Uenoid case-maker* (Family: Uenoidae)
Tolerance: moderate

* The following identification is a "best guess." The case includes several larger stones near the head-end. The first two images are of a specimen found in the upper watershed. The third was found lower in the watershed at Lewisville Park. This last specimen was found "floating" in the sample, without a case. Notice the yellow body and row of black hairs on the lower abdomen.

Note from author: Considerable effort has been made to be as accurate as possible in the identification of the organisms. While I am fairly confident of the ID (at least for the major taxon levels), I cannot guarantee complete accuracy. In particular, you will notice that some organisms are labeled with a (*). This indicates a probable classification based on general traits (shape, size and color) of the organism and location from which it was found. I do not possess the level of expertise nor did I conduct the kind of detailed inspection to provide a conclusive ID -- consider these efforts at classification as my "best guess" based on available information and, in some instance, outside assistance. (If you notice any errors or omissions, please contact me at the email address provided at the bottom of this page.)
