Location and Habitat
Location Accuracy (meters):
0-25
Habitat Type:
Riparian - Areas Along lake or stream
Habitat Type Notes:
Ephemeral stream corridor, Montezuma Canyon, with nearly perennial natural rheocrene spring (Sparke's Spring). Site has no surface water at time of survey, but soil is moist from subsurface water and recent rain. Riparian woodland dominated by a canopy of mixed oak, juniper, and sycamore. Stream channel dominated by seep willow, deer grass, and rushes. Substrate is primarily gravel covered with leaf litter with some larger dispersed rocks.

Observation
Observation Type:
With Flash Data
Number Observed:
2-10
genus:
bicellonycha
Species:
wickershamorum
Observation Notes:
Body length approx. 1 cm. Dull yellow margins and suture. Some individuals observed crawling in leaf litter (while not flashing). One individual preyed upon by an antlion during survey.

Flash Behavior
First Flash Time:
19:40
Last Flash Time:
20:45
First Flash Temp (F):
76.7
Last Flash Temp (F):
77.1
Flashes in Pattern:
1
Flash Color:
Yellow
Flash Pattern Period:
irregular
Flash Duration:
1
Flash Interval:
3-5
Male Height Zone:
Low (0-3 ft), Moderate (3-8 ft)
Flash Location:
Flashes occurred both during flight and while stationary. Generally, flashing was low to the ground or on the ground but occurred as high as ~8ft later in the night. Flashers in flight would at times, fly the length of the stream corridor and onto the upland. Stationary flashers were sometimes at tips of vegetation or on rocks.
Male Flash Behavior:
Flash pattern seemed irregular and inconsistent, perhaps due to predator species being abundant in the area. Survey ended before flashing completely ceased.
Female Flash Behavior:
n/a
