For the convenience of anyone desiring information on the family Geometridae, order Lepidoptera, the following list of species reported from Iowa has been prepared. The Geometridae are universally distributed in all parts of the world where vegetation is found. They are rather frail in structure, with considerable expanse of wing in relation to the size of the body. They are either semi-diurnal or crepuscular. Over 800 species of Geometrids are known to occur within the limits of the United States and Canada, of which 61 have been found in Iowa. This number could doubtless be greatly enlarged by more intensive collecting.
