Articuno, Zapdos and Moltres all have beetles named after them. Binburrum Articuno, Binburrum Zapdos and Binburrum Moltres. They're from Australia and have only been discovered since 2020. They got their respective species names to show how rare they are
the legendary birds but the idea is that they have a history thats a bit similar to the beasts in that they werent always legendary pokemon...they were all originally the same dodrio ^.^
