The Life Cycle of a Mealworm
The mealworm's life cycle can normally be anywhere from four months to a year. Each mealworm's lifespan can be different. Some can die way sooner than others just like humans.

The first stage of the mealworms life is basically an egg. The egg is very tiny the mealworm is in this stage from a range of 1-4 weeks.


The mealworm will stay in its larva stage for about 4-6 weeks. The larva stage is one of the beginning stages of the mealworm's life cycle. This was the stage our mealworms were in. The larva was very small, scaly, and had light brown skin.

The third stage of a mealworm's life is the pupa stage. This is the last part of molting in the mealworm's life cycle. This stage lasts about 1-3 weeks.

The final stage of the mealworm's life is the Adult stage where it becomes a beetle finally. This stage can last anywhere from 1-3 months.


Observations
All throughout the mealworm inquiry project we had to observe the mealworm and make observations. We had to look closely at how they looked and acted when we were first introduced to them.

When I first got my mealworms I was going to take home I first took some initial observations on how they looked and acted.

My first observations were:
They kept moving upward in their container.
They had 6 legs towards the front of their body.
They had no legs in the back.
They enjoyed digging in their oats.
Initial Questions
Why do mealworms shed skin?
They shed skin because they must molt in order to grow.

What is a mealworm's average life span?
They can live up to a few months.

What habitat do mealworms normally live in?
They live in a dark, cool, moist environment.

What animals eat mealworms?
Mice, rats, snakes, and birds are some animals that eat mealworms.

Why do mealworms like oatmeal?
They enjoy dry foods.

Hour number two= played dead
Hour number three= moving around the top
Hour number four=played dead
Hour number five=played dead
Hour number six=going towards bottom
Hour number seven= moving around the top
Hour number eight=no movement
Hour number nine= no movement
Hour number ten= no movement
Hour number eleven= top movement
Hour number twelve= no movement
This is a great video describing the life cycle of a mealworm. It shows transformations that the mealworm undergoes during the cycle!
This is a web page that is very useful to find information about the care that a mealworm needs to have!
