As for the dipteran Simuliidae, the ephemeropterans Americabaetis and Baetodes and the trichopterans
Smicridea and Hydroptila, Carvalho and Uieda (2009a) found a diet based mainly on fine particulate organic matter (FPOM), confirming the importance of the allochthonous material input as a food source for many aquatic macroinvertebrates.
After the rainy months, the flow increased and connected the ponds again, favoring thus the abundance of aquatic invertebrates as trichopterans
, plecopterans, and coleopterans.
Collection of some insect species, such as the trichopteran
Wormaldia shawnee, represented new state records (Wiggins et al.
Dipteran shredders (all Tipulidae) increased from 63 to 89% of total shredder biomass, trichopteran
shredders decreased from 27 to 3%, and plecopteran shredders decreased somewhat less during the first 3 yr of litter exclusion.
The biomass proportions of trichopterans
and hirudineans were also high reaching 8-26% and 5-31% at the studied distances (Fig.
Also identified were trichopteran
tubes and a hygrobatid mite, representing less than 1% in abundance and 1.
and dipteran larvae were the dominant aquatic invertebrates in all streams.

The authors further suggested the high proportion of Trichopteran
larvae in their diets indicated both species frequented hard substrates (e.

and dipteran larva comprised the majority of darter prey items, although a few other taxa, particularly ostracods, were also present (Fig.
