Small Purple-barred (*Phytometra viridaria*) on Wild Strawberry (*Fragaria vesca*) Hand-col. engraving by Jacob L'Admiral (1774)

Wild Strawberry and the Small Purple-barred

This original 1774 hand-colored engraving by Jacob L’Admiral depicts the Small Purple-barred moth (Phytometra viridaria) within a richly observed study of wild strawberry (Fragaria vesca). The composition brings together flowering stems, ripening fruit, and multiple life stages of the insect in a harmonious botanical setting.

The broad, textured leaves of the strawberry plant create compositional weight, while suspended adult moths introduce movement within the expansive white field.

The result is both scientifically articulate and visually inviting.

Visual and Aesthetic Analysis

The interplay between fresh green foliage and the warm red berries provides natural chromatic contrast. The moths’ violet-blue and amber tones add subtle luminosity above the plant canopy.

The plate reads almost as a botanical still life, with the insect narrative integrated seamlessly into the vegetation.

Scientific Context

L’Admiral’s 1774 work systematically documented metamorphosis and habitat relationships. By situating the moth directly on its host plant, the engraving reflects the Enlightenment emphasis on ecological observation.

The inclusion of larval and pupal stages underscores the didactic purpose of the publication.
