Giant Casemaker Caddisfly Larvae - 3 cases - feeding, moving, and aggressing (Ptilostomis)

I'm not sure why these larvae were aggressive toward each other. As I understand it, they do not have the capacity to kill prey of their own size. They typically engulf small prey or shred plants. I did observe one feeding on the carcass of a dead Caddisfly larva (not shown-too gross). I don't know what killed it and couldn't find an empty case. Giant Caddisfly larvae are distinguished by conspicuous dark stripes on a yellow head and thorax. They have a sharp horn on the bottom of the thorax segment one, which can be seen in this video. The last clip is in slow motion. Filmed in the Missouri Ozarks, USA, from a farm pond, March 5-6, 2017.
