The females and larvae have a flattened, dark body with large scales over the head, resembling trilobites, hence the informal names trilobite beetle, trilobite larva or Sumatran trilobite larva. In contrast, the males are much smaller, 8–9 mm, resembling other lycid beetles. Species are found in tropical forests of India and South-east Asia.
Leptolycinae is a subfamily of the Lycidae or "net-winged beetles" erected by Leng and Mutchler in 1922. [1] This subfamily includes notable genera such as Platerodrilus , which are sometimes called "trilobite beetles".
Some trilobites had horns on their heads similar to several modern beetles. Based on the size, location, and shape of the horns it has been suggested that these horns may have been used to combat for mates. Horns were widespread in the family Raphiophoridae (Asaphida). [86] Another function of these spines was protection from predators.
Trilobites were arthropods, like modern insects, spiders, millipedes and crustaceans, and they evolved into a wide range of shapes and sizes before going extinct around 252 million years ago. Most ...

Trilobite larva may refer to juvenile forms of multiple unrelated groups of animals: Trilobites, extinct arthropods; Xiphosura (horseshoe crabs), including living and fossil species; Platerodrilus or trilobite beetles, a genus of living insects
The xenomorph's design is credited to Swiss surrealist and artist H. R. Giger, originating in a lithograph titled Necronom IV and refined for the series's first film, Alien. The practical effects for the xenomorph's head were designed and constructed by Italian special effects designer Carlo Rambaldi. Species design and life cycle have been ...
