Eggs, final instar larvae, and pupae (male and female) of Bibio tenebrosus Coquillett, B. holomaurus Hardy & Takahashi, B. adjunctus Hardy & Takahashi are described. Except for the larva and pupa of B. tenebrosus, this is the first description of the immature stages of these species. On the basis of careful examination of the head structure, the following characters are suggested to be useful for distinguishing Bibio species : the shape of the cranium, the arrangement of the six sensory pits on the frontal apotome, and the structure of the epipharynx, prementum, and dorsal surface of the stipes. Brief ecological information is also given for each species, and notable morphology of the bibionid larvae and diagnostic characters of the immature stages of Bibio are discussed.
