Trivia

 * The Astrophage is designed and named after bacteriophages, which are real life viruses known for their uniquely insectoid and mechanical appearance.
 * An astrophage-like enemy was originally developed by a community member named L0st_M1ner while Calamity 1.4's Astral Infection expansion was being planned. A pet version of that enemy was added to the Calamity's Vanities fan mod, prior to this redesigned Astrophage pet being added to Calamity proper.
 * The name Astrophage roughly translates to "star eater".
