The Entomological Society of Washington (ESW) has met regularly since 1884 and the Proceedings of the Entomological Society of Washington have been published since 1886, making the Society one of the oldest entomological societies in the Americas. The Society extends an invitation for membership to all persons with interest in the science of entomology. The Proceedings are published quarterly beginning in January by the ESW.
The objectives of the Entomological Society of Washington are to promote the study of entomology in all its aspects and to cultivate mutually advantageous relations among those in any way interested in entomology. The Society is organized and operated exclusively for scientific and educational purposes.
