The Moth Post

June 18, 2012

I figured I could wait to visit the bathroom until after I went to the store for the tortillas.  It seemed wrong to ask my husband to go for them, in the interest of getting the dinner in the oven in a reasonable amount of time, since he would never find them but would instead return home to tell me that the Stop & Shop a half mile from our house doesn’t carry them. Aisle seven, by the way.

My light rig-UV light with a Mercury Vapor light attached to a tripod. The UV hangs from the top of the sheet.

After that I thought I better get out there and set up my new mothing rig while there was plenty of light to spare. Since it’s a new one, I could run into a few snags and I wanted to be able to see so I could sort them out. Emptying my bladder would have to wait.

I dashed to the store, finished the dinner and got started on that light set-up and it was all-systems-go by the time sundown came. I was pretty sure I wasn’t in renal failure yet, so I snapped some photos of a couple of moths I saw out by the front porch. Since I work as a mom, wife and naturalist I am, well, a whiz at putting off certain private functions in favor of activities that move the family ship of state forward. Somehow, moths have gotten be a feature on my “must do” list, seemingly ahead even of vital bodily functions. To say that I am a multi-tasker is putting it mildy.

But I am all excited about National Moth Week, a celebration of moths and biodiversity (July 23-29, 2012). It’s the first one ever, and since I discovered what fun “mothing” is, and how much there is to learn, I’ve been avidly trying to soak up as much as I can.  Moths are just beautiful-not at all the plain jane grey and brown things you find in old cereal. They come in every color of the rainbow and there are thousands more species than butterflies. In other countries like England there’s been an interest in moths for many years and there are numerous field guides about their native species. Here, the most recent (until this April) field guide to moths was a Peterson’s first issued in 1922.  The plates were black and white and in general all the moths looked the same.  You had, in my opinion, to be a genius to really identify anything, but some people did.

And now there is a terrific new field guide just published with beautiful plates and commentary.  Also published under the Peterson’s imprimatur, the authors are Seabrooke Leckie (who has a nifty blog The Marvelous in Nature on WordPress) and David Beadle. It’s great. So now anyone can figure out what those moths are that flutter against their back door at night.  And you can participate in National Moth Week. Really, anyone can do it. You don’t actually need any special equipment. Just leave an outside light on from dusk until you can’t stand it anymore and you have to go to bed. You may wish to dive in and get fancy lights-it’s up to you, and it is not only an important area of scientific inquiry, it’s fun!  You can photograph the moths, or just appreciate them. Or, you can go to one of hundreds of moth events that are being held all over the country. You can find out everything about this at the National Moth Week website, along with how-to’s if you want to start mothing on your own.  Take a look at http://nationalmothweek.org/ for more information.  Our moth event at Hill-Stead in Farmington, CT is this Friday, June 22 at 8:30.

American Lady Butterfly
credit: T. Moore

The other day I lay in the grass and searched for butterfly eggs among the Pussy Toes plants.  It was a glorious day, sunny, with gentle breeze and warm earth which felt just right beneath me. I happily spied on the American Lady butterflies as they lit and clambered over the wildflower to find the right places to lay eggs. When I could tell they’d done the deed I’d inch over and, placing my hand lens to my eye I scanned each tiny leaf to see if it sheltered an egg.  I am sure if I hadn’t  seen them ovipositing I could never have found the eggs, since they are not even a millimeter around. Sitting on a leaf they look like translucent, green-tinged tuffets such as might be pulled up to a fairy’s armchair. Minuscule “seams” radiate from a central point at the top and gather on the bottom.  They put me in mind of a pincushion my mother once had, but hers was red.

When you see something like that it makes you realize how much there is around you that you can’t or don’t notice. The American Lady butterfly itself is a lovely creature, and we are fortunate to have them come through this area during their annual migration. The size of the migrations vary widely, so some years just a few flutter through and other years like this one they pour through New England in overwhelming numbers.  I don’t mind a bit being inundated with butterflies.  Who would?  A cousin of the American Lady Butterfly, the Painted Lady,  comes this way too.  Sunny days with a little breeze for lift have made the Hill-Stead meadows seem like a colorful insect freeway.  We have quite a bit of Pussy Toes, a preferred host plant, as well as Pearly Everlasting-related to Pussy Toes and just as relished by the American and Painted Lady butterflies.  So they are out there in colorful multitudes.  They are hard to tell apart-it’s only a matter of a couple of extra dots and they might easily have been classified under one name, with the “extra dot” ones considered a variation.

With names like “American” and “Painted Lady” it sounds as though one bug were upstanding and the other morally derelict.  Since Linnaeus’ time, we’ve had various reasons for the naming of things and before that the Greeks and Romans had their methods.  Darwin’s discoveries threw a wrench into Linnaeus’ system, and Cladistics is a newer game still.  So there is a continuum of naming the more we learn about our world.  Some might say it doesn’t matter, a “rose by another name would smell as sweetly.”  But I’ve noticed that as children grow they like to try on different nicknames like different clothing,experimenting with how a certain identity makes them feel. So names matter.  My husband spent some time as “Jack Blackthorn”, which as a child he thought had a brave and rakish air. But my daughter, who started life with a Chinese name meaning “good luck” and “jade” has not yet made an effort to discard the name we gave her. We chose her first name because we just loved it.  Many parents of Chinese daughters leave the Chinese name in place as a “middle” name, but we didn’t.  Her second name is for my mother, who died shortly before she was born and who would have been besotted with her.  We wanted not to disrespect her origins, but to embrace her entirely as a member of our family as certain as she had come to us “the old-fashioned way”.  We use her Chinese name as a nickname, as it is as surely her name as much as the others.  I love that name too-I used it when we were first together and I snuggled her against me so she would know the love was for her and no one else-days of sharing the caregiver with a dozen others were over. Perhaps at some point she’ll want us to call her something else, or she’ll decide to use her Chinese name.  You never know what kids will do.  I hope I have the sense and good grace just to swallow and use the tag she wants instead of making it all about me.  Giving names is one thing, and accepting them is another.  Unlike plants and bugs, we have some choice in the matter.

Theodate named her house Hill-Stead.  As a name it perfectly conveys the two most important elements in the Hill-Stead backstory, specifically that she was deeply concerned with and connected to the land the house sits on.  The home was sited at the top of a hill with the help of the landscape architect, exploiting the natural features so that each window framed a perfect landscape. They could have sited it in many places on over 250 acres of land, but they faced it toward the Barn Door Hills.  Of equal importance is “Stead” meaning steady, rooted home.  Theodate was determined to create a secure and anchored place for her family to live, underscoring her need for hearth and home to be rooted in the land and nature.

If You Plant It, They Will Come

March 27, 2011

Some of my friends are on a “cleanse”. You need the book  to participate- $9.16 on Amazon.com.  You give up “obstacles to digestion” which apparently include eggs, nuts, dairy, tomatoes, eggplant, potatoes, peppers, meat, soy, cheese, wheat, and coffee.  Since this doesn’t leave a lot you can actually eat, there is a line of shakes and supplements, $425 for the most popular package.  Evidently people are contaminated with poisons from  a diet which presumably includes tomatoes and peppers (see above list for other possibilities), and it is recommended that the cleanse continue for at least a month.  If you have had the habit of eating any “allergen, mucous-forming or inflammatory” foods (see above), then you need to take and stay on a pre-cleanse program for a time before you can get into the actual cleansing. The more poisonous your previous diet, the longer the pre-cleanse.  Then comes the gastrointestinal scrubbing during which you will need to take pills with names like Clear, Equilibrium, Pass, Ease and so on. The image I got when I heard about these wasn’t good at all, especially “pass” and “ease”.

When you complete the tour of duty, you will feel energy and clarity, and be at least $434.16 lighter.  Starvation for the privileged.  But if you want to be on the cutting edge of weight loss fashion, look no further.  The book alone is a runaway bestseller.

I am polite about all this.  But I shudder at the frivolity while people the world over could eat for months on $425 and feel overfed.  Being riven with hunger is torture. Real starvation means the Cheezits aren’t six feet away in the cabinet if you tire of it.  The price of such hunger far exceeds $425. It is known, tragically, by millions.

On another plane, but no less pitiable is the deprivation known this winter by animals and birds throughout our area.  As the snow melted here at Hill-Stead I sadly found quite a number of bird and animal corpses.  In a harsh winter, hunger is a ruthless creditor.

This year birds gobbled up late summer berries like wild grape, pokeweed, poison ivy and blueberries before the fall was even over, so they had to start in on winter berries early.  Winter berries include cedar, sumac and winterberry.  They were in turn eaten up early. Starvation set in and with no other crop to draw from, many birds switched to eating alien and ornamental plants like multiflora rose and bittersweet. Without these foods as sustenance, I would  have found quite a few more corpses during my springtime wanderings. This got me thinking.  Because the birds had to switch over to eating invasive plants , it may mean that invasives will spread more than usual when spring warms up and the seeds dispersed by the birds begin to grow.

I began to consider the further effect of an increase in alien plants. I’ll use Hill-Stead’s experience with a butterfly, the Baltimore Checkerspot, as the perfect example. This insect has a favorite food.  And like a picky child, if the favorite food is unavailable it simply won’t eat.  But the bug has more gumption than most children, and it dies out in places where its’ preferred plant has died out.  No plant, no bug.  In this way, once common insects become more local then gradually go extinct.  Hill-Stead used to be a last gasp location for the Baltimore Checkerspot since we had quite a bit of turtlehead, the favorite plant. But the meadow began to be mowed in wider and wider margins, and the turtlehead went.  It was long before my time and anyone else here now. But the butterfly census folks still shake their heads, and so do I.  The Baltimore Checkerspot is not unique in its stubbornness. Every single insect is the same.

But here’s the thing: 96% of terrestrial birds (as opposed to sea-going birds, for example) feed their babies on insects and spiders. What determines how many and what kind of insects are around?  Plants! So, if we keep creating scenarios where invasives multiply, we will continue on a crash course with insect extinction and by extension bird extinction and by further extension, well, you get the idea.

Now it probably isn’t anyone’s specific fault that we had a bad winter and the birds had

Serviceberry (native)

to resort to eating multiflora rose hips.  But it is our fault if we fail to increase our use of native species when we plant around our homes, parks and ornamental gardens.  In this way, the birds and insects and everything that depends on them will have a leg up by having the proper food to eat. More native plants, more insects, more birds. More, please.

To New Beginnings

March 11, 2010

The pussy willows were in full bloom today, and life is waking up again throughout the estate. Today I even saw a butterfly -a tortoiseshell type, the earliest I’ve ever seen one.  A butterfly afficionado I know says it might be a record.  Along with Mourning Cloaks, tortoiseshell butterflies are seen in the earliest days of spring. I also spied jumping spiders in the meadow, and incredibly, a grasshopper. The Northern Water Snake that naps near the bridge down by the pump house is awake, and a turtle plopped into the water as I walked along the sunny side of the pond.  Bluebirds circle the newly-cleaned bird boxes. Skunk cabbage is well along now and woodcock are skulking in the woods surrounding the fields.  They rest and forage in the wet woods during the day and come out at dusk to do their bizarre dancing and calling.  Wood frogs are awake, too.

We’ll have cold, raw days yet before spring takes a real foothold, but the first sunny days of the season provide such relief even after an uneventful winter.  Today you could almost hear flowers pushing up earth and green shoots unfurling. Beginnings are so much fun.  First date, first dance, first day of school, first car, first love, first kiss, first flower, first caterpillar, first red-wing blackbirds, first phoebes. You might say that without endings, there wouldn’t be beginnings and in a limited sense this may be true.  Organically speaking, there is a cycle of birth and death that doesn’t vary.  But there are human beginnings that seemingly spring from nowhere, and, heaven knows, unforeseen conclusions. Beginnings are rarely bitter, even in plants this is true.  Dandelion salad, for example, is lovely when the leaves are small.

Circumstances and sentiment can all too often dictate endings, when bonds become in their own way overgrown and too big for the container. Last misunderstanding, last farewell, last regret.  At least nature’s endings are free of recrimination. The past melts away graciously and makes way for the new.  Last snowfall, first snowdrop.

Trolls’ Spindles, Eye Pokers and Adder’s Servants

Red Admiral Butterfly

Red Admiral Butterfly

Birding people become butterfly enthusiasts after “peak” birdwatching ends in June. Butterflying is really a much better hobby since it doesn’t require getting up so early in the morning!  Butterflies operate a lot more like people than birds do: they prefer to get going when the sun is up and things are already nice and warm. As small as they are, in this they show a lot more sense than birds do.

Some nature enthusiasts don’t know when they’ve got it good. After running around all spring after migrating birds who get up at ungodly hours, you’d think they’d be happy to latch on to butterflies and leave it there. Nope. Not content to look at butterflies in a leisurely way, go home and have a nice glass of iced tea in the shade, many have to up the ante. They get sucked into studying dragonflies.

Do you remember when dragonflies were known as “devil’s darning needles”? Apparently this related to the old wives’ tale (and as an actual old wife I feel I can use the phrase without prejudice) that dragonflies would sew together the lips of wicked little children as they slept. Though this is not an altogether bad idea, it is untrue. Still, it’s a good example of the notion that dragonflies and their skinnier counterparts the damselflies (note that the thin one gets the cuter name,) have in many cultures been associated with scary, sometimes supernatural happenings. Legend in Sweden has dragonflies used by the Devil as devices to measure the weight of souls. I hope they need extra dragonflies when my time comes.

Right around the time butterflies get going, onodates (dragonflies and their relatives) start zipping around ponds and wet areas. In a beauty contest, there aren’t too many that would vote for a dragonfly over a butterfly, except maybe another dragonfly. And really, they should know. A dragonfly’s eyes occupy three-fourths of its head. Their eyesight is really, really good. Thousands of distinct lenses occupy each individual eye. Known as “compound eyes”, these include specific lenses in aid of seeing directly above, straight-ahead and a bifocal-like pair for magnification.

I suppose it can be said that hobbyists who follow both butterflies and dragonflies enjoy going from the sublime to the ridiculous. And if you feel that butterflies occupy the “sublime” end of the spectrum, there is little doubt where the dragonfly with its bulbous eyes, flashing wings and militaristic patrol of his little patch of pond belongs.

But don’t lose respect for the dragonfly. His wings are of prehistoric design, yet he is more nimble than many insects with wings of more new-fangled engineering. Lab experiments show that with their primative makeup, the dragonfly wing should beat about 30 times a second. A honeybee can do 250 beats, and there are some no-seeum types that can achieve more than 1,000. Nontheless, a dragonfly can catch either of them in a race. Why? NASA engineers as well as the US Air Force and Navy put dragonflies in wind tunnels and used strength meters to figure out the secret. Apparently by moving its two sets of wings in opposition to one another they create more than three times the “lift” for their weight than bugs with “better” designed wings.

It’s an unblalanced equation weighing  the value of one creature against another. I don’t know whether the dragonfly is more favored by nature than the butterfly or the other way round. I am always astonished at the things I learn about  animals and plants.

It adds up to giving up my iced tea  and butterfly walk.  There are a whole bunch of really cool dragonflies down by the pond and a good hundred or two of swell books about them I don’t own yet.
