Forensic Entomology: Insect Succession & PMI Simulator

Interactive forensic entomology simulator: watch flies, larvae and beetles colonize remains in successive waves after death, then use their presence or absence to estimate the post-mortem interval, with ambient temperature scaling development speed.

Forensic entomologists estimate how long someone has been dead by reading the insects present at a scene: different species arrive, feed and depart in a predictable order as remains pass through successive stages, and each species' own development speeds up or slows down with ambient temperature. This simulator drives an abstract site marker through that timeline — blow and flesh flies first, then larval waves, then predatory and hide beetles — and lets you either watch the clock run forward or try to work backward from an unknown scene to an estimated post-mortem interval, the same reasoning used in real casework.

⚙ Under the hood

Watch flies, larvae and beetles colonize an abstract scene marker in successive waves after death, driven by a simplified accumulated-degree-hour model, then switch to reverse mode and estimate the post-mortem interval from which species are present or absent.
