Wildfire causes disturbance that can alter stream insect assemblage structure and productivity.  We examined the mid-term (5-yr post-fire) effects of wildfire on insect assemblage structure and production using both benthic and emergence samples collected in 2^nd-3^rd order stream reaches with varying fire histories (unburned, low and high severity), within a central Idaho wilderness watershed.  We hypothesized that sites that experienced wildfire would have aquatic insect assemblages with more r-selected primary consumers, that primary consumer production (emergence) would be greater in these sites, and that this would fuel increased production of predatory stream insects.  We found that sites that experienced high severity fire had the greatest biomass of r-selected, generalist primary consumers including Chironomidae, Baetis, and Simuliidae.  This greater prey base appeared to stimulate predator populations, as we also observed the biomass of predatory insects such as Rhyacophila and Tipulidae to be highest in these sites.  Furthermore, high severity sites consistently had greater emergence than low severity sites, with unburned sites falling intermediate.  Our results suggest that the type of fire may have important implications for aquatic insect assemblage structure and productivity, and this could have important implications for stream-riparian foodwebs.
