It might seem unlikely, but in spite of centuries of science and of expanding our knowledge of the Earth, there are so many species we still know nothing about their lifestyle, ecological requirements and threats. This is typically the case of species occurring in remote areas or prohibitive habitats, but it also applies well to many organisms inhabiting the Old World, perhaps they even inhabit your backyard or the grasslands you walk in during your weekend hike. One of such species is the beautiful Campilomphus homalisinus, a small and inconspicuous Mediterranean click beetle, which I have enjoyed writing about a few years ago.
