Dragonflies capture summer

Summer won’t be over for a while in my book—not as long as there are dragonflies around. I think I’ve seen more dragonflies this year at the Chicago Botanic Garden than I have in the past ten years combined. The quick, strong fliers seem to be everywhere.

Some of the dragonflies migrate south toward the Gulf Coast through September and maybe beyond. With the help of citizen observers, scientists are studying the migration patterns of this fascinating insect, which has a near 360-degree field of vision that helps it avoid predators.

The most abundant dragonfly I’ve seen this year is the Eastern pondhawk, with blue dasher dragonflies coming in a close second. I’m also seeing quite a few damselflies, which are generally smaller and more thin-bodied than dragonflies and tend to hold their wings above their bodies. (See my blogpost Damselflies 101 for more information.)

Dragonflies and damselflies, both in the order Odonata, can spend several years as aquatic nymphs before they emerge into the beautiful winged insects we see on land, which is why you will often see them around water. They are fierce hunters in both stages. They don’t bite or sting humans, though.

Dragonflies can be found here from March through the first hard freeze in the fall. Right now, you might even be lucky to find yourself in the middle of a migrating swarm of green darners, black saddlebags, or wandering gliders as they head south. About 90 different odonates can be found in the Chicago area. Each one is a delight to behold.

Dragonflies are territorial and will often chase off other dragonflies, only to return to their favorite perch. A favorite place to find them at the Garden is around the waterlilies and lotus blossoms, but you can spot them throughout the 385-acre grounds. Drop by and keep an eye out for the dragonflies near the late-summer blooms.

Warbler Heaven

A lot of birds migrate through the area this time of year, but I have to say warblers are my favorites. The other day, when the rain cleared and the sun came out, I found myself in warbler heaven!

As soon as I walked out of the Visitor Center, I saw movement in the trees next to the bridge: my first warbler of the day—a prothonotary! (Protonotaria citrea)—an uncommon warbler, and the first time I’ve ever seen one at the Chicago Botanic Garden! Next stop: the top of the Waterfall Garden. The birds were hopping! Here I added eight more warbler species, including yellow-rumped, palm, black-and-white, Cape May, American redstart, Wilson’s, magnolia, and yellow warblers! Wow! So much fun! I also saw red-eyed and warbling vireos, a scarlet tanager, and a ruby-crowned kinglet, to name a few.

After delighting in the abundance of birds for a few hours, I slowly made my way back to my car, choosing to walk under the amazing flowering crabapple trees. Just at the end of the line of trees I heard what I thought was another warbler. I couldn’t quite see what it was. I tried calling it out, and to my delight, out popped the most beautiful male northern parula warbler (Setophaga americana). He hopped right onto a flower-filled branch and seemed to pose while I got some photos. I’ve only seen a parula a couple of times before, and never this close, and never on such a pretty perch. A perfect way to end my journey in warbler heaven.

While I can’t promise you will see this many warblers in a day, there is always something to see, and the fun part for me is never knowing just what might show up. Last week it was a white-eyed vireo (Vireo griseus). This week, warblers. Next week, who knows? All I do know is I’ll be out there to see what wonders there are to discover and then I’ll be in heaven again.

Photographing Orchids

Compared to photographing flowers outside, photographing in the Greenhouses will be much more challenging and darker than you think.

Photograph the Orchid Show through March 13, 2016.
 
Tripods and monopods are allowed in the Orchid Show on Wednesdays during public exhibition hours. Enter your photos in our digital photo contest here.

It may be bright outside, but the light in the greenhouses is being filtered through glass and other plant material; be aware that it will be even darker on overcast days. Most people will be hand-holding cameras, so getting shots that are sharp will take some adjustments. Here are a few things you can try:

Use a shorter lens.

This will be a bit of a compromise, as many of the orchids are up high or hard to reach. It would be nice to use a longer lens to get photographic access to more of the flowers in the Greenhouses. However, a shorter lens—100mm or less—is easier to hand-hold, and has a better chance of capturing sharp images at a slower shutter speed. (Typically, you want to have at least 1/400th of a second for a 400mm lens, or 1/100th of a second for a 100mm lens, etc., so the shorter lens will gain you two stops in this example—a significant benefit when taking hand-held shots.)

Watch for what is in the background.

It is easy to be distracted by the beauty of the orchids and then get home and realize there are many unwanted elements in your photos. One easy option is to move in closer. When you get closer to the flower, you will get less background around the flower. Find flowers that are near the edge of an aisle—you will then be able to move your camera slightly up or down, or left to right, to get a pleasing background. Sometimes just an inch of movement can make all the difference.

Increase your ISO.

Many of the newer cameras have improved sensors that let you increase the ISO and still get clean images with little noise. I like to do an ISO test before going out to shoot to see just how far I can push the ISO and still get images I find pleasing. It’s best to do this before you are on site so you will be able to review the images on a large screen and know what will be acceptable to you on the day of your visit. Every camera is different, and what may work for me may be too grainy for you. Most cameras will provide nice images in the 400 to 800 ISO range, and some can go much higher.

Use your flash.

I much prefer natural lighting, but in the Greenhouses on a cloudy day, there may be no other option for getting that shot of “the most beautiful orchid you have ever seen” that is hiding in the shadows.

When using my flash, I can add some extra depth of field. Here I was able to get most of the flower sharp. Photo ©Carol Freeman

Increase your depth of field.

Orchids are tricky to photograph, even in ideal conditions. Many of them are deep flowers and require a large depth of field to get a pleasing amount of the flower in focus. Increasing the depth of field, however, comes with a price, as the increased depth will often allow much of the background to be in focus as well. And in the greenhouses, you may not want what is in the background to be in focus, especially windows, people, or other parts of the building. Hand-in-hand with depth of field is plane of focus. Many orchids have very interesting centers, almost like faces. Be sure to get those features in focus to make the whole photo look sharper.

Have fun, experiment with different apertures, and get creative with composition! There is no right or wrong way to photograph these amazing flowers. They are here for your enjoyment and all that is needed is your appreciation.

Fall on the Prairie

While summer blooms elsewhere are winding down, the Dixon Prairie is still alive with many fall flowers.

Asters, sawtooth sunflowers, gaura, and goldenrod are going strong. All of them are abuzz with bees and other insects. Grasshoppers dance from plant to plant. Butterflies fuel up for a last fling or long journey.

Grasses, some with tiny fragrant flowers, sway gracefully; many have grown more than 7 feet tall in this one growing season. Early morning dew transforms the seedheads into works of art. Silken strands of unseen spiders glow in the sunlight. Flocks of goldfinches munch on seeds, stocking up for winter, chirping their happy tunes, while shy sparrows occasionally pop up from the shadows, giving us a glimpse of their subtle beauty. Milkweed seeds blow gracefully in the wind.

The prairie truly must be walked to be appreciated. There is so much diversity, and so many stories to tell.

Touch a compass plant leaf on even the hottest day and it will be cool to the touch—with roots going down 14 feet, they pull up water that is chilled underground.

Monarchs live in symbiosis with milkweed plants (as do many other insects). Look closely and you may see a whole world on a milkweed plant.

Surprises can be anywhere—a hummingbird zipping by for a quick sip, a great blue heron flying overhead, drama as a hawk dives down to grab a vole. Fall on the prairie is colorful, alive, and a place of great wonder not to be missed.

Damselflies 101

The Chicago Botanic Garden is a great place to find damselflies. You can find them in every location here, and different locations will often yield different species.

For example, you might find stream bluets along the river and orange bluets hanging out on the lily pads. Most species measure about an inch in length and can be easily overlooked, but when you take time to slow down and search for these tiny gems, you will be rewarded with finding some of nature’s most beautiful hunters. Indeed, these tiny insects are fierce hunters—but don’t worry, as they neither bite nor sting humans. Their preferred food choice is other, smaller insects (including mosquitoes).

The main differences between dragonflies and damselflies are their size and wing positions. Damselflies, in general, are smaller, and hold their wings over their abdomens. Dragonflies tend to be larger, with a heavier body, and hold their wings out to the side.

The most common species around here is the eastern forktail damselfly. Identifying them can be tricky, as they come in several different varieties! The males and females look very different from each other, and the females change color as they age.

I like to get out early in the morning. The light is low, there is often dew, and the insects move a bit more slowly until they warm up. One of my favorite places in the Garden to photograph damselflies is in the Dixon Prairie. They like to hang out on the grasses there. Walking slowly on the path next to the plants, you will see what look like tiny flying sticks. Damselflies will often congregate in one area and, if disturbed, sometimes land just a short distance away. I like to use my 105mm or 200mm macro lenses to photograph these beauties. They will fly until the first really hard frost. There are dozens of species native to this area—all of them beautiful and fierce hunters.
