Bald-faced Hornet Queens Laying Specialized Eggs

A Bald-faced Hornet colony begins in the spring when a queen emerges from winter hibernation. The queen builds a small nest, creates a few brood cells within the nest, deposits eggs in them and feeds the larvae when they hatch.  These larvae are female workers — they will continue the nest building, food collection, feeding the larvae and protecting the nest while the queen concentrates on laying eggs.

During the summer the colony (and size of the nest) grows until there are between 100 to 400 workers. Toward the end of the summer the queen lays two special types of eggs. The first will be, like the workers’ eggs, fertilized eggs that will develop into females, but these females will be fertile (and develop into queens). The second group of eggs will be unfertilized eggs. These eggs will develop into fertile males. The maturation and emergence of the new queens and the fertile males marks the end of the functioning of the colony. At this point the workers are not replaced and die out. The ruling queen, having served her purpose, also dies. The newly-emerged adults (queens and fertilized males) leave the nest, mate, and the fertilized queens overwinter and begin their colony cycle all over again in the following spring.  Some small nests complete their cycle by mid-September, while some large nests are still going strong until the cold kills the larvae in late November.

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!


Signs of Striped Skunks

If you are finding small, conical pits in your lawn, you probably have a striped skunk to thank for reducing your grub population.  During the spring and summer, invertebrates make up a large percentage of this nocturnal omnivore’s diet.  With the help of their well-developed sense of smell and their long nails (which make them excellent diggers), they locate, gain access to and consume subterranean insect larvae with relative ease.   Another sign of skunk activity, in addition to lawn divots, are the excavated ground nests of yellowjackets.  If they’ve met with success, skunks will often leave sections of empty, paper cells scattered about the nest site.  Apparently, even though yellowjackets can sting multiple times, they’re not very effective at discouraging foraging skunks.  Should you be so inclined, a close examination of skunk scat will reveal bits of insect exoskeletons, as well as the bones and hair of small rodents.  The pictured scat (next to the divot) contained, in addition to insect parts, the fur of another nocturnal animal, a flying squirrel.  (Thanks to Emily and Joe Silver for photo op.)
