You know you’re a pathetic bug nerd when you’re watching a show about the first use of forensic entomology, and you stop paying attention to the narrator because you’re too distracted by the fact that while the narrator is saying, “….human skulls covered with maggots…” the re-enactment is showing skulls covered with fake blood and the larvae of  Tenebrio molitor, which, being the larvae of a darkling beetle and being commonly referred to as “mealworms” are neither maggots nor a species typically found on decomposing flesh. It is, however, a species that is very readily available in bulk, since it is raised commercially for pet food and fishing bait, which is why it’s often used for television and movies when large numbers of squirmy, icky bugs are required.
