Predator-Prey: Who Eats Whom?

The way animals and plants behave is so complicated because it not only depends on climate, water availability, competition for resources, nutrients available, and disease presence but also having the patience and ability to study them close-up.

We’re going to build an eco-system where you’ll farm prey stock for the predators so you’ll be able to view their behavior. You’ll also get a chance to watch both of them feed, hatch, molt, and more! You’ll observe closely the two different organisms and learn all about the way they live, eat, and are eaten.

    Regarding our problem with dripping: we tried dental wax around the opening, and that did the trick!

    We’re having trouble keeping our small water canister from leaking. Instead of feeding along the string, it drips out the bottom. Any advice?

    They should make one that requires bulldog ants.

    Carolina Biological is one of the most popular places to get live species.

    Do you have any recommendations on where to purchase the mantis eggs online and also does it matter what type of mantis. I didn’t realize there were so many!

    There’s not a lot of “action” with a terrarium in terms of movement, but here are photos of completed projects using the terra aqua column:

    I don’t have any predators, but I do think the experiment will be fun!

  13. Michelle Stevens says:

    If you don’t have charcoal, what could you use instead?

    I had only tiny holes that were bigger than the preying mantis, and fruit flies also stayed in the container. You can put a fine mesh screen over the holes if you are concerned about it, though. Check hardware store for mesh cloth or use a couple of layers of cheesecloth.

    With a bottle brush? 🙂

  19. Yunhee Christian says:

    how do you clean the inside of the bottle? another thing, can’t they escape through the hole in the cap?

  20. Yunhee Christian says:

    how do you clean the inside of the bottle? just wondering.

    I think it is cool. But I hate bugs and spiders so I do not think I will do it. But I looks fun to see the lifecycle! it would be fun to mak it!
