Strolling around the garden in the evening, Rosie pointed out an unusually green spider, about the size of a small pea. It stood out in the evening sunlight.
Araniella cucurbitina is commonly called the 'green cucumber spider' and this one is probably as big as they get. They are difficult to see against green foliage.
There was also a peppered moth on a nearby planter. I studied this species as part of my degree course. In those days, the melanic (black) variant of Biston betularia was very common. With improved air quality, the common form is now more abundant in many areas.
