Pierre Lyonnet or Lyonet (21 July 1706 – 10 January 1789)[1] was a Dutch artist and engraver who became a naturalist.

[2] According to the RKD he was a pupil of Hendrik van Limborch, Carel de Moor, and Jan Wandelaar.

Initially he trained as a lawyer before choosing to specialize in the engraving of natural history and the work of dissection.

His book was received with scepticism which affirmed that Lyonnet imagined the details which he drew with so much precision.

Lyonnet planned to study the chrysalis and the adult but, sixty years old, the tiredness of his eyes obliged him to stop his projects.
