Gallformers ID Notes
“
Globular, often tooth shaped galls located on the ventral midrib of Salix irrorata leaves. The majority of the gall shows on the ventral surface but a small portion is often visible on the dorsal side of the leaf. Galls are either red or green, and the interior is completely hollow with very thin walls. Sometimes galls are strongly lobed, which may suggest that galls can grow close enough together to coalesce. In dissected galls frass was found inside, which shows that the inducer is likely a sawfly rather than a Cecidomyiid.
