Fig. 10. Distribution and abundance of order Trichoptera in the Nee Soon drainage. Solid 
circles indicate sites where representatives were collected and circle sizes are proportionate to 
abundance/numbers of individuals captured as reflected in the accompanying legend. 
diverse and widespread worldwide, having adapted to many different environments 
and modes of life (Yule & Yong, 2004). However, in the Nee Soon catchment they 
appear to be quite rare, being only found in a few scattered locations in low numbers 
(Fig. 11). Members of this subclass were only found in four sites (sites 4, 7, 31 and 
34), with the most abundant site (site 31) having a total of four individuals. Freshwater 
mites in both adult and larval stages are usually predators or parasites, feeding off 
other organisms such as insect larvae.
