Chilostigma itascae, also known as the headwaters chilostigman or Headwaters Chilostigman Caddisfly,[1][2] is a species of caddisfly in the family Limnephilidae.[3] It is known only from mile-long Nicollet Creek in the Mississippi River's headwaters in Itasca State Park, Minnesota.[2][4] It was discovered by Glenn Wiggins, a scientist from the Royal Ontario Museum, on New Year's Eve of 1974, and was scientifically described by him in the following year.[2] Unlike other caddisflies, its adult emergence occurs in the winter.[2]
