A Redescription Of The Mature Larva Of Thermonectus Basillaris (Harris) (Coleoptera: Dytiscidae: Dytiscinae), Keith Carroll, E. H. Barman

Georgia Journal of Science

Mature larvae collected from Georgia ephemeral habitats were cul­tured into the adult stage and identified and described as Thermonectus basillaris.The legs of T. basillaris have fewer spiniform sensilla than reported for Acilius mediatus, and it appears that its two large dorsal stemmata are more massive than those of A. mediatus. These morphological differences indicate that nek­tonic larvae of T. basillaris and A. mediatus may be exploiting dif­ferent prey regimes.
