There are so many wonderful moments of discovery when we immerse ourselves in the natural world. On Sunday, we found a thistle gall on creeping thistle (Cirsium arvense) by the pond. It’s the first one I’ve seen, or noticed, and I was keen to explore more.
The thistle gall fly (Urophora cardui) is a beautiful black and white fly. For readers who are interested, here are a couple of links. http://www.naturespot.org.uk/species/thistle-gall-fly .
