The Scoop on a New Children’s Book about House Flies

November 11, 2015 / / 2 Comments

Usually we feature photographs of the Bug of the Week on Wednesdays, but this week for a change of pace we have a new children’s picture book about house flies. It is a nominee for a 2015 Cybils award in the Elementary/Middle Grade Nonfiction category.

The premise of I, Fly: The Buzz About Flies and How Awesome They Are by Bridget Heos and illustrated by Jennifer Plecas is that house flies deserve to be studied even though they aren’t as attractive or iconic as butterflies.

At first glance this book does not look like typical nonfiction. The illustrations are cartoons, complete with speech bubbles. The narrator is a stylized fly “speaking” in first person about his mom, brothers and sisters, as well as doing a bit of “trash-talking” about butterflies. Even the yucky/gross aspects are covered with a humorous touch.

Don’t let the fun facade fool you, however. The text is full of carefully organized and well-researched facts about house flies. Readers will learn that house flies go through complete metamorphosis like butterflies, but that their larvae and pupae look very different. Heos slips in facts about house fly flight, anatomy, other flies that are relatives (mosquito, blow fly and fruit fly), and even some problems with flies (they carry disease-causing bacteria). Is it true that house flies throw up on our food? Yes, but only solids and it is more like spitting up.

I, Fly will be highly appealing to children (of that certain age) who are enthralled with all things gross and disgusting. The lighthearted approach will make it palatable to parents, teachers and librarians, as well.

This book would pair well with the fictional picture book Diary of a Fly by Doreen Cronin and illustrated by Harry Bliss. In fact, the pair could be used to compare nonfiction and fiction.

Bug of the Week: Early Instar Hornworm

November 4, 2015 / / 0 Comments

It isn’t unusual to find tobacco hornworm caterpillars on the datura plant.

What is unusual is to find one with such a long “horn.” It is likely that it recently hatched from an egg.

Probably most of you know that insects need to shed their exoskeleton or outer “skin” in order to grow (as well as the linings of the breathing tubes and parts of their digestive system). When an immature insect sheds its exoskeleton or molts, it is said to enter the next “instar.” The word instar is Latin and it means likeness or counterpart. The caterpillar above would be in its first instar.

Tobacco hornworm caterpillars generally go through 5 instars, but that number can vary with environmental conditions.

Before it pupates, the tobacco hornworm caterpillar will leave the plant and look for a place to burrow into the soil, as shown in this time lapse video.

Before long an adult moth will emerge and the cycle will continue.

Why do you think the first instar caterpillar is “rearing up” with its head away from the plant? Any ideas?

Bug of the Week: A Mix of Leaf-Footed Bugs

October 28, 2015 / / 2 Comments

Often when you see an insect, only one life stage is present.

That wasn’t true with the leaf-footed bugs we spotted today. There’s an adult on the right. It has full wings and big flaps on its hind legs, which gives it the name “leaf-footed bug.” On the left is a large nymph with smaller flaps and stubby wing pads. So, what is the smaller orange insect?

Turns out that is a small leaf-footed bug nymph. Isn’t it amazing how different it looks from the adult. It doesn’t have flaps on its legs at all.

The adult looks like it is standing over the nymph and protecting it. A little research reveals that leaf-footed bugs are an example of insects that exhibit parental care. In fact, when scientists removed leaf-footed bug adults from their young and placed them on a nearby plant, the adult bugs flew back to the nymphs and stayed with them.

In case you were wondering, these leaf-footed bugs are feeding on the fruit of a datura or moonflower plant.

If you are interested in learning more, here’s a .pdf of a Scientific American article about parental care in insects (hosted at Colorado). Very cool!
