Cypress Twig Gall

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.

Cypress Twig Galls Adorn Baldcypress

I came across the galling handiwork of the cypress twig gall midge fly (Taxodiomyia cupressiananassa) on baldcypress while on a photo-trek in southwest Ohio on Thursday.  These spongy, white galls were something of an oddity when I started with Extension 25 years ago.  However, for some reason that has changed with these galls becoming a common adornment on baldcypress.
