Larval distributions of the nuisance midge Glyptotendipes paripes in three central Florida lakes occurred in two patterns, predominately on lake periphery firm sediments (type 1), or primarily on soft organic sediments at lake center (type 2). Larval distributions were investigated in relation to sediment dry weight, particle size distribution and physical composition (muck, sand , frass, clay, or detritus). In agreement with previous results, the soft organic sediments in the type 2 lake had large to predominant amounts of chironomid frass while frass was very limited or absent from the soft organic sediments of type 1 lakes.
