Callophrys hesseli angulata (Gatrelle)
Explanation of Names
Patronym for American lepidopterist Sidney A. Hessel
(1907-1974). See Remarks for more information.
Very similar to Juniper Hairstreak - Callophrys (Mitoura) gryneus. Distinguished by close association with a different larval host plant and by coloration. In this species the white markings on the underside are often more striking with stronger reddish brown borders, and are more irregularly arranged on the hind wing, creating a more checkered appearance. The two spots near the base of the hind wing are typically more crescent-shaped. The white band on the front wing is usually nearly straight in C. gryneus, and usually distinctly offset in C. hesseli.
Occurs within the natural distribution of the larval host plant, primarily on the Gulf and Atlantic coastal plain from Louisiana to Maine.
Larval host is Atlantic Whitecedar (Atlantic Cypress) - Chamaecyparis thyoides
From the original description (Rawson & Ziegler, 1950):
"We take pleasure in naming the new species in honor of Mr. Sidney A. Hessel, of Woodmere, N. Y., an enthusiastic collector and student of the Lepidoptera, in whose genial company we took our spring series."
More on Hessel from an Internet source

Yale University Archives
gives biographical information: "Hessel, Sidney Adolphus, 01/01/1907-01/01/1974". However the birth and death days do not look accurate.

Sidney A. Hessel
Just before publication, word came of the death of Sidney Hessel, on November 11. He had been in good health until October 16, when he had emergency surgery, and never fully recovered. Sidney Hessel was a charter member of the Lepidopterists' Society and a strong force in its formation and progress. His counsel will sorely be missed. Most recently, he had served as editor of the Memoirs, and handled back issue supplies and orders. More details will follow in a later issue.
