Leaving Garn -yr-erw there's an area of cleared land that once supported a couple of rows of miners cottages. All that now remains is the green space that was once the back gardens of these properties, complete with remnant garden plants. Flowering garden mint (Mentha sp.) continues to thrive among the overgrown vegetation. As with many flowering plants at this time of year, they prove very attractive to insects. A patch of two metre square mint was home the the giant fly Tachina grossa; a single mint moth Pyrausta aurata and a strong population of green tortoise beetle Cassida viridis.
