Platerodrilus(Previously Duliticola) is a genus within Lycidae that are commonly referred to as Trilobite Beetles. The common name is derived from the appearance of the females (above), which remain in the larval form during adulthood, a process known as neoteny.
Trilobite beetles are usually found on the surface of rotting logs in lowland primary forest, where their diet is thought to consist of fungi, rotting plant matter and slime moulds. For such an interesting genus, very little is known about their life cycles and there has been minimal taxonomic work regarding the males of the species, which are illusive.
