Horsehair Worm

You're going to have to click and look closely to find this worm. It really matches its name! Look for the thin bluish line in the center of the photo.
Horsehair worms are one of the many 'critters' in Sabino Creek. They can be up to 3 feet long and are as thin as - you guessed it - a horse hair. The larvae live as parasites in the guts of beetles, grasshoppers, and other insects. That's a really small space.
