摘要：We reared field-collected egg masses of the caddisflies Phylloicus amazonas (n = 2) and Phylloicus elektoros (n = 7) to adulthood. First instar larvae of both species hatched up to five days after field collection. Median development time from first larval instar to adult was 229 days for P. amazonas and 275 for P. elektoros, including the pupal development time (median of 13.5 and 16 days, respectively). Shredder organisms have been used frequently in studies related to organic matter processing in freshwater ecosystems. The biological information reported in here may be useful for the design of experimental studies in the field or under laboratory conditions.
