Hi there! Let’s dive into a fun mystery about flies. Imagine this: you’re out fishing on a big lake with your family, and suddenly, a bunch of flies appear out of nowhere! Where did they come from? It’s a puzzle that has been on my mind for years.
Now, let’s talk about another fly mystery. Have you ever noticed flies buzzing around your trash can? It’s like they just appear overnight! Here’s what might happen: it’s a hot summer day, and you notice the trash can smells a bit. You decide to throw away a banana peel, and when you open the lid, a swarm of flies flies out! How did they get there?
Let’s investigate! If you stayed up all night watching the trash can, you might see something interesting. At first, there are no flies, but you notice some dark, oval-shaped things in the trash. After a while, these dark things crack open, and out come the flies! But how did those dark things get there?
Let’s go back in time a few days. You see some tiny, wiggly creatures in the trash. Over time, these creatures grow bigger and change color, turning into those dark things. Eventually, they become flies. But where did the wiggly creatures come from?
Going back even further, you see a fly land in the trash and leave behind a pile of tiny white things. These tiny white things don’t move at first, but soon they split open, and out come the wiggly creatures!
So, here’s the story: a fly lays tiny white eggs in the trash. These eggs hatch into wiggly creatures called larvae. The larvae grow and turn into dark things called pupae. Inside the pupae, they transform into adult flies. This whole process is called metamorphosis, just like how caterpillars turn into butterflies!
Isn’t it amazing how flies go through such big changes in a short time? Nature is full of surprises, and there’s so much to learn if we take a closer look. Whether it’s in the trash or in a garden, living things are always growing and changing around us.
Thanks for joining this mystery adventure! Remember, there are mysteries everywhere, so stay curious and keep exploring the world around you.
Fly Life Cycle Observation: Create a simple observation journal. Find a safe spot outside where you might see flies, like near a garden or a compost bin. Over a week, observe and draw what you see each day. Can you spot any eggs, larvae, or pupae? Write down your observations and share them with your class.
Metamorphosis Role Play: With your friends or family, act out the life cycle of a fly. One person can be the fly laying eggs, another can be the larvae, and another can be the pupae. Use blankets or sheets to transform into each stage. How does it feel to change from one stage to another?
Question Time: Think about why flies are important in nature. Discuss with your class or family: What would happen if there were no flies? How do they help other animals and plants? Write down your thoughts and share them with others.
Sure! Here’s a sanitized version of the transcript:

Hi, it’s Jay. I want to share a mystery that I’ve wondered about for years. When I was a kid, I went fishing with my dad and grandpa. We were out on Lake Michigan with nothing but water all around when suddenly, flies swarmed our boat. These were the kind of flies that usually buzz around trash cans. We had no idea where they came from, and it’s still a mystery to me.
Someone named Caleb has another mystery about flies. Let’s give Caleb a call now.
Hi, Caleb. I have a question for you. Why do flies just appear in the trash can?
That’s a great question and a great mystery. I’ll call it the case of the overnight flies. Ready, detectives? It’s another hot summer day. The sun beats down on the kitchen trash, and you get a whiff. Better empty it soon. But first, breakfast. You grab a banana and go to throw away the peel. But when you lift the trash can lid, a swarm of house flies comes buzzing out. Your whole family is confused. No one saw any flies earlier. The grownups are certain the trash can was closed when they went to bed and when they got up this morning. But if the trash was closed, how did the flies get inside? Did they just appear overnight?
I’m curious what you think happened. How did flies appear inside a closed trash can? Now, it would be a good time to pause the video and discuss.
Okay, are you ready? I’m not sure how you answered, but maybe you thought if you stayed up all night watching the trash can, you could have seen the fly sneak inside. You’re on the right track. Let’s take a peek inside. No flies yet, but there is something strange in the trash. These dark, oval-shaped things might be a clue. Hours go by, still no flies, but then you notice this. One of the dark things has cracked open, and something is coming out. What is that? It’s hard to tell at first, but eventually, they all crack open, and you see flies. Whoa, the house flies you saw in the morning came from those dark things, but how did the dark things get in the trash?
Let’s go back in time a few days and check out the trash again. No flies and no dark things, but I see something moving. Here’s a closer look. It’s these little wiggly creatures. Another clue. Over several days, the wiggly creatures grow bigger. Then they stop moving and start changing color. Wait, does that look familiar? They turned into those dark things. So the house flies came from the dark things, and the dark things used to be wiggly creatures. But how did the wiggly creatures get in the trash?
Let’s go back in time again, a few more days. Uh-oh, someone left the trash can open, and a house fly is landing inside. Is that one of the flies you saw at breakfast? No, it’s flying away. I guess not, but it did leave behind a clue: this pile of tiny white things. Weird. The tiny white things don’t move, and not much happens for hours, but then they split open, and these wiggle out. Hey, it’s the wiggly creatures.
So the house flies came from the dark things, the dark things used to be wiggly creatures, and the wiggly creatures came from the tiny white things. We just saw how the white things got in the trash. A fly put them there. We’ve been going back in time, but now let’s put these clues in order. The mystery actually started over a week ago when a house fly visited the trash. It left behind a pile of tiny white things. Next, wiggly creatures came from the tiny white things. Then the wiggly creatures grew and changed into dark things. And finally, flies came out of the dark things and flew around when you opened the trash at breakfast.
I think we’ve solved the mystery. The flies didn’t just appear in the trash overnight. They were already inside for over a week, starting at those tiny white things. And maybe you can guess what those are. They’re fly eggs. House flies lay their eggs in places with plenty of food for their babies. They love mushy, rotten things, so our trash is perfect. Those wiggly creatures that hatch from the eggs are baby house flies. Another name for them is larva. You probably noticed that they don’t look anything like adult house flies.
So how do they go from these wiggly creatures to having wings and legs? Well, remember when the larva turned into that dark thing? At that stage, it isn’t a baby or an adult. Instead, scientists call it a pupa. Its body makes a hard shell. Inside, it goes through a huge change, then comes out as an adult. All these changes the house flies go through after they hatch, from larva to pupa to adult, are a process called metamorphosis. If that sounds familiar, it’s because some other animals also go through metamorphosis, like butterflies. We have a lesson about it if you’re curious to find out more.
So it turns out those house flies went through the entire process of metamorphosis: starting with hatching from an egg to a larva, to a pupa, to adult in less time than it took to empty the trash. That’s amazing! Animals and plants are living out their lives all around us. Some change so fast and some change so slow that you might not even notice. By taking time to look closely at places you normally ignore, you may uncover clues to how living things grow and change, even in the trash.
That’s all for this week’s question. Thanks, Caleb, for asking it. Now for the next episode, we reached into our question jar and picked out three questions sent into us that we’re thinking about answering next. When this video’s done playing, you’ll get to vote on one. You can choose from: how do snow globes work? Could a kid win a race against a penguin? Or who invented mittens? So submit your vote when the video is over. We want to hear from all of you watching. There are mysteries all around us. Stay curious and see you next week.
