Insects

Summertime ushers in a bevy of fresh fruit enjoy and in no time, a bevy of fruit flies. With a keen sense of smell, fruit flies hone in on a juicy cantaloupe or overripe bananas tossed on the compost pile. Although they're a pest in the kitchen, fruit flies have been a focus of research for over 100 years, and today there are hundreds of labs dedicated exclusively to studying them.

We’re standing up to our shins in Turkey Pond, on a warm July morning with Pam Hunt, a biologist with New Hampshire Audubon who has spent the last five years organizing, in conjunction with NH Fish and Game, the New Hampshire Dragonfly Survey. Hunt trained about a hundred volunteers to gather data and help map the distribution of dragonflies across the state.

For students hoping to get into a competitive college or university, high SAT scores are crucial. On today’s show, law professor and civil rights activist argues that the SAT is a more accurate measurement of family wealth, race and ethnicity than merit. 

Then, The Uncommon Core, our series on offbeat college courses, continues with golf course management. We’ll also hear from a husband and wife research team going to great lengths to end the bedbug epidemic– including offering themselves up as food!

While hiking on Mount Monadnock this summer, I witnessed an odd phenomenon: nearly-motionless hovering insects with orange-yellow stripes over a dark body suggesting wasps or bees. The tight aerial formation of insects hovered at eye level in a shaft of sunlight over the trail.

The “Hover Flies” - sometimes called “Flower Flies” - belong to a LARGE group in the Order “Diptera” (the true flies). Those in the Family “Syrphidae” have only one pair of wings. All wasps and bees have two pairs of wings.

Something Wild: Dragonflies Winging South

Late summer brings cool nights and clear air - and winged migration. Along with birds heading south, there's a few butterfly, moth and dragonfly species that respond to the migratory urge.

One dragonfly - the common green darner - has been studied with results that suggest there's a lot of similarities between insect and bird migration. Tiny radio transmitters were attached with eyelash adhesive to green darners which were tracked by plane and ground crews.

As Fresh Fruit Ripens, Fruit Flies Multiply

What Are Japanese Beetles Good For?

Mid-summer brings Japanese beetles to the garden, clustering on their favorite foods: the leaves of raspberry, grape, and garden roses. In the vegetable garden, the lead shoots of pole beans are another tasty target. I know gardeners who find a daily ritual of flicking beetles into a container with water and a drop of liquid soap to be very therapeutic. Beetle demise is quick. These are people who typically release indoor spiders and wasps to the outdoors, but damage to the garden is another matter.

Behind recent declines in bee populations are threats as diverse as pesticides, disease, and climate change.  And fewer bees could mean a widespread hit to many types of agriculture. We’ll talk with beekeepers and researchers about what they’re seeing,  also what the future might hold, and what could be done.

N.H.'s War On Invasive Bugs & Plants

Jun 18, 2014

In New Hampshire lakes, rivers and ponds, non-indigenous plants have moved in choking out the natural flora and fauna, but volunteers and state officials have taken up the fight against them. We’ll look at the latest in that fight, as well as invasive insects from the Emerald Ash Borer to the Wooly Adelgid.

Where Have All The Monarchs Gone?

A lot of people are asking this question, concerned at the diminished numbers of this most charismatic butterfly.  Not many schoolchildren this fall will be able to watch caterpillar transform into chrysalis and then glorious adult—metamorphosis in action.

Monarchs are celebrated for their fall migration to Mexico, but the population that spends the wintering there is experiencing a decline. In fact, this past winter it was the lowest on record.

Nature's Obligate Relationships

It is the height of monarch butterfly season in New Hampshire. Though fewer migrants have returned this year. They're producing the generation that will undertake one of the most impressive migrations: two-thousand miles to overwinter in Mexico.

Adult butterflies feed on the nectar of many different flowers but require very specific plants when laying their eggs. Eggs hatch into caterpillars that feed only on the leaves of particular species.

Yellow Jacket Season

Forests are often bone dry at the end of the hot summer. When dusty leaves of poison ivy and wild grape vines display the first crimson tinge of fall, underground “yellow-jacket” hornet nests reach their maximum annual size and ferocity beneath brushy fields and woodlands.

The papery hornet nests are packed with nutritious, fat and protein-rich larvae. The grubs are defended aggressively by agitated worker hornets that will soon lie dead after the first hard freeze.

One more reason to be thankful, New Hampshire: we did NOT experience the periodic cicada invasion this summer. You've likely heard about the mass synchronized emergence of billions of periodic cicadas this summer across the Eastern Seaboard from Virginia north to New Jersey, New York and as far as northern Connecticut - NOT New Hampshire.

Fireflies-- Beyond the Magic

The twinkling fireflies of a summer night bring a little magic. If we think beyond the twinkling, we probably realize it is courtship in progress: the signals of males and females.

There are a couple dozen firefly species in New England, each with a unique series of flashes, from males in flight to females perched below. Beyond the magic, very few people have knowledge of the medical benefits as well: the use of a firefly's light-producing chemicals in bioluminescent imaging.

October is the annual breeding season, "the rut" for the largest denizens of New Hampshire's North Country: Moose.  It's also the annual moose hunting season.

Following the initial recovery of moose populations, an annual moose hunt has occurred since 1988. That first year, 75 permits were issued for a three-day hunt in the North Country only. Last year, 400 moose permit hunters took 290 moose.

This year 275 coveted moose hunting permits were awarded by lottery from among more than 13,400 applicants for the nine-day season.

Threats to forest health from three exotic insect pests including Hemlock Wooly Adelgid, Asian Longhorn Beetle and Emerald Ash Borer loom large over the vast forests of NH. The veritable insect rogues gallery is at our doorstep after killing trees in nearby states.

Mayfly Ballet

It’s not just anglers who follow emerging mayflies. The drama plays to appreciative audiences above and below the water. Hatching nymphs rise from dark, watery depths up to the wide blue sky, a glorious curtain call and tolling dinner bell.

Dilig-Ant

The ants come marching, one by one, up the kitchen wall; it’s a sure sign of spring. These are the worker ants, females all, tasked with delivering food to the colony. Male drones remain in that colony, on call for their one role in a very brief life: mating with a fertile female destined to be a new queen.
