Last week I was hiking in Wasatch Hollow, a small nature preserve tucked behind a neighborhood in Salt Lake City. It felt like spring was nudging winter out, and we listened to the sparrows and a cooper's hawk. I'd noticed some interesting galls on the oak twigs and at the tips of the rose bushes. These are, as I understand it, galls caused by wasps.
This one is called a mossy rose gall - and it does sort of look like moss growing at the end, doesn't it?
Now, before flower and leaf buds burst open, is the perfect time to see galls on bushes and trees.
Can you find any galls in your neighborhood?
