A befuddled bicycle rider recently wrote to the Albuquerque Journal concerning the sudden appearance of spiders painted on bike lanes in the city.
“Riding my bicycle throughout the city, I have spotted stenciled spiders in various colors in the bike lanes,” the note to the Journal said. “I was thinking they were some kind of signal.”
According to the bicycle rider, the spiders were 12-14 inches in size in shades of yellow, red, blue, green, purple and other colors.
A spokesman for the city said no one knows who is painting the spiders or what their meaning might be. They are considered to be graffiti, so they are being erased as soon as they pop up, they said.

Better painted spiders than this real spider hatch spotted on a street in Vancouver, British Columbia, some time ago.
