Methods:

A rock-scrubbing sampling technique was
used to collect samples at several different stations, with two
replicates at each station. Samples were collected approximately every
three days. The same sampling procedure was used for all dates. The
stations were measured relative to the site of the dripper ("-"
= upstream of the dripper).
The samples were preserved in ethanol then picked, sorted, counted,
and measured in Duluth using a digitizing pad.

Notes: All insect measurements are from larval forms unless noted otherwise.
