Extract

1. The distribution of the larvae of Simulium spp. in the River Tees area is discussed.

2. The dominant species of

(a) the upper Tees are S. monticola and S. variegatum;

(b) the lower Tees are S. equinum and S. reptansvar. galeratum;

(c) the Skerne is S. ornatum.

3. The causes of these differences are unknown, but it is suggested that geological structure, the distribution of water plants and the hardness of the water are important factors.
