A Great Christmas Present!

If you’re looking for a present for someone that will be used year round, year after year, Naturally Curious may just fit the bill.  A relative, a friend, your child’s school teacher – it’s the gift that keeps on giving to both young and old!

One reader wrote, “This is a unique book as far as I know. I have several naturalists’ books covering Vermont and the Northeast, and have seen nothing of this breadth, covered to this depth. So much interesting information about birds, amphibians, mammals, insects, plants. This would be useful to those in the mid-Atlantic, New York, and even wider geographic regions. The author gives a month-by-month look at what’s going on in the natural world, and so much of the information would simply be moved forward or back a month in other regions, but would still be relevant because of the wide overlap of species. Very readable. Couldn’t put it down. I consider myself pretty knowledgeable about the natural world, but there was much that was new to me in this book. I would have loved to have this to use as a text when I was teaching. Suitable for a wide range of ages.”

In a recent email to me a parent wrote, “Naturally Curious is our five year old’s unqualified f-a-v-o-r-I-t-e  book. He spends hours regularly returning to it to study it’s vivid pictures and have us read to him about all the different creatures. It is a ‘must have’ for any family with children living in New England…or for anyone that simply shares a love of the outdoors.”

I am a firm believer in fostering a love of nature in young children – the younger the better — but I admit that when I wrote Naturally Curious, I was writing it with adults in mind. It delights me no end to know that children don’t even need a grown-up middleman to enjoy it!


Autumn Meadowhawks Mating

Meadowhawks are the only small red dragonflies seen in New England (most males are red, most females are brown).The latest species of dragonfly flying in the fall in this area is the Autumn Meadowhawk (Sympetrum vicinum), which doesn’t emerge until mid-summer. It seems a bit incongruous to observe these dragonflies not only flying, but mating and laying eggs in late October, but that is exactly when you can expect to see them. Until there have been several hard frosts, these winged masters of the air are able to keep active by basking in the sun and warming their flight muscles. The two pictured Autumn Meadowhawks are copulating in the typical “mating wheel” fashion, with the male grasping the female behind her head while the female places the tip of her abdomen at the spot on his abdomen (the seminal vesicle) where he stores his sperm. The female Autumn Meadowhawk lays her eggs in tandem with the male (his presence prevents other male meadowhawks from replacing his sperm with their own).


Twelve-spotted Skimmers

Twelve-spotted Skimmers are classified as “King Skimmers,” all members of which are large and conspicuous, often with distinctive wing patterns.   Male Twelve-spotted Skimmers (pictured) have a grayish bloom on their abdomens and each wing has three dark spots with white spots in between them.  Females have brown abdomens and no white spots on their wings.  All summer you can see males flying back and forth short distances along the shores of ponds and over water, hovering as well as perching.  They are territorial and patrol over water, loop-de-looping with competing males.  A small number of Twelve-spotted Skimmers occasionally take part in Atlantic Coast migrations.


Beaverpond Baskettail

Beaverpond Baskettail dragonflies have an early flight season, first appearing in May in the Northeast.  The males (pictured) cruise over the water (often beaver ponds, hence their name) as well as the shore in sexual patrol flight, flying back and forth over the same area repeatedly.  After mating, the female accumulates a large egg cluster at the tip of her abdomen, and as she drags it along the surface of the water, a long string of eggs is draped over plants.  Once these strings expand, they can be several feet in length and an inch or more in diameter.


Naturally Curious wins National Outdoor Book Award

I am delighted to be able to tell you that this morning I learned that NATURALLY CURIOUS won the Nature Guidebook category of the 2011 National Outdoor Book Awards.  I’m honored and humbled by this recognition.   http://www.noba-web.org/books11.htm


Damselflies Laying Eggs

Different species of damselflies and dragonflies emerge throughout the warmer months of the year.  Entomologists lump them all into three categories  –  “spring,” “summer” and “fall” fliers.  Fall fliers generally emerge in mid-summer and fly through early to mid-October.  Recently, at a nearby pond, it appeared that damselflies were taking advantage of the lingering warm days by mating and laying eggs before cold weather set in.  Nearly every cattail leaf was loaded with several pairs of damselflies, most of which were still attached to one another (the males continue to grasp the females after mating with them to prevent the removal of their sperm by other males).  When I returned the next day, there wasn’t a damselfly in sight.


Black-tipped Darner

I thought some people might like to see what the newly-emerged Black-tipped Darner dragonfly whose picture was posted three days ago  eventually looked like.


Dragonfly Eclosion – Emergence of Adult

8-4-11 Dragonfly  Eclosion – Emergence of Adult

This slideshow requires JavaScript.

At the end of its larval stage, a dragonfly larva crawls out of the water where it’s been living and climbs up onto emergent vegetation, or a nearby rock, where it clings as its skin splits along its back and head.  The adult winged dragonfly pulls itself out of its larval skin through this hole, and grasps the skin (or vegetation or rock) while it pumps its body full of air and sends fluid into its wing veins.  This fluid causes the wings to enlarge — the wing expansion that is evident in these two photographs took place in less than ten minutes.  When it first emerges from its skin, a dragonfly is pale and soft, and the wings have a characteristic pearlescent sheen, as in these photographs.  Within a day or so the wings lose this sheen, the body hardens and colors start to develop.


Dragonflies Mating

7-19-11  Mating Dragonflies

Dragonflies (and damselflies) form what is called a “mating wheel” when they mate.  The male (top) grasps the female at the back of her head with the appendages at the tip of his abdomen. The female then curls her abdomen forward so that its tip reaches his sex organs and receives his sperm.  After mating, the male may continue to grasp the female and accompany her while she lays her eggs, to prevent another male from removing his sperm from the female and then mating with her.
