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.
