Cypress Twig Gall Midge Fly

First Generation Galls Appearing on Baldcypress

First generation galls produced by the Cypress Twig Gall Midge Fly are nearing maturity and are very apparent on baldcypress in southwest Ohio. The spongy, snow-white galls are most commonly found on baldcypress where heavy galling may occur year-after-year on highly susceptible trees. Galls may also arise to a lesser degree on pond cypress.
