Rearing Facilities at UNT
Living Streams on the second floor are homes to stonefly nymphs and eggs year round


Stonefly eggs are containered in small glass vials with nitex screen lids and held at variable temperatures depending on the home stream conditions.  Daylight is also varied as needed.  Occasionally, antifungal treatments are necessary.


Nymph rearing chambers are styrofoam cups and lids with assorted substrates added.  Just a quick glance lets you know if an adult has emerged.


Adults are recorded while drumming within sound damped field-recording chambers.  A Sony minidisc recorder is used to record and encode to wav files on a computer.  Then analysis of drumming characters begins.
