A Korean cockroach
Actually, it’s supposedly some form of ground beetle.
Model by John Montroll. Folded from diagrams found in Origami For The Connoisseur. (I absolutely cannot spell “connoisseur” without looking it up.) I used a 20 cm square of fairly thin hanji. This was only the second time I’ve folded the model – the first time was a few days before, from a 15cm square of ordinary origami paper (often referred to as kami), just to get a feel for what the folding sequence was. That paper was too thick to properly finish the legs and antennae, but I had no problem when using the hanji.
