Which type of flies does not lay eggs at night?

Blowflies are known for their diurnal behavior, which means they are active during the day when they seek out carrion on which to lay their eggs. This is largely due to their dependence on light for navigation and their attraction to the scents emitted from decomposing organic matter, which are more detectable in daylight.

Flesh flies, houseflies, and coffin flies, on the other hand, can exhibit different activity patterns and may lay eggs at various times of the day or night. Understanding the behavior of these insects is crucial in forensic science, particularly in estimating post-mortem intervals in death investigations, as larval development stages can provide significant insights based on the species of fly and their activity patterns.
