The PMI (Post-Mortem Interval) for remains of a body enclosed in a plastic bag could best be estimated by **blowfly maggot counts**.

Blowflies are typically one of the first insects to arrive at a decomposing body, and their life cycle can provide valuable information about the time since death. While other methods such as studying trauma, skeletal evidence, and chemical analysis are useful in forensic investigations, the presence and development of blowfly larvae can give a more immediate estimation of the time since death, especially in cases where the body is concealed or in environments that may limit the effects of environmental decomposition factors.

Forensic-anthropology methods are used to study **modern graves**.

While forensic anthropology primarily focuses on examining human skeletal remains and associated artifacts to provide information about identity, cause of death, and circumstances surrounding modern deaths — often in legal contexts — archaeologists typically study ancient societies and their remnants, including ancient peoples' activities and cultures.

The first insects to be attracted to a corpse are the **blowfly adults looking for a place to lay their eggs**.

Blowflies are typically among the first to arrive at a decaying carcass, and the adult females lay their eggs on the body. These eggs then hatch into larvae (maggots) which contribute to the decomposition process.

The presence of vast numbers of maggots or pupae can be used to determine PMI because the succession of insects on a corpse is **predictable based on temperature**.

In forensic entomology, the development stages of insects, particularly blowflies, are influenced by environmental factors such as temperature. This allows forensic experts to estimate the time since death by analyzing the life cycle of the insects present on the remains.

The stage that best matches the description "Blowflies come and lay eggs on a corpse in open air" is **Day 1**.

Blowflies are typically the first insects to arrive at a decaying corpse, often within hours of death, and they lay their eggs soon after they arrive.
