They are among the most famous examples.

All of them were remarkable draughtsmen!

Closer to us, Titouan Lamazou, Yvon Le Corre, Vincent Besançon, Patrick Jager, among those which join again with this tradition which is back again.

A web site http://www.uniterre.com proposes more than 5.000 reproductions.

In our turn, we propose sketch books to you, but only in originals.

You probably know the genesis of our story and understood our concept of new approach to insects collection, mainly Coleopterans. We present below an introduction to the world of coleopterans for amateur entomologists. Learn about coleopterans.

We are pleased to show you here our two very first creations.


Among the 300,000 species of Coleopterans, the Lucanidae family comprises about 1,100 species. They are characterized by sexual dimorphism. Indeed, males, always bigger than females, have mandibles measuring up to one third of their size; they use them to fight against other males, to maintain the female during reproduction, but never to grapple food. This insect is also xylophages (who can eat wood). And, females dig in trees with their mandibles to lay in their eggs. The larva, which can reach, depending on species, up to 100 mm long, will hollow out the wood in which it will live for a period of time up to five or six years. The smallest of lucanus, 5 mm or Vinsonella coeca, comes from Mauritius and measures 10 mm in length at the imago stage, while Cladognathus giraffa, the biggest of all with a length of over 100 mm, can be found on Java island or Nepal.

Stag beetle (Lucanus cervus [Latin: lucanus = kite ; cervus = hart]), originating from Europe, gave its name to the whole family of Lucanidae.

This sketch book, as the next one to be issued, is a part of subsequent products.


The Cetonia sub-class comprises more than 2,600 species spread over warm areas on Earth; it belongs to the phytophagous and floricole Scarabaeo´dae group, for which flowers, plants, fruits and barks are used as food by the imago.

At the larval stage, larva pile up a food reserve of roots and decomposing wood. Ants tolerate their presence; and some larva live close to ants' nest feeding themselves with pieces of plants. They move on their back.

The Cetonia's hard outer wings remain closed when they fly; many species have metallic reflections caused by light dispersion on their unevenly-dimensioned scales which cover their integument, prickles, silks, hairs or other tubercles. The various colors they display make them one of the prettiest species of Coleopterans.

NOTA: On page 33 of this sketch book, the picture II-1.44 should represent a Goliathus atlas female. Unfortunately, we do not have of photo of this species and were unable to reproduce it. If you could help us, we would be very thankful.
