Willow Pinecone Gall

Weird Willow Gall

Arguably, one of the weirdest galls found in Ohio is produced on willow by the gall-midge, Rhabdophaga strobiloides (family Cecidomyiidae).  The gall's appearance isn't weird; it looks like a pine cone.  However, finding a "pine cone" on a willow is weird.  As the common name implies, the Willow Pinecone Gall, which is sometimes called the "pine cone willow gall," closely resembles a pine cone with closed seed scales.
