Never come across one of these before! 😍
Apparently it’s a Robin’s Pincushion or rose bedeguar gall, caused by a tiny gall wasp. The female wasp lays eggs inside the leaf bud of the wild rose, she then injects the plant with chemicals that cause it to grow this mossy ball instead of leaves. The grub overwinters inside and emerges in the spring.
Fascinating don’t you think!!
