sub adult black train millipede

The black train millipede, scientifically known as Tynomus garmani, is a species of millipede characterized by its elongated, segmented body and dark coloration, often black or dark brown. It is typically found in various habitats across North America, particularly in moist environments like leaf litter, soil, and under logs. Despite its intimidating appearance, it is generally harmless to humans, feeding primarily on decaying plant matter and small invertebrates. Its name may derive from its robust, train-like appearance, and it plays a vital role in the ecosystem by aiding in the decomposition process.
