Size distribution of Maoridiamesa stouti Brundin (Diptera: Chironomidae): a Madicolous Chironomid from New Zealand

Maoridiamesa stouti Brundin larvae are free living and occur on large stable boulders, but only within the wetted area exposed to the air above the water surface, and generally only on the upstream side of the boulder. The larval size distribution on the boulder surface was studied in a New Zealand...

Description
Summary:Maoridiamesa stouti Brundin larvae are free living and occur on large stable boulders, but only within the wetted area exposed to the air above the water surface, and generally only on the upstream side of the boulder. The larval size distribution on the boulder surface was studied in a New Zealand stream. With the exception of the adults, all life stages were present on the boulder surface. Larvae and pupae were distributed randomly on the wetted surface, but with decreasing mean densities with distance from the stream surface. While 47 madicolous chironomids have been reported in the literature, only four other species are regarded as strictly madicolous. M. stouti has been recorded from stream sites throughout New Zealand.
