Birds, mammals and plants are commonly seen in painting, sculptures, heraldry &c but seldom insects or other invertebrates. In fact, the only one I can remember is this carving on a mediaeval building in Arles, southern France:
I presume the insect is a cicada although it does look a bit like a bristletail - any other offers?
