Bug of the Week: November Butterflies and Moths

Here it is the end of November already and we still are seeing caterpillars out and about.

There’s silk, holes and frass on some of the hollyhock leaves.

Those belong to the painted lady butterfly caterpillars, Vanessa cardui. 

Painted lady caterpillars vary a lot in color. This one may be lighter because it is a color variation or maybe because it just molted.

They feed on a range of plants, from thistles to sunflowers, but painted lady caterpillars always have a patch of silk around them.

The adult butterflies migrate this time of year. We often see them feeding on lantana flowers. You can see adult butterflies in this post from November 2008.

Once I finished taking photographs of those, over on the Texas yellow bells, Tecoma stans variety ‘Orange Jubilee,’ I found another sizable caterpillar feeding.

This is a rustic sphinx caterpillar, Manduca rustica. In the past we’ve found them on desert willow and cats claw vine. (You can see an adult rustic sphinx moth in this previous post from the beginning of November in 2014.) They are common throughout the southern parts of North America.

Although it looks a bit lethargic above, it was still able to crawl around.

Actually, it was nice that it was a bit slow. I could zoom in on some of the details.

For example, in this close up of the head, you can see the caterpillar’s eye as the black dot right above it’s black front leg.

At the other end is the spiky tail spine.

Sphinx moth caterpillars often have a “tail,” which is what gives them the common name hornworm.

Caterpillars of painted lady butterflies and rustic sphinx moths in the same week. How cool is that?

Question About Science Experiment Kits for Kids

This week I received a question from a grandmother who wanted to find a hands-on science/STEM kit for her grandchild and wondered if I have any suggestions.

First of all, kudos to you grandma! You have a lucky grandchild!

A few recommendations for deciding on a kit:

  1. Pay attention to the child’s interests. Although they might not be able to articulate them clearly, children are individuals who have particular questions about how the world works and are often eager to investigate them. What does the child gravitate towards? Does he or she like trees, cooking, building things, or wonder how the human body works? Look for kits that feed the child’s passions.
  2. Pick kits that allow for some open-ended exploration, if possible.
  3. Try to find kits that can be used more than once, so the child can build on their learning by revisiting the experiments.

Some examples of commercial kits (Affiliate links go to Amazon):

Scientific Explorer My First Mind Blowing Science Kit

Appropriate for ages six and up, with adult supervision. Comes with supplies for 11 projects/experiments. (Check the video for a better idea of what is included.)

The Magic School Bus – Chemistry Lab

This one is probably for a bit older kids with good manual dexterity. The Magic School Bus kits are well-tested. Some of the experiments require common household items not found in the kit, such as vinegar, salt, pieces of banana, lemon juice, etc. Fun!

Our Family Favorites:

When he was younger, my son enjoyed the physical sciences.

Ben Franklin Toys Geology Lab Pad Science Kit

We found a kit like this one at a yard sale and used it on and off for years.

Snap Circuits SC-300 Electronics Discovery Kit

Be prepared to have to buy stock in companies that sell batteries, but these were favorites that got used year after year for different projects.

Build your own science kit suggestions:

Maybe not for gift giving, but you can also assemble your own science kits (links go to previous posts):

For Educators:

Because I often work with groups of children, I found the classroom kits at Steve Spangler Science helpful. They tend to have a lot of “Wow” factor, which might entice the more reluctant scientists.

Homeschooling High Schoolers?

We were pleased with the science kits from The Home Scientist, but they really are for teens/young adults. You can see how we used the honors chemistry one at this blog.

The bottom line is that no matter what kit you pick, providing some hands-on science is the right choice.

Do you have any suggestions for favorite science kits for children?

Bug of the Week: Sunflower Grasshopper

As I pointed out in one of my other blogs, I recently went to a u-pick farm. But instead of vegetables, I brought home photographs.

The sunflowers were glorious.

But of course, I spotted the grasshopper.

Wait, why does it have its left antenna down? In the previous photograph the antennae were up.

Oh. It’s walking forward. Where is it going?

Perhaps it’s going to continue snacking on the sunflower petals, because that seems to be where its left antenna is aimed.

Who knew grasshoppers used their antennae for GPS?
