The genus Pachyrrhynchus of family Curculionidae is striking for it’s spectacular colors and patterns that makes it popular with collectors and entomologists alike. However, there is another aspect that this group is famous for: model for a host of mimic species belonging either to the same tribe, the same family or even different coleoptera families of which the genus Doliops (Cerambycidae) and genus Metapocyrtus (Curculionidae) is very much known. I will talk about this one in a future post.
The photos shown above were collected at a particular forest in the Zamboanga Peninsula. At first, I didn’t notice this one but when I checked the specimens back home, I was just surprised that these three, all occurring in the same patch of wood, were in fact related in patterns to one another. In most cases, the model here is the Pachyrrhynchus sp. (left), probably undescribed. Following it is a Polycatus sp. (center) that almost approximates the elytral and pronotal markings of the former. And finally, a much smaller Calidiopsis sp. (right), that has lost it’s pinkish color due to rigor mortis. This last one is almost similar to the female of Polycatus sp.
These are just two mimic species. Just imagine if the usual species of Metapocyrtus and Doliops can be found and you have spectacular grouping of model and mimics involving five different species!
