“B EHOLD and See 5 Worm Project. They found 215 worms!” —Diana
M etaMorphoSiS Growing up surrounded by adorable babies, puppies, and kittens, it is easy to forget that not all of God’s creatures start as small versions of adults. “Growing up” means something far different for insects. Beetles aren’t the only insects that go through complete or incomplete metamorphosis to reach adulthood. Dragonflies start their lives as swimmers! And butterflies andmothsmetamorphose fromegg,
Let’s put what we’ve learned to work.
Roll up Your Sleeves!
As a grub grows, it grows out of its skin! When the grub is ready to molt, or shed its skin, the mother feeds it again. Then, once the grub is finished growing, it pupates in the soil, and the parents’ work is done. In this resting pupal stage, the young beetle, or pupa, grows inside a cocoon covering rather like a sleeping bag, and then finally pops out as an adult beetle. When the adult beetle emerges, its transformation from egg to grub to pupa to adult is complete. (This process of going through different, changing forms to develop into an adult is called metamorphosis .) Now the new adult beetle begins looking for a dead animal of its own so it too can start a family.
Please remember to read all of the activities, right to the end of the chapter, even if you are assigned only one or two activities. Information contained in the activities is also instructional, and part of your lessons!

to larva, to pupa, to adult as well. In fact, it is almost worth raising tomatoes just to see if you can capture an overstuffed, green Tomato Hornworm caterpillar and witness it pupating into an adult moth. You can do the same thing with butterfly caterpillars, the larval stage of butterflies. You can plant
Remember that facilitation happens when two creatures of different species or groups have a working relationship that benefits both groups, like bees pollinating flowers.
Volcanoes and volcanic activity are often related to earthquakes. Volcanoes are formed when molten magma forces its way to the surface of the Earth, bursting a hole in the crust and flowing out to relieve the pressure. (Magma that spills out from volcanoes is called lava .) The weak parts of the crust give way, and the melted magma pours up and through the crust. As the magma cools, it builds up into tall cones over time. These tall cones are volcanic mountains, and are the typical volcanoes that erupt, or shoot out lava, every so often. What would you think if you were outside playing soccer in your backyard one day, and a volcano started to grow in the middle of your backyard? Such things have happened!
Think of two examples that you think might be facilitation, and then think up an experiment that would show if facilitation is at work in those circumstances. You do not need to perform the experiment.
Burying Beetles and Metamorphosis
One thing that we biologists discover very quickly is that many animals are very good parents. We know that birds are good mothers, and so are alligators and crocodiles, but insects can be outstanding parents as well!
Words to Know A grub is the worm-like,
pink or purple zinnias (butterflies are attracted to pink and purple), and capture caterpillars for pupating that way. Perhaps you would like to capture several kinds of caterpillars, keeping record of how long it took each to pupate, as different insects pupate on different timetables. By recording your findings, you become better prepared and more successful at raising critters through their developmental cycles. Do you see how recording your discoveries through notes and graphing can help in learning about the world around us?
I caught some beetles in a trap with some deadmice in it. These beetles are named burying beetles because they bury dead animals by digging a hole underneath them and then covering them with soil. Burying beetles are an excellent example of how even the smallest creatures take a lot of care in raising their children.
larval stage of an immature beetle. To pupate means to finish growing into an adult insect inside a cocoon- like structure. Metamorphosis is the process of going through different, changing forms to reach adulthood.

In Mexico, in 1943, a farmer was working in his fields when he noticed a steaming crack in the ground. In about a week, enough magma had poured out of that crack that a cone taller than a five- story building was created, right there in that poor farmer’s field! Within a year, the mountain had grown to more than 1,000 feet tall. With all the lava and ash burping out of the volcano, people in the area had to leave or get buried in ash and lava. But today, Mt. Paricutin is quiet. Now, the edges of the Earth’s plates are their weakest parts, and that’s where themost volcanoes are found. The edge of the Pacific
Both the mother and father beetle fly around an area looking for a dead mouse or squirrel to bury. They bury the dead animal to hide it from other animals like flies or skunks that might want to eat it. Once a dead mouse is found, the male and female beetles hollow out a small chamber in the soil by the mouse. Then the mother beetle lays her eggs in the chamber. Both the mother and father guard their nest.
The eggs hatch and grow into baby beetles, called grubs . The mother beetle brings the grubs to the food (the dead mouse) and then feeds her young grubs one at a time from her own mouth, just like a mother bird does.
