Proceedings of the United States National Museum SMITHSONIAN INSTITUTION . WASHINGTON, B.C. Volume 114 1964 Number 3475 MOTHS OF THE FAMILY ACROLOPHIDAE IN AMERICA NORTH OF MEXICO (MICROLEPIDOPTERA) By Frank F. Hasbrouck^ Introduction The ACROLOPHIDAE, a family of small to medium moths of predom-inantly brownish coloration, have no common name and are not of great economic importance in the United States; but the larvae of these moths, sometimes known as "burrowing web worms," attack grasses (including corn), bromeliads, and orchids, usually feeding on the roots. The group has long been in need of a monographic revision. These insects, presumably limited to the Western Hemisphere, exhibit perhaps a greater affinity toward the Tineidae than toward any other family in North America. The literature referable to the North American segment of this family is not extensive and is largely con-fined to the original descriptions of genera and species. Accounts of the immature stages of the species are quite rare. Since the appear-ance of MejTick's four species in 1919 no new acrolophids have been described from the United States, and the literature has exhibited very little new information of any Idnd regarding the family.
