Julia Stoess apparently works at a German museum, and has perfected the art of making very large (30:1 or bigger) insect models. Check out her site for a gallery of some of her work; she also has photos of the process of making a tiger beetle.
“I have the privilege of working together closely with the Zoological Institute in Hamburg and various entomologists, to ensure that my models are scientifically correct.
After sketching and modelling the individual parts of the body, I take silicone moulds which in turn are cast in resin or laminated. Meticulous selection of the corresponding materials (ageing resistance, UV/synthetic light resistance) guarantees a practically unlimited service life for the model.
I attach particular importance to details such as characteristic hairs and bristles, specific veining in the wings and original colouring.
The aim of my work is to achieve the greatest possible correspondence with the living animal.”
Yay, and congrats on her recent achievement of a World Taxidermy Award!
