Across North America.
Goldenrod is the host plant
Life Cycle
Females lay eggs on the undersides of goldenrod leaves. Development from egg to adult takes 4-5 weeks. There are several generations per year. (1)
1. Galls, 2. Larva, 3. Pupae and adults, 4. Adult
Induces flat, circular galls in the leaves of various goldenrods (Solidago). The galls contain a symbiotic fungus, Botryosphaeria dothidea, which the larva apparently does not eat. One to ten or more larvae develop in each gall. Color and size of the gall vary by host species and number of larvae. (1)
The fungus seems to confer some protection against parasitoid wasps. Females carry spores of the fungus.
