Hyalella azteca is a 1/8- to 1/4-inch-long crustacean commonly found in lakes, ponds, and streams throughout North America. They are an important link in the aquatic food chain and a food source for several predators, including fish and various invertebrates.

Pesticides such as pyrethroids from residential runoff have recently been discovered to kill Hyalella. Low numbers of aquatic organisms, like Hyalella and Ceriodaphnia, is an indication of poor water quality.
