Kids Get Crafty

Amy Wells —  May 21, 2013 — 1 Comment

My 3-year-old son and I have enjoyed many seasons of Little Diggers. We have learned new things together and have had  a lot of fun with the projects—but our favorite project so far this year was with insects. We got up close and personal with ants, butterflies, grasshoppers, and ladybugs. The instructor set up habitats in mesh containers where we could look at each group of insects with magnifying glasses and two-way viewers—the same tools real scientists use every day!

After looking at all the insects up close, we talked about all the different body parts an insect has, and why that makes an insect an insect and not a spider or another bug (even though they have a lot of the same body parts). All insects have three body parts (head, thorax, and abdomen), six legs, antennae, eyes—and sometimes wings! We remembered what the body parts were and where they go by building our own model insect. It was really easy—a fun and funny way to teach our little people about the different parts.

You can build your own model insect at home, too. Here’s what you’ll need:

  • An egg carton—Cut into strips of three eggs-worth. You can get four insect bodies out of one egg carton, so you can explore and make more than one kind of insect.
  • Coffee filters—Cut these each into six pieces for wings. You can see how to cut them from the photo of our completed insect below.
  • Pipe cleaners—Cut these into 3-inch pieces for legs.
  • Craft supplies to decorate and color your insect—Use feathers, googly eyes, crayons, gems, and tacky glue. Insects come in all shapes and sizes from simple black ants to very colorful, shimmery beetles. Have fun creating!

Use these materials to build your own insect.

As we built our insect and decided what it should look like, we talked about the different parts of our particular insect. We put antennae and one eye on the head, a feather and another eye on the thorax, and wings on the abdomen—and this was fine by me! While he was hesitant to put parts where they should go, he said “head,” “thorax,” and “abdomen” out loud as we built and talked about our insect. He was very proud of this final specimen.

Every class we go to uses different activities to explore a different theme. We’ve used play dough, enjoyed circle time with great books, gone on Garden walks, and let’s not forget our favorite activity, planting! (This time we planted some Mexican heather as part of the insect theme. Butterflies and bees love the nectar from the flowers of this plant.) We planted our heather at home and are waiting to see if we get visitors this summer.

Our finished project!

We can’t wait until the fall season of Little Diggers, but if you don’t want to wait, you can sign up for My First Camp for 3-year-olds, and enjoy more hands-on science, art, food, and gardening.

Signs of Emerald Ash Borer

Tom Tiddens —  January 4, 2013 — 3 Comments

It’s sad but true:

As I drive around the north suburbs, I am noticing many roadside trees with a spray-painted mark or a ribbon around the trunk. As an arborist, I know that these are ash trees marked for removal because of the emerald ash borer (EAB). The emerald ash borer is beginning to hit our area hard, and many municipalities are trying to stay one step ahead of this ash-tree-killing insect by proactively removing these doomed ashes.  

woodpecker_damage_3If you have an ash tree on your property you should be monitoring for this pest, as it is only a matter of time before the borer finds your tree. In winter, the easiest way to identify if your tree already has EAB is to look for woodpecker damage. From a distance, woodpecker damage looks like lighter colored patches on the trunk, as you can see in this picture.  Woodpeckers make these marks as they feed on the tasty (to them) borers that are just under the bark. Once you start seeing evidence of EAB activity, your tree will most likely suffer severe dieback within three years. There is an insecticide treatment that can save your tree, but treatments need to begin before your tree is infested.

What Are Those Bugs?!

Kathy J. —  October 25, 2012 — 1 Comment

PHOTO: Three boxelder bugs sunning themselves on the wood siding of the Garden's Learning Center.They’re all over the Learning Center and maybe around your house, too. They are boxelder bugs, and although they are a nuisance, they are harmless.

So while they are bugging us, let’s find some things to admire about them.

First let’s answer the question: Why are they all here right now?

It’s all about their life cycle. These insects spend their youth in the woods during summer, growing up flightless. In late summer/early fall, their wings develop and they can take flight, seeking a nice, cozy place to spend the winter. Can you blame them for wanting to come into our comfortable homes? OK, don’t answer that.

They belong to a group of insects commonly called “True Bugs.” Insects in this order are distinguished by their straw-like sucking mouth part, which they use to feed on the juices of plants. You see – they don’t have teeth, so they can’t bite you!PHOTO: this closeup of a boxelder bug has an arrow pointed to the red "V" on the bug's back where the forewings meet.

These insects also have two pairs of wings that cross in the back. The forewing is thicker than the bottom of the wing and this gives true bugs a distinctive “X” or inverted “V” on its back.

Now let’s talk about that beautiful red color! Watch one fly away and it will flash its sassy red abdomen. In nature, red coloring usually warns predators that this creature will taste bad. I was not able to confirm whether boxelder bugs taste bad or just mimic other bitter tasting bugs. Either way, I don’t recommend trying them yourself. And I must warn you that if you smash this bug on your wall or any fabric, that red color can stain.

While these insects are related to stink bugs, boxelder bugs do not have a bad odor. The bug I was holding in this photo must have been regretting this fact.

Wikipedia lists some other names for boxelder bugs, including “zug.” So when you see these creatures congregating on a sunny spot don’t say, “Ugh!” Say, “Zug!”
