This spider comes out at night and weaves a web. In the morning, she is gone and this is the best picture I've managed to get of her.

Neoscona crucifera is an orb-weaver spider in the family Araneidae. It is found in the United States from Maine to Florida in the east, to Minnesota in the Midwest, to Arizona in the southwest, and in Mexico. Its common names include Hentz’s orbweaver, and barn spider, though the latter nickname suggests the confusion that can result from using common names for spiders, as the name "barn spider" is also commonly used for the species Araneus cavaticus.
