Eurosta comma: Benjamin (1934)
The only known host is the Pine-Barren Goldenrod, Solidago fistulosa Mill.
Univoltine. The life history is assumed to be similar to the sister species E. comma; after emergence in the fall mating takes place on or near the host followed by oviposition into emerging shoots and/or the rhizome. Overwintering as egg or early instar with gall formation initiating during the following summer. Pupariation during September-October shortly before emergence.
Generally low, often wet, marshes, roadside ditches, swales, and fields containing the host.
Fall to early winter; peaking in or about October.
