes worn out. The spider removes the silk in the morning by eating it, only leaving the first bridge line. After a daytime rest the spider constructs a new web in the evening."

The site includes a series of graphics showing how the web is constructed.

J. Elliott

Some species of spider will catch their food in the evening, then roll their food up in their web and carry it away. If they do not catch anything, they will roll up their web and carry it away to use the next night!
