The red-legged frog breeds in ephemeral ponds from January through March. Its relative, the bullfrog, breeds in permanent ponds from late March through May. There are two pre-mating isolation mechanism at play here,
1. Ecological isolation: The habitats are different, hence the individuals of both the species do not meet. Ephemeral ponds are temporary ponds that develop during rainy days, while the permanent ponds are full of water throughout the year.
2. Temporal isolation: The time of mating is different for both the species to avoid contact between the individuals of closely related species. Red-legged frogs mate in January to March slot and the bullfrog in the March to May slot.

Answer:
Blowfly adults looking for a place to lay their eggs
Explanation:
Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.
The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.
