What distinct life stages do insects undergo that are relevant to forensic investigations?

• A. Eggs, larvae, pupae, and adults
• B. Fertilized, embryonic, mature, and aged
• C. Caterpillar, chrysalis, moth, and beetle
• D. Infant, juvenile, mature, and senescent

Answer: (A)

Insects undergo a distinct life cycle known as metamorphosis, which consists of four key stages: eggs, larvae, pupae, and adults. Each of these stages has unique characteristics and time frames that can be crucial for forensic investigations. In the egg stage, the beginnings of development occur, and the time taken for eggs to hatch can provide important information about the timeline of an event. The larval stage, often referred to as the maggot phase in forensics, is critical as it is during this time that the larvae feed and grow. Forensic entomologists often rely on the size and development of these larvae to estimate the postmortem interval, as different species have specific growth rates under various environmental conditions. The pupal stage marks the transition from larva to adult, wherein the insect undergoes a significant transformation. Understanding how long an insect typically remains in the pupal stage can also aid in estimating the time of death. Finally, the adult stage is where the insects emerge fully formed and ready to reproduce. The presence and type of adult insects can indicate the length of time since death and other environmental factors that may have influenced decomposition. This complete cycle from egg to adult provides essential data points for forensic investigations, making it critical to
