State forestry and environmental officials want photos of invasive insects

New Hampshire welcomes a lot of visitors in the summer, but there are a few they don’t want to see cross the border.

And officials are hoping anyone who spots these unwanted guests snaps a photo and sends it in.

At the top of the wanted list are the Asian longhorned beetle and the emerald ash borer.

Neither destructive insect has been found in New Hampshire, but forestry and environmental officials are on the lookout for a potential invasion — and they want residents to do the same.

There’s a website, nhbugs.org, where residents can upload photos of suspicious insects. Experts will identify the bug in question and post the more interesting photos on the website. There already are dozens of photos up, many of an Asian longhorned beetle lookalike — the white spotted sawyer beetle, harmless and present throughout the Granite State.

The Asian longhorned beetle, commonly known as ALB, was found in Worcester, Mass., in 2008 and in Boston in 2010. It has the potential to decimate hardwood forests and maple trees are high on the list of susceptible trees.

The insect could cost the country 30 percent of its hardwood trees — some 1.2 billion trees, according to the USDA’s Animal and Plant Health Inspection Service.

New Hampshire has 2.5 million acres of northern hardwoods — birch, beech and maple trees, according to Fred Borman, a forestry educator with the University of New Hampshire Cooperative Extension office in Brentwood.

The emerald ash borer is equally unwelcome. It is only interested in ash trees and has killed millions of those trees in the Midwest.

There was a report earlier this year of a small population of emerald ash borer on the east side of the Hudson River in New York, Borman said.

“It’s a matter of time. The emerald ash borer has a much faster spread rate than ALB,” he said. “Adult females tend to stay on same tree until the tree dies, about five to seven years. Emerald ash borers, both male and female, are very food fliers and they will travel up to 2,000 feet to find a new host. ALB are lay fliers.”

There’s a third insect that concerns forestry experts — the hemlock woolly adelgid, but it’s already here.

“We’re at a point where we’re monitoring it; we can’t control it,” Borman said. “We hope for a really cold January.”

August is a particularly active time for ALB and they might be found in an unlikely spot — swimming pool filters.

After ALB was discovered in Worcester, a public swimming pool worker told experts he had been collecting the nasty beetle for years in the pool filters.

Education and awareness are key to combatting these unwanted insects, according to Karen Bennett, a forestry specialist with UNH Cooperative Extension.

“Look at your trees all the time, year round. Be skeptical, if the tree doesn’t look good, ask someone,” Bennett said. “We really try, through the website, to make it easy for people. Take pictures of suspected .insects. We have an entomologist who looks at everything and gets back to folks.”

Adult insects would be active now through the end of August, she said, and if they’re here, they’d be flying.

“I have reason no reason to think they are, and no reason to think they aren’t,” Bennett said. “We really don’t know and that’s part of the frustrating thing.”

But experts do know the hemlock woolly adelgid is here and spreading through Southern New Hampshire.

“Extreme cold keeps them under control; it definitely depresses the population,” Bennett said. “This past winter was anything but.”

Asked to rank the unwanted insects, Bennett said, “They’re all pretty bad, as far as I’m concerned.”

“Anybody interested in white ash would rank emerald ash borer as the worst threat because you have dead trees in a short period of time,” she said. “But, in the overall scheme of things, ash is a pretty small percentage of our forest. I personally think the emerald ash borer is potentially worse than hemlock woolly adelgid or ALB.”

But all non-native insects are cause for grave concern, she said, because they don’t have natural predators.

So, experts are counting on the public to remain vigilant and help them keep tabs on the state’s insect population.



What to look for:


Asian longhorned beetle:
It's large, between 0.75 and 1.25 inches long. It has very long black and white antennae. The beetle's body is glossy black with irregular white spots.

Emerald ash borer:
The metallic green adult beetle is about an inch long. Its body is bullet shaped.
 

Hemlock woolly adelgid:
The adult adelgid is reddish-purple and only about 1/32 of an inch long. It's usually recognized by the dry, white woolly substance it secretes. The mass is usually found at the base of needles and resembles the tip of a cotton swab.





A morning walk on the Windham NH Rail Trail

It was a great morning for a walk! I decided that the Cocker needed some exercise so she could shed some of her hair in the outdoors instead of in the livingroom.

At the beginning of our walk at 8:05am it was a cool 67 degree's and not a soul was on the trail. As we began our walk onto the trail it was evident the birds had been fluttering about undisturbed and uninterested in us adventuring in there playground.

Within minutes of the walk we were greeted by a pair of Downy Woodpeckers that were working on there tactical maneuvers diving through the woods from tree to tree chasing each other as if they were synchronized swimming. More likely it was a parent teaching it's young.

Further along the trail we passed through a section of the old railroad bed that had been cut through the ledge with great walls of rock on both sides of us. This area normally has water dripping from the stone and moss growing on the walls, but today they were only damp at best.

Signs of fall are already becoming evident as the leaves are beginning to fall and turn yellow and brown. Wear-as it has been so dry this summer it would lead one to believe the fall colors this year are going to be short lived as most are falling without any color.

The chipmunks and squirrels appear to be preparing for the coming months, as they are darting in and out of the trail collecting the acorns that are dropping from the trees.  It may just be my imagination but wildlife seems to be desensitized to human interaction.  They have no fear anymore of us and almost seem to be daring us to try and bother them.

At about the halfway point of our trip this morning as shown on the map below there are bodies of water on both sides of the trail.  Once again the telltale signs of a dry summer have become terribly obvious as the lily pads are choking out each other attempting to stay wet in the vanishing water.  The levels are down a good 12-16 inches below the normal levels this time of year.  The frogs are plentiful and everywhere in the shallows of the two ponds, and jumping from lily pad to lily pad without falling through due to the density of the pads.  In some areas the pads are so thick that they are pushing each other up out of the water.



Even with the drought conditions on the water the area was bustling with life.  While on site today there were a number of Belted Kingfisher's, Great Blue Heron, and Swallow's galore.  The Kingfisher's were scanning the ponds for small fish and the Heron's would call out to each other occasionally.

I was quite surprised that I did not see any snakes along the banks today sunning but it was a bit early and the sun wasn't very high in the sky.  Being cold blooded they lay in the sun to soak up warmth usually in the height of the sun.

There was no sign of the hawks that frequent the area, but that is probably why so many chipmunks could be seen.  They tend to stay in there boroughs when they sense they could be somebody's lunch.

There is always something to see along the trail, it is paved and is very accessible for bikes, wheelchairs, roller-blading, jogging, dog walking, and just plain walking.  More information can be found at:  windhamrailtrail.org

Get out and enjoy the weather while there is still time.  Fall will be here soon then old man winter will be knocking on our door.

Have fun!
