Bug of the Week: Z the Fruit Fly

Ever wondered where something like “Bug of the Week” might lead? Sure it is fun, but can anything really useful come out of checking the insects in your back yard once a week? It turns out some very cool things can result from regular bug watching.

A few weeks ago when I was looking at the fruit flies in my yard, I found something I didn’t recognize. I sent it to a friend of mine at the University of Arizona to identify.
Take a look:

When I looked through my camera lens I saw this fruit fly with incredible white stripes that almost glow florescent, they are so bright.

My friend identified it as Zaprionus indianus, a fruit fly native to Africa, the Middle East, southern Europe and southern Asia.  This species was first found in the Americas in 1998 when it was reported from São Paulo, Brazil. It just arrived in Arizona within the last year or so. I call it “Z” because of the genus name and its fancy zebra stripes.

Here is a photo of Z under a powerful microscope:

I’ll be keeping a good eye on Z to find out what it likes to eat and how many are around. Right now it hangs out with the other fruit flies in the compost heap.

You never know when you might meet some new insect neighbors, if you just go out and look.

Bathtub Buoyancy 2: Paper Boat Floating Results

Are you ready for the results of the floating experiment for paper boats? (See “How Long Can a Paper Boat Float?” post)

A friend did this test, although she didn’t say what kind of boats or for how long. Our friend found “the one that lasted the longest was made from a wax paper sandwich bag.” Thanks M!

We folded 5 different boats out of various papers and then floated them in plastic bins filled with water. We left the boats in the bins outside for 24 hours.

Here are our results:

1. We made a newspaper boat, inspired by the “Curious George” book. How did it do?

The newspaper boat was getting soggy after about ten minutes and went down in half an hour.

2. Paper boat number two was a piece of computer/laser printer paper rescued from the trash.

How did it do?

It actually sunk right before the newspaper boat, although in the past I have had computer paper boats make it over night. Perhaps it was folded more tightly than this one or the paper was a different brand.

3. Number three was a small piece of bubble gum wrapper.

It floated 24 hours. Go, gum wrapper, go.

4. The fourth paper boat was a folded piece of yellow legal paper.

It was still going strong after 24 hours, although its bottom was a bit soggy.

5. Paper boat number five was also made of yellow legal paper, but it had a fancy wing design.

It was also floating after 24 hours.

We didn’t try any coatings or finishes, which would probably have allowed our boats to float even longer.

Edit: See our final results

If you want to be inspired to make a paper boat, try reading:

by H.A. and Margret Rey
In this book, Curious George makes a paper boat regatta. The instructions for folding the boats are included.

The Amazing Book of Paper Boats: 18 Boats to Fold and Float by Jerry Roberts, Melcher Media, Willy Bullock, Melcher Media

For more advanced boat builders (although you wouldn’t want to float them when you are finished). Assembly trick: investigate some of the tape adhesives used for scrapbooking.

Bug of the Week: Another Lacewing Larva

Lacewings are pretty common in Arizona and I found another lacewing larva last week. (Check previous posts about the life cycle of lacewings).

This lacewing was walking on the silk cocoon of a moth. You can just see the outline of the pale green moth pupa under the white strands of silk of the cocoon. I think the lacewing larva was trying to get inside, without much luck.

See its long jaws? I think it might be the larva of a brown lacewing, rather than a green lacewing, because it looks a bit different. The brown lacewing adult has brown wings, hence the name.  They aren’t as fragile-looking as the green lacewing and we tend to find them more often in the colder months.
