Moths in Illinois

The state of Illinois has about 1,850 moth species, with the documented ones mostly belonging to the Saturniidae, Erebidae, and Noctuidae families. Some of the beautiful silk moths seen here include the Io moth standing out due to its prominent eyespot, occupying woodlands in late May. Then, there is the yellowish-brown Polyphemus moth and the green luna moth dwelling in forests and woodlands.

The Gypsy moth also found here has been constant trouble for over 20 years, with the IDOA (Illinois Department of Agriculture) constantly monitoring its numbers to control its infestation.
