Tripartite Tiger Moth (*Nannoarctia tripartita*) on Plum (*Prunus domestica*) – Original h/c engraving by Jacob L’Admiral (1774)

Transformation Recorded Among the Orchard Fruits

This original hand-colored copper engraving by Jacob L’Admiral, published in 1774, documents the life cycle of a moth species observed on a plum branch. The composition integrates ripened fruit, foliage, larval stages, chrysalis, and adult forms within a unified natural setting.

Deep violet plums provide chromatic gravity at the center of the plate, while the successive stages of metamorphosis unfold along the lower register and across the branch. The image balances botanical richness with entomological precision.

The engraving originates from Auwkeurige Waarneemingen Omtrent de Veranderingen Van Veele Insekten (1774), one of the Dutch Enlightenment’s significant contributions to early empirical entomology.

Visual Structure & Sequential Observation

The composition is diagonally dynamic. The fruit cluster anchors the upper portion of the plate, while larva, chrysalis, and adult moth are arranged methodically below, transforming the lower margin into a platform of evidence.

Color application is disciplined yet expressive: the saturated purples of the plums contrast with the earthy browns of the larvae and the subtle tonal gradations of the moth’s wings. The engraving demonstrates L’Admiral’s ability to integrate aesthetic appeal with scientific sequencing.

Scientific Context

In the eighteenth century, insect metamorphosis was increasingly studied in relation to agricultural environments. By observing species directly on their host plants, naturalists contributed to both theoretical understanding and practical horticultural knowledge.

L’Admiral’s plate reflects this Enlightenment emphasis on observation over speculation. Transformation is presented as verifiable process, documented patiently and engraved with clarity. The work stands at the intersection of cabinet curiosity and applied natural science.
