How Dragonflies Are Able to be Such Good Hunters

I am linking to a detailed explanation of how dragonflies are able to detect and then intercept other flying insects.  Researchers at Howard Hughes Research Institute installed tiny reflectors on dragonflies to track their body movements while hunting.  Those reflectors were then followed by special cameras that send that tracking data to computers for analysis.  They found that dragonflies are good hunters because of their ability to anticipate the movements of their prey and calculate accurate interception routes.  I found it interesting that dragonflies approach their targets from below to avoid detection.  Jet fighter pilots sometimes use that same technique.  Dragonfly in flightThese behaviors are far more complex than expected in an invertebrate and have implications for the study of human behavior.

The Amazing Flight of the Butterfly

Have you ever tried to watch a butterfly fly? It is very difficult to do.  Even the swallowtail, one of the slowest fliers, still flaps its wings in a figure eight pattern five times a second. That’s 300 times a minute!  Only by using photography and slow motion video are we able to watch what is really happening.

Flight is achieved via muscles connecting the wings to the thorax.    The muscles are tiny yet they can propel some Monarch butterflies on a migration of over 3,000 miles!    That is pretty amazing to me.

Look at the King Swallowtail Butterfly in the background of this photo. You can see that there are really two sets of wings, upper and lower, each capable of moving independently. That wing design gives the butterfly the ability to hover or change direction very quickly. The King Swallowtail in the foreground is at rest appearing only to have a single pair of wings.  Researchers have found that butterflies in flight make hundreds of tiny wing adjustments each minute.  They do this to compensate for wind currents and the turbulence their own wings create.  They are complicated flying machines.

This ultra-slow motion video of butterfly flight reveals the figure eight pattern we can’t see in regular speed.

Our butterfly season is nearly over here in Texas.  The Monarchs are still moving through  on their migration, and we have a few Gulf Fritillaries and Swallowtails coming through.

Clearly this is not a bug!

Hummingbird at flowerThere is a lot more to see in a garden or field than just plants.  Flowers are nature’s way of attracting a wide variety of creatures.  Many plants need wildlife to help with pollination. A flower or vegetable garden or a field of blooming weeds is full of life.  Some come directly to feed on nectar or collect pollen such as bees, butterflies and hummingbirds.  Others, like spiders, wasps, assassin bugs and praying mantis, are attracted to areas with flowers because the bugs they eat are in the plants.  Then, larger animals such as lizards and birds are attracted to the area because of the variety of insects they can find there.

Hummingbirds are a special sight. They are fun to watch at a hummingbird feeder, but watching them feed at flowers is more fun to me.  This little female Ruby-throat Hummingbird checked out every bloom in the garden. I was able to catch a picture of her feeding at the aptly named Hummingbird flower yesterday.  She seems to prefer Hibiscus flowers too.

Some butterflies like specific flowers.  The Monarch butterfly requires the Butterfly Weed, also known as Milkweed, to lay eggs.

The Monarch larvae or caterpillars feed almost exclusively on Milkweed as they grow and prepare to undergo metamorphosis into a butterfly.  Other butterfly species have their preferred plants too.  When you think about it, that helps reduce the new caterpillars’ competition for the same plants after the butterfly eggs hatch.   Caterpillars have to eat a lot to grow and turn into a butterfly!

I have a wide variety of flowers in my back yard to hopefully attract different types of wildlife. It works beautifully most of the time.  I have discovered that something must be missing though.  A beautiful Tiger Swallowtail Butterfly passes through the yard several times a day without stopping. They like daisies. I have a daisy plant in a pot.  Perhaps they require more than one pot of daisies to make it worthwhile to stop and feed?

A great place to watch for butterflies, insects and other animals attracted by flowers is at a garden center. The large concentration of flowering plants attracts a lot of attention from insects. And it is free to walk around! Some of the pictures for There’s a Bug in my Blossom were taken at garden centers.

We can enjoy all that nature has to offer whether in our own yard, at the park or a garden center.  We just need to get out and observe.  And yes, sometimes flowers attract all sorts of wildlife!

Endangered cricket rediscovered by insect expert’s 7 year old son..

This story about the endangered Scaly Crickets on the beaches at Pembrookshire in the United Kingdom is a lot of fun. I believe kids have an advantage when it comes to seeing things.  Adults tend to take a broader view.  I know I do.  Kids look at a scene and can break it down into segments.  And within those segments they can see details that we adults miss.  I’m trying to regain that skill now as an adult. But I find that I still miss a lot until I take a photo and zoom in on it with the computer. Then I see all that I missed in the initial scan. I could attribute missing details to older eyes, but I believe there is more to it than that.

After raising four of my own, there is no doubt that kids are very perceptive and observant.  Can I as an adult regain that wide eyed vision of a child? I sure hope so.  I’m working on it.

Judging the Age of Butterflies

White Peacock ButterflyJudging the Age of Butterflies

The White Peacock Butterfly is found in the southeastern United States through Central American and South America.  This particular specimen was photographed near Naples, Florida. Their lifespan in the wild is one to four months.  Judging by the wear and tear on the wings of this female, this is probably an older butterfly.  Tattered wings are a good indication of where a butterfly is on their lifespan.

Look for my new book, There’s a Bug in My Blossom, available for order now at Amazon and Barnes and Noble!

This website will help you explore and share your experiences!  We can talk about how to see and photograph those tiny things and those that are larger.  We’ll also look at why all of these living things have a place in the grand scheme of things.

 

What things can you see in the garden?  Freddy Squirrel would like to see your pictures and drawings of bugs and other critters you find in your flowers.
