Natural History


Both male and female Ebony Boghaunters usually perch flat, either on logs or the ground. Males often perch on sphagmun mats, making patrol flights low over bog pools


Small sphagnum pools in bogs and fens typically surrounded by woodlands


Mating usually happens away from the water. Females lay eggs into small bog pools by dipping abdomen into the water
