Adze: The West African Vampire That Hides Inside a Firefly

The Adze is a vampire figure from the Ewe people of Ghana and Togo, and it is one of the most unusual in world folklore because of the form it takes. In its natural state the Adze is a firefly. It flies through the night in this form, entering houses through gaps in walls and windows, and feeds on sleeping people by drinking their blood, coconut water, and palm wine. If it is caught in its firefly form, it transforms into a human being, and in human form it is a witch whose powers include the ability to possess people and cause wasting illness and death.

The combination of a beautiful and familiar natural creature, the firefly, with predatory supernatural behaviour gives the Adze a distinctive quality. The firefly is not an obviously threatening creature. It is small, luminous, and associated in many cultures with wonder rather than danger. The Adze tradition inverts this entirely: the light you see moving through the darkness at night might be something hunting you.

The Two Forms

The distinction between the Adze’s firefly form and its human form is one of the most important structural elements of the tradition. In firefly form it is relatively constrained in what it can do: it can enter houses, drink from sleeping victims, and spread illness through its feeding. In human form, forced on it when it is captured, its powers expand considerably into the full range of witchcraft abilities that the Ewe tradition associates with supernatural evil.

This two-form structure creates an interesting dynamic in how the tradition functions socially. A firefly in the night is something everyone can see and most people would not associate with danger. An accusation that a specific person was the human form of an Adze, revealed through capture, was a much more serious social event with real consequences for the accused person and their family. The Adze tradition gave a framework for understanding illness and misfortune that could, in practice, be used to explain why specific individuals in a community were dangerous.

What the Adze Caused

The illness the Adze caused was primarily wasting disease: victims grew gradually weaker, thinner, and paler, losing their vitality over an extended period rather than dying suddenly. This pattern of slow decline was consistent with the creature’s feeding method, which drained incrementally rather than all at once, and it made the Adze an explanation for the kind of illness that resisted obvious treatment and that seemed to consume a person from within.

Children were particularly vulnerable in the tradition, consistent with the targeting of the young that characterises vampire traditions worldwide. The sight of a child growing thin and weak despite apparently adequate food and care was one of the most distressing experiences available to a pre-modern community, and the Adze offered an explanation that located the cause outside the child and outside the family, in a specific supernatural agent that could in principle be identified and neutralised.

The Adze in Context

The Adze belongs to a broader West African tradition of supernatural beings associated with witchcraft, night-flying, and the consumption of human vitality. Its closest relatives in the regional tradition are the various witch figures of Akan, Yoruba, and other West African cultures whose abilities include nocturnal transformation and the draining of life force from victims. The specific firefly form of the Adze is unusual within this broader tradition and may reflect particular local observation of the firefly’s light as something mysterious and potentially threatening in the dark.
