Insects Book and Insect Senses Activity for Kids

For STEM Friday we are sharing a Smithsonian Little Explorer nonfiction title:  Insects (Little Scientist) by Martha E. H. Rustad.

Young children are often fascinated by insects and this book will give them a good foundation in the basics of insect science. In addition to explaining metamorphosis and insect senses, it covers eight main insect groups from ants to grasshoppers. Each section is a two-page spread with bright color photographs throughout. Some of the photographs are edge to edge, giving a feeling that you are actually seeing the scene first hand.

In the back are suggestions for thinking more deeply about insects, as well as a glossary, book recommendations for further reading, and a portal to Internet Sites through FactHound.

Insects will thrill budding entomologists. It is also a useful resource for libraries and classrooms.

Let’s celebrate the book with an activity.

Related Activity:  Exploring Insect Senses

The following are public domain photographs taken by the USGS Bee Inventory and Monitoring Lab.  Name links will take you to the image in Flickr. Note:  For the squeamish, there are a few photographs of dead birds in their photostream (preserved specimens).

Animals need to be able to detect or sense information about their environments in order to survive.

1. Brainstorm about human senses.

Read a book about human senses, such as My Five Senses by Aliki (as seen read in this video).

Ask the children about what senses humans have and why they are important (like avoiding danger or finding safe food to eat).

(Extension:  You are likely to have been taught in school, as in the book, that humans have five senses. This is a simplification. Think about other senses we have, such as the ability to sense pain or the ability to tell which way is up in relation to gravity. We can also tell when our stomach is full via stretch receptors. Some scientists think we may have up to 20 senses!  How Stuff Works has more about this.)

2. Find out about insect senses.

Insects have senses as well, but theirs don’t look the same and work in different ways than ours do.

Can you believe that mosquitoes hear with their antennae and that crickets hear with tympana (strips of membrane stretched tight) found on their legs?

Many insects can detect chemical odors via their antennae, which work in a similar way to how our noses detect smells.

Look at the photographs below and try to find the parts the insects are using to see, hear, smell, taste and touch things around them.

Parts to look for:

  • Antennae
  • Compound Eyes
  • Ocelli (simple eyes)
  • Mouthparts

Bonus:  see if you can spot any special sensory hairs.

Once you have examined these insect photographs closely, go to the answer post for labelled photographs and more information.

Isn’t it amazing that even though they look and work in different ways, insects have senses just like we do?

Bug of the Week: Stilt-legged Flies

A teacher friend last week suggested he could show images from Bug of the Week to his class via a SmartBoard and ask students for insights into what they see (Great idea, Jeff!)

stiltlegged-fly-Rainieria antennaepes-34This insect (from the archives and from western New York state) would be perfect for that kind of student exploration.

First, you might want to ask what kind of insect it is. Is it a wasp? An ant? Or a fly?

Stiltlegged-fly-Rainieria-antennaepes-23

Here’s a closer view. Why does this insect have red eyes? Why do you think it has such long legs? What are those orange marks on its legs?

In case you don’t recognize it, the insect above is a stilt-legged fly, Rainieria antennaepes. Most experts think it is a parasitoid wasp mimic (like this one), but some of its relatives are ant mimics.

Although it is not readily apparent in these photographs, the tarsi or “feet” of the front legs are white. The insect holds its front legs out in front of itself and waves them around like antennae. The species name antennaepes means antenna foot, referring to this behavior.

You can see a fly of a closely-related species waving its front legs in this video. Keep alert for one scene that shows what the adult flies feed on. Look closely at the front of the head where the sponging mouthparts are found.

Did you see it? The adult flies feed on bird droppings and similar wastes.

Isn’t that an interesting fly?

Bug of the Week: Green Lacewing Life Cycle

Today’s find is the egg of a green lacewing.

lacewing-egg-croppedLacewing eggs are pretty easy to identify because they are on the end of a hair-like stalk.

A few months ago I found a good example of a lacewing cocoon. Time to make an green lacewing life cycle infographic!

lacewing-life-cycleInfographicGreen lacewings are considered to be beneficial insects because the larvae are predators of scales, whiteflies, aphids, small caterpillars and other potentially pesty insects.

The pupa stage forms within a cocoon that is usually hidden on a branch or twig. The lacewing cocoon may be mistaken for a spider egg case because the silk resembles spider web.

The adults are light green with delicate wings and golden eyes. If disturbed from a leaf they will fly during the day, but are more active at night. The females generally lay their eggs at night.

We’ll probably be seeing more and more of these as our weather warms and the wildflowers start to bloom. Just a few more weeks.
