Eukiefferiella is a genus within the orthoclad subfamily of the Chironomidae. Like other chironomids the general body form is worm-like, but with a distinct head, and with paired prolegs under the head and at the end of the abdomen. The larvae tend to have a green body and small brown head. Some Eukiefferiella species attach themselves to mayfly nymphs. If not attached to mayflies they are probably often simply recorded as “orthoclads”.
Eukiefferiella larvae are found in a wide range of stream types.
Species within this genus are known to feed on streambed algae and organic detritus.
Eukiefferiella can be found in high quality streams (along with their mayfly hosts) but this genus has not been assigned tolerance values. Therefore we only have the low tolerance values for the orthoclad family, which are 2 (hard bottom sites) and 3.2 (soft bottom sites).
