Among Tobago’s most captivating butterflies, the Cambridge Blue stands out for its striking metallic blue wings that glisten in the sunlight. Scientifically known as Pseudolycaena marsyas, this butterfly belongs to the Lycaenidae family, often referred to as the gossamer-winged butterflies due to their delicate, shimmering beauty.

Found along Tobago’s forest edges, meadows, and lightly wooded trails, the Cambridge Blue thrives where sunlight filters through lush greenery. Its wings display a radiant cobalt blue above and a soft silvery-grey below, adorned with tiny black markings and graceful tails that help distract predators, a clever natural defence.

Males are often seen gliding swiftly through the air or pausing to sip moisture from leaves, while females visit clusters of wildflowers for nectar. Their gentle movements and vivid colour add a touch of enchantment to Tobago’s natural landscape.

First recorded in regional butterfly studies in the 20th century, the Cambridge Blue remains a cherished symbol of Tobago’s biodiversity. Every flutter serves as a reminder of how vibrant and alive the island truly is, a paradise where even the smallest creatures tell stories of beauty, balance, and wonder.
