1 thought on “Observation: Photinus”

  1. Thanks for submitting this firefly observation! Based on the yellow flash color and the “dipper” description of the male flash pattern, it does seem like you observed a Photinus firefly, though the timing of flash pattern activity seems a bit later than would be typical for big dippers (Photinus pyralis).
