Nothochrysa capitata (Fabricius, 1793), CONIOPTERYGIDAE Panorpa cognata is een insect uit de orde van de schorpioenvliegen (Mecoptera), familie van de schorpioenvliegen (Panorpidae). Cunctochrysa (1:2) is represented by C. albolineata and seems not uncommon in our area. The abdomen is black and yellow striped with an orange extremity. The male is identified by the last thick segment before the tail, this is not conical and has a clear increase. The larvae are aquatic, feeding on freshwater sponges, hence their name and the adults come to light, often in numbers in suitable localities. 1869.
