The Entomological Society of Pennsylvania (ESP) mailing list has been established for members to exchange information on insect collecting, biodiversity projects, upcoming events, general entomology, and whatever other insect/Pennsylvania related items they'd like to discuss. Anyone interested in membership should contact the list owner. Yearly dues are $8 ($5 for students). A newsletter is produced several (3-4) times per year and an annual conference is held in Pennsylvania.
