T. fucicola is the larger of the two Tarphiota species present on the sandy beach. These beetles range from 3.0mm to 4.0mm and are more robust than T. geniculata. They have small golden hairs throughout most of their body. T. fucicola are rare with little pattern to their occurrence. Like most rove beetles, they can be found more frequently within spring and summer months and in humid kelp. Their diet is mainly through scavenging decaying arthropods, but may include small fly larvae.
