Location and Habitat

Location Accuracy (meters):

0-25

Habitat Type:

Woodland/Forest - Trees dominant, and in the over-story

Habitat Type Notes:

Dry calcareous soil east facing slope, they like the draws where water drains and dries up this time of year. They hover between 900-1000ft elevation they stay 4-5 feet off the ground and fly up to 10-20ft above ground. They definitely knew I was trying to get one for a photograph.

Elevation (meters):

295

Area Searched (hectares):

<1

Artificial Light Sources

Vehicles: No
Street Lights: No
Buildings: Yes
Only 2 lights low intensity but present

Artificial Light Types

Sky Glow (diffuse illumination in the sky): No
Light Trespass (light cast on surfaces beyond its intended target): No
Glare (bright light causing visual discomfort): No

Artificial Light Notes:

Very very dark with dense tree cover. Lots of chiggers and ticks here yay

Flash Pattern Period:

Flash Duration:

Flash Interval:

Male Height Zone:

Moderate (3-8 ft)

Flash Location:

All over the forest above the herbs inside the trees below the canopy. We have a steep hill they flash on too so when it’s pitch black it’s hard to tell if they’re higher in the trees or just higher elevation (more likely).

Male Flash Behavior:

Quick and short and fast very hard to catch for observation and they evaded capture multiple times.

Female Flash Behavior:

Didn’t even know they flashed hmm.

1 thought on “Observation: Photuris frontalis”

  1. Thanks for this observation of snappy single sync (Photuris frontalis)!

    Because of some changes we’ve made to the digital data form, I had to slightly modify some of your answers while verifying this observation. Below are your original answers:

    First Flash Temp (F): ~70-80
    Last Flash Temp (F): ~60-70

    Flash Pattern Period: <1 second
    Flash Duration: <1
    Flash Interval: 2 seconds (guess)

    Note that a the flash pattern measurements for a typical P. frontalis flash pattern would look something like this (though at a warmer temperature than your observation):

    Flash pattern period= 1 second
    Flash duration= 0.1 seconds
    Flash interval= 0.9 seconds

    We've added a flash pattern diagram to the digital form, which hopefully will make things less confusing!
