Mischoderus is a primitive cranefly in the family Tanyderidae. The larva differs from tipulid cranefly larvae in that the head is not retracted into the body, and instead of a spiracular disc there is a cluster of tentacle-like tail filaments (or only 2 slender filaments in early instars). There are no thoracic prolegs, but there are prolegs at the end of the abdomen.
Typical habitats
Mischoderus larvae are found in many farmland and bush covered, hard bottom and soft bottom streams, though usually in low abundances.
Feeding
They are known to have ingested a range of streambed foods including plant detritus, algae and midge larvae.
Indicator value
Mischoderus larvae are found in streams with moderate to good water quality. They have mid range tolerance values of 4 (hard bottom sites) and 5.9 (soft bottom sites).
