Description: SCP-2598 is a Large Yellow Underwing moth (Noctua pronuba) wearing a small helmet. Apart from this, and its behavior, no other anomalous characteristics are discernible. SCP-2598 is able to communicate with humans by colliding with their heads in a pattern consistent with American Morse Code. While SCP-2598 is apparently able to hear and understand English, it is only able to communicate a return message in this manner.
