During the ____ stage, blow fly larvae are delicate and prone to desiccation.
A
first instar
B
second instar
C
third instar
D
fourth instar
Explanation: 

Detailed explanation-1: -Larvae: The blowfly has three instars of larvae. The first instar is approximately 5 mm long after 1.8 days, the second instar is approximately 10 mm long after 2.5 days, the third instar is approximately 17 mm long after 4-5 days.

Detailed explanation-2: -Blowfly larvae are known as maggots until the fifth stage of the life cycle when they become pupae. The larvae initially feed on fluid exuded from the body in which they live because the maggots have an enzyme that can break down proteins.

Detailed explanation-3: -Bloat stage A colour change is observed in the carcass flesh, along with the appearance of marbling. During the bloat stage the odor of putrefaction becomes noticeable. Blowflies remain present in great numbers during the bloat stage, and blowflies, flesh flies and muscids continue to lay eggs.

Detailed explanation-4: -3rd Stage Maggots (Pupae): In the third stage of maggots, now pupae, they fall to ground and no longer feed or move. Their exoskeleton hardens and turns from a light brown to a black color. Adult Blowfly: The adult blow fly emerges from the exoskeleton and can fly after only a few hours.
