Pseudanidorus vigilans

Pseudanidorus vigilans is a species of ant-like leaf beetle in the family Aderidae. Members of this family are characteristically small, elongate beetles with a superficial resemblance to ants, a trait that likely serves as protective mimicry. The genus Pseudanidorus contains few described species, and P. vigilans appears to be rarely encountered based on available records. Like other aderids, it likely inhabits moist, decaying wood or leaf litter environments where it feeds on fungal hyphae.
