This square greeting card features a detailed illustration of adders (Vipera berus) entwined in a striking spring courtship display. The artwork captures two snakes coiled together in a flowing dance, highlighting the distinctive zigzag markings and earthy tones that make this species one of Britain’s most recognisable reptiles.
The adder is the UK’s only native venomous snake and can be found across heathlands, grasslands, and woodland edges. During the breeding season, males compete for access to females through ritualised movements often described as an “adder dance", one of the most fascinating behaviours seen in Britain’s reptile wildlife.
