For the Birds: Dragonfly fun facts

I’m a big “fun facts” guy. Thankfully, the internet is filled with these interesting tidbits of information. 

You could find amusing information on just about anything you can think of: politics, art, sports, human biology, libraries, history. You name it, it’s out there on the web.

The animal world, of course, is no exception. Fun facts abound on the internet about earthworms, cicadas, robins, moose, musk ox, and countless other fascinating members of the animal kingdom.

I wrote recently about a few hot-weather walks I took through New England meadows. I focused that column primarily on butterflies, but I want to turn the attention to another common sighting I had on those walks: dragonflies.

These large insects have fascinated people for as long as people have been fascinated by things. Dragonflies can arouse amazement, fear or curiosity in humans. For me, it’s a combination of amazement and curiosity. I used to fear them when I was a kid due to a lack of understanding about them. They may be intimidating-looking, but they are as harmless as they come in the insect world — at least the ones we have in New England. (See, I snuck in a fun fact without even setting it up.)

OK, now for the set up: Dragonflies arouse curiosity in people for many reasons, such as their menacing appearance, aerial acrobatics, and ability to eat copious amounts of mosquitoes. Here are some other facts about dragonflies that you may or may not have known previously.

Dragonflies have two eyes, but each compound eye is made up of up to 30,000 ommatidium, or facets. The eyes make up most of a dragonfly’s head.

Dragonflies can fly in any direction and can hover for long periods of time. They can also fly upwards of 30 miles per hour.

That flying ability makes dragonflies excellent hunters, eating large amounts of small flying insects, but they can also be the hunted. I’ve seen birds such as green herons and purple martins snatch dragonflies out of the air.

Dragonflies are insects and therefore have six legs, a head, thorax and abdomen. They also have four wings, and the fore wings and hind wings are controlled separately, hence their awesome aerial abilities.

Dragonflies can be monomorphic (male and female look alike), dimorphic (male and female look different) or polymorphic (much variety even among males and females.) The most common colors for dragonflies in New England are blue and green, but there are also red, amber and white dragonflies here.

There are only a handful of dragonfly families that occur in New England (such as skimmers and darners), but there are about 200 species among those families in our region. The largest dragonfly in New England is the green darner, which is more than three inches long.

Dragonflies live all over the world, although most live in warm climates.

Eggs are laid in or near water and larva live for about a year in the water. After emerging, dragonflies live for only a few months as adults, if they are not eaten by something else sooner than that.

A group of dragonflies is called a swarm. They are multi-generational migrants, meaning the ones that fly south are not the same ones that return north.

Dragonflies make for interesting photo subjects. They often return to the same perch over and over, making it easier on photographers.

Bald eagles steal the show

Savanna and I decided to venture outside the friendly confines of New England and take a short drive to the Bashakill Wildlife Management Area. It’s a beautiful area teeming with wildlife, great scenery and surprises around every bend as you paddle along the narrow serpentine river. It is a New York state Bird Conservation Area and located between the Shawangunk (“Gunks”) and Catskills mountains.

I discovered this gem of a place when I worked for a short time in Middletown, N.Y. about 20 years ago. I’ve returned now and then ever since, but it had been quite some time since my last visit. So one day last weekend we strapped the canoe on the car the night before, rose before dawn and headed west.

Other than my usual access road being closed due to construction, everything was as I remembered it. The water channel was a bit more narrow than usual, but that’s because it was August and it hadn’t rained in quite some time.

Wood ducks, as usual, were the dominant species. There must be thousands there and we must have seen a few hundred of them. Red-winged blackbirds and a lone kingfisher were other usual sightings. At one point we saw a bush in the distance in the swamp that was literally bursting with swallows. The swallow migration has begun and this bush looked like a Christmas tree covered with live ornaments.

But the most memorable sightings were of the resident adult bald eagles. We saw the male first and then the female. As with most birds of prey, female bald eagles are larger than males. A man we met in the parking lot later — who identified himself as the “local eagle guy ” — who said there were two young eagles that year, too, but they like to stay hidden in the woods away from the open swamp. It was good to hear that the adults continue to have breeding success there.

Bald eagles are making a strong comeback throughout the U.S. and New England and nearby N.Y. are no exception. Just like the tremendous comeback of the osprey over the last few decades, it’s nice to witness another iconic species on the rebound. Now, let’s just keep it that way.

Birding by canoe: Red-winged blackbird

One of my favorite ways to view wildlife is in my canoe. I can’t even begin to guess how many miles my 14-foot Radisson has in it. There will be more exciting photos coming up from a recent canoe trip, but for now here’s a cool shot of a red-winged blackbird.

Butterfly extra: banded hairstreak, and bonus monarch

Revisiting last week’s “Butterfly Weekend” quickly …

Armed with only my phone camera on a meadow walk with Savanna this morning, we came across this banded hairstreak, a tiny and handsome butterfly of New England.

Two weeks ago I walked this same meadow on a 90-degree, humid day and butterflies were literally everywhere. This morning was cool with a hint of fall in the air and goldenrod taking over as the dominant flower species. There were plenty of butterflies to be seen but not nearly in the same numbers. A beautiful and satisfying meadow walk just the same.

Stranger things: Dragonflies

Many people wouldn’t consider dragonflies strange because they are so common and part of our daily summer lives. I am including them in the Birds of New England ‘stranger things’ series because of their awesomely menacing appearance and otherworldly flying ability.

Dragonflies have only two eyes, but they make up most of the insect’s head and have up to 30,000 ommatidium, or facets (see close-up photos). I’ll post more information about dragonflies in next week’s For the Birds column.

The four wings of a butterfly

Look back at my “Butterfly Weekend” posts from last week and check out the vast majority of butterfly photos published elsewhere and tell me how many wings a butterfly has. From most photos, it appears as if butterflies have two wings, just like birds.

But butterflies, of course, have four wings, even though it is rarely apparent by watching them fly or sip nectar from a flower. Each wing we see is really two wings: a hindwing and forewing.

I was lucky enough to catch this shot of an eastern tiger swallowtail, which clearly shows the four wings of a butterfly. Nature never fails to astound.

Here’s the same butterfly as it’s usually seen and photographed:

For the Birds: Another hot summer’s day walk

Birds were scarce on the walks, as they usually are on hot summer afternoons. In what has become somewhat of an annual event for me, I picked a blisteringly hot and soakingly humid summer afternoon and went to a New England meadow to see what critters were flying, jumping and crawling about.

Butterflies were the main attraction, as they usually are, followed closely by dragonflies. Monarchs were the dominant butterfly species, but eastern tiger swallowtails were in abundance as well. There were also high numbers of black swallowtails, skippers, buckeyes, sulfurs and other delicate winged beauties.

It was nice to see so many monarchs, of course, as this iconic species is in serious decline and in recent memory was thought to perhaps be going extinct. From what I have read, the 2019 population is well above the previous year, which is terrific news. It is not time to let down our guard, however. Populations of animal species can vary widely from year to year and we want to make sure we keep doing all we can to help monarchs survive.

The meadow in which I walked is teeming with milkweed. That, of course, is the main food source for monarch caterpillars, but also a favorite nectar stop for adult monarchs and other butterfly species. I would say at least 80 percent of the butterflies I saw feeding during my walks were sipping from milkweed flowers.

Yes, the butterfly season is definitely in full swing. It will remain that way for the next several weeks before tapering off as we head into fall. I will return frequently to this and other meadows to see the butterflies and other critters getting ready for the colder months.

As I mentioned, the bird activity on these walks was rather slow, but not nonexistent. I did notice a rather large flock of bobolinks, a mixed flock of males, females and youngsters, flying around, which was nice to see.

I also saw a few immature bluebirds with their dull plumage and spotted chests. Goldfinches were a frequent sighting, and without a doubt, the most numerous bird I saw. Besides that, a song sparrow or two and the odd hawk flyover were about it for bird activity.

These sweltering strolls into the meadows each summer have become one of my favorite annual traditions. I’m certainly not saying butterfly photography is easy, but they are certainly more cooperative than most birds. Plus, the colors you get on the photos from the butterflies and flowers are always inspiring.

Many more photos of the walk are available on the website www.birdsofnewengland.com. Feel free to check it out and also remember to send me your most recent sightings, be it birds, butterflies, or whatever else you have seen in the natural world.

Butterfly Weekend: Bonus eastern tiger swallowtail photos

I’ll wrap up Birds of New England’s first unofficial Butterfly Weekend with some bonus shots of eastern tiger swallowtails. Monarchs may have been more numerous on my recent walks, but swallowtails proved to be more cooperative.

I hope you enjoyed Butterfly Weekend. Thanks for supporting Birds of New England.

I see far more eastern tiger swallowtails than black swallowtails so it’s always a treat to see these handsome fliers around.
