How many days, max, does it take housefly eggs to hatch into larvae?
Correct Answer
A. 5
Explanation
Housefly eggs typically take around 24 hours to hatch into larvae. However, in optimal conditions with ideal temperature and humidity levels, the eggs can hatch even faster, within 24-48 hours. Therefore, it is possible for housefly eggs to hatch into larvae in as few as 5 days, making it the maximum time it takes for the eggs to develop into larvae.
2.
After hatching, how many inches are the larva?
Correct Answer
B. 0.3
Explanation
After hatching, the larva measures 0.3 inches in length.
3.
How many eyes do houseflies have?
Correct Answer
D. 3
Explanation
Houseflies have compound eyes, which are made up of thousands of tiny lenses called ommatidia. Each ommatidium contributes to a small part of the overall image, and the brain combines these images to form a complete picture. Houseflies have a total of about 6,000 ommatidia, which means they have around 12,000 individual photoreceptor cells. However, each ommatidium only contributes to a small portion of the visual field, so houseflies have a limited field of vision. Therefore, the correct answer is 3, as houseflies have three simple eyes or ocelli in addition to their compound eyes.
4.
Which kind of food do they eat?

Correct Answer
A. Temperature
Explanation
The development of hatchlings solely depends on temperature. This means that the growth and maturation of the hatchlings is directly influenced by the temperature of their environment. Temperature plays a crucial role in various biological processes, such as metabolism and enzyme activity, which are essential for the development of the hatchlings. The correct answer is Temperature.

7.
What's the lifespan of male houseflies?
Correct Answer
B. About 28 Days
Explanation
Male houseflies typically have a lifespan of about 28 days. Houseflies go through a complete metamorphosis, starting as eggs, then developing into larvae (maggots), and finally transforming into adult flies. The lifespan of a housefly can vary depending on factors such as temperature and availability of food. However, on average, male houseflies tend to live for approximately 28 days before dying. During this time, they play a role in pollination and can also be carriers of various diseases.

10.
How many legs do houseflies use for shock absorption when landing?
Correct Answer
A. 2
Explanation
Houseflies use only two legs for shock absorption when landing. This is because their front legs have specialized structures called pulvilli, which are adhesive pads that help them stick to surfaces. These pads also act as shock absorbers, allowing the flies to land smoothly without causing any damage or disturbance. The remaining four legs are used for walking and maintaining balance while on the ground.
