Note the fluid moving at 16 seconds and when feeding on a dragonfly nymph at 52 seconds. Larvae feed by injecting digestive juices into the body of their prey and sucking up the digested contents through their tubular mandibles. They leave the water (after molting 3 times) and dig or build a cell in mud. The adults emerge and head back to the water 1-2 weeks later. Filmed from December 31, 2016 - January 15, 2017 - yes, they are active during the winter! From a farm pond in the Missouri Ozarks, USA. Anyone is welcome to key these larvae. I don't have the resources or experience to do it.
