Bug of the Week: Amberwing Dragonfly Posing

Two years ago I caught a Mexican Amberwing dragonfly hovering over the water. I have wanted to get a photograph of one sitting still ever since.

I finally had a chance. It was perching at the top of a red bird of paradise.

It is a pretty small dragonfly, although there isn’t much here to give it scale.

Dragonflies are interesting because they vary a lot in color. Some amberwings have completely brown-gold wings whereas others have patches in clear wings like this one. Makes dragonfly identification quite tricky at times.

Arizona Dragonflies has a lovely series of photographs of Mexican amberwing dragonflies that show the variation in wing color.

It always amazes me to see dragonflies flying miles from water in the desert. It just goes to show how strong fliers they are.

This one was perching and then catching flying insects as they flew by.

Have you spotted any dragonflies this week?

Bug of the Week: Cacao Midge

We found our bug of the week today from an unusual source, a children’s picture book called No Monkeys, No Chocolate by Melissa Stewart, Allen Young and illustrated by Nicole Wong. no-monkeys-no-chocolate(For a full review, see our sister blog, Wrapped In Foil).

You may wonder what a book about chocolate and monkeys has to do with insects. It turns out that cocoa trees grown in open plantations don’t make as many seeds as trees grown under the canopy of the rainforest. When scientists began to tease out the reasons why, they found that cocoa flowers are pollinated by a small fly called the cacao midge. The flowers are highly complex, so not just any insect can do the job. The flowers are also not self-pollinated. That means our chocolate bars and hot chocolate are the direct result of the presence of a tiny fly.

What does this fly look like? I was able to find this video of Mark Moffett (the insect photographer equivalent of Indiana Jones) capturing a photograph of the elusive fly.

Now that we know about the cacao fly, I would say chocolate lovers will definitely want to do everything we can to preserve it!

Bug of the Week: Grasshopper Drawing

Do you remember last week when I wrote that the grasshopper in the photograph inspired me to want to draw it?

Well, I did:

grasshopper-drawing-growingUnfortunately it did not scan well. However, drawing it allowed me to really see a number of details I had previously missed.

For example, take a look at the hind (jumping) leg. The segment that would be our thigh is called the femur in insects. Do you see the circular area at the top where the femur connects to the tibia (the area that would be our knee)? It is white and looks like a flange in the photograph. I wondered what that was when I was drawing it.

Checking out how grasshopper legs work, I found the authors had called it “the lump” at first, but if you keep reading by hitting the next arrows at the bottom, you will find out it is called the semi-lunar process and it is important for jumping. Basically it forms part of a catapult that shoots the grasshopper forward.  I highly recommend taking a look at the website. There are some very cool physics are involved, and even animations to show the legs working.

Have you drawn anything this week? What did you discover?
