Gnorimoschemine Moths of Coastal Dune and Scrub Habitats in California (Lepidoptera: Gelechiidae)

In California, Gnorimoshema sublerraneum is univoltine ... The larvae cause large, nearly spherical to watermelon-shaped galls (17-27mm long, 12-16 mm diameter, Fig. 102) on stems of Asler chilensis [Symphyotrichum chilense] ... Galls are full sized by March or April, but those taken from the plant prior to late April contain immature larvae ... prepupal larvae remain in the galls until pupation in late summer. Typically, galls occurred 12-1 S cm or more above ground level ... When the stems dry in fall, the galls become woody and persist, sometimes for two or more seasons.
