While not endangered, Brimstone Butterfly's caterpillar relies on Alder and Common Buckthorn to survive.

Volunteer Sue Cox, who looks after Somerleyton station near Lowestoft under Greater Anglia's Station Adoption initiative, last year planted a Buckthorn hedge to help with Suffolk Butterfly Conservation's Brimstone and Buckthorn project.

"We often see first generation Brimstone Butterflies here in early spring, emerging from hibernation on a warm sunny day to look for nectar and mates. But we very rarely see the second generation," said Sue.

"So I was rather pleased to see a very fresh, very green male Brimstone nectaring on the Wild Pea on the platform at the beginning of August."
