本文从5°~ 25°C的代谢温度曲线和呼吸代谢的总幅度，以及在法国罗纳河流域部分河段的分布，以及在这些河段中水螅科的共存种等方面，分析了其在河流连续体中的地位。代谢数据清楚地表明，外ellata是一种适应马铃薯的物种，但分布数据并不能证实代谢结果。例如，在罗纳河的下游和河流中没有发现exocellata，而在新陈代谢方面，它又经常与pellucidula共存，这表明了对其作为河流物种的地位的更复杂的定义
The position as a potamic or rhithronic species of Hydropsyche exocellata (Trichoptera: Hydropsychinae) was analysed with regard to: i) its metabolism temperature curve and the total amplitude of its respiratory metabolism between 5° and 25°C, ii) its distribution in some reaches of the Rhone River basin (France), and Hydropsychinae coexisting species in those reaches to assess its place in the stream continuum. Metabolism data indicated clearly that H. exocellata was a species adapted to the potamon, but distribution data did not confirm metabolism results. The absence of H. exocellata, for instance, from the lower and potamic reaches from the Rhone River itself, as well as its frequent coexistence with H. pellucidula, a well-established near-rhithronic species regarding metabolism, suggests a more complex definition of its position as a potamic species
