Bug of the Week: Different Crab Spider

Arizona has many different crab spiders.

We have colorful ones that hide in flowers.

We have gentle giants (Olios sp.).

This week we have a new (to us) crab spider.

It was small spot, a body and legs sunning on a car cover. At first glance, I thought it might be a tick.

A closer look shows it is a spider because it has two distinct body regions. Ticks are basically one oval body.

The forward-directed front legs indicate it is a crab spider.

In fact, it appears to be a ground crab spider, Xysticus sp. (Experts, please correct me).

It’s always fun to find something new.

Want to learn a few basics about how to identify spiders? See our previous post.

Or pick up a book from our growing list of children’s books about spiders at Science Books for Kids.

Bug of the Week: Lone Armyworm

While I was out for my morning walk, I found a caterpillar on the sidewalk.

The vibrant yellow lines on its back caught my eye. In the sun they look almost like gold leaf.

The larva was quite still, probably because it was in the 40s this morning.

It was still alive and began to crawl once I’d warmed it in my hand.

It is an armyworm, possibly a yellow-stiped armyworm given the yellow. If it completes its life cycle, it turn into an owlet moth (Family Noctuidae).

Armyworms get their name from the fact that they can migrate in large groups (armies). This one was a lone soldier.

STEM #Kidlit Seed Dispersal Book

Let’s explore another of the fantastic nonfiction children’s books that have been nominated for 2018 Cybils awards.

Although it may seem like a weird to be thinking of seeds and seedlings, in Arizona we plant our fall gardens this month. For that reason, A Seed is the Start by Melissa Stewart is timely.

Although the word “start” in the title and the pictures of sunflowers germinating on the cover suggests this books is about plant life cycles, with exception of a corn kernel germinating on pages 4-5 and an apple seed growing on pages 30-31, this book is about much more. In fact it is mainly about seed dispersal. Whether it is by wind, water, or animal taxi, author Melissa Stewart reveals the many, many ways seeds get around.

The color photographs are high-quality, as you would expect from National Geographic. From flying dandelion seeds to floating cottonwood seeds, the photographs will attract the reader’s attention.

A Seed is the Start is a lovely introduction to seeds and seed dispersal. Use it to sprout an interest in plants in a young reader today.

Activity Suggestions To Celebrate the Book:

1. Germinate a pumpkin seed.

Do you have some pumpkin seeds left over from Halloween or from Thanksgiving pies?

They can make an educational germination project.

Gather:
1. Pumpkin seeds (unsalted, raw)
2. Small containers – *see note
3. Potting soil

*Note:  Seeds may be started in almost any recycled container. Old milk cartons, newspaper pots, even empty egg shells can serve as containers. Put an opening in the bottom of the container for drainage and set it in a tray, and/or add some gravel or pebbles to cover the bottom.

Fill the containers with soil. Press one or two seed into the soil so covered slightly. Water until moist and keep watered regularly. Set in a sunny window.

If you prepare several sets, allow the children to carefully remove one or two of the seedlings from the soil over time. Discuss what they see, measure the stems and roots, and make drawings or take photographs to record the progress as the seed germinates and then the plant grows from day to day.

2. See our previous post for a fun quiz and seed dispersal activities.
