Branches

ESA's Branches are designated on the basis of geographical contiguity for the purpose of holding meetings, providing an opportunity for presentation of papers, and stimulating interest in entomology.

ESA members automatically become members of geographical branches based on the mailing address they provide. Each branch has elected officers. An annual meeting is held in each branch so that members benefit from interacting with others in a specific region and sharing scientific information on topics of interest to that region. Foreign members may choose any branch affiliation or none.
