Brimstone (Gonepteryx rhamni): The Brimstone is a great wanderer and, as one of the longest-lived UK species, can be seen in almost every month of the year. There are two distinct emergences; one on the first warm days of spring and the other in high summer, when the butterfly is seen nectaring on plants like thistles and wild teasels to lay down a layer of fat for hibernation. The female, which is nearly white, compared to the bright yellow of the male, lays its eggs on buckthorn or alder buckthorn in spring.
