Asian Longhorned Beetle Identification

I was glancing through your website just curious and I noticed that the information on the Asian Longhorned Beetle was inaccurate. The photo was inaccurate also. So I thought I would just send the accurate info with a few photo's. You see I work on the Asian Longhorned Beetle Eradication Program and the states that have current infestations are New Jersey, New York, with eradication already declared in Chicago, IL. This beetle has also been detected in Canada and Germany and they are following our lead in the eradication process. This beetle is very destructive and can change our land scapes and canapy's as we know them. They kill several species of hardwood trees. Elms, Willows, Maples, Chestnut etc... They just don't eat a little and then move on, they kill the entire tree by leaving sometimes 100 exit holes about the size of a dime throughout the tree killing it. Thousands of trees have already had to be treated and or destroyed with replacements done by the forestry dept. and the state. Central Park was saved by this program and is being monitored very closley. I will try to post some pictures so the incorrect information and photo's may be replaced. Remember if anyone identifies this beetle please notify the USDA, Plant Protection and Quarantine dept.

I will try to post some pictures in the photo section.



More info for everyone.

The Asian Longhorned Beetle in the United States

The Asian Longhorned Beetle (Anoplophora glabripennis) (ALB) is an invasive insect from Asia that traveled to the United States (U.S.) probably contained in solid wood packing material like the crates and pallets used to import goods. The ALB larvae bore deep into deciduous trees such as maple, birch, horsechestnut, poplar, willow, elm, and ash eventually killing the tree. If the ALB were to reach the urban and suburban forests of North America, approximately 1.2 billion susceptible host trees would be at risk. Potentially, this could add up to $669 billion in losses and impacts to such valued commodities such as timber, maple syrup, nurseries, and tourism.

The ALB was first discovered in 1996 in the Greenpoint section of Brooklyn, New York by an alert resident. The U.S. Department of Agriculture’s Animal and Plant Health Inspection Services, ALB Cooperative Eradication Program (ALB Program) has been operating since then to protect the biological diversity of our hardwood forests, parklands, and the quality of the urban environment from ALB infestations in the United States by eradicating this destructive ALB pest from the U.S. As of September 2006, more than 32,000 trees susceptible to ALB infestation have been removed from the U.S. to halt the spread of this invasive species.

ALB infestations have lead to Federal quarantines in sectors of New York, New Jersey, and Illinois. These states are where the ALB Eradication program’s safeguarding efforts have been concentrated. Through survey, control, and regulatory compliance measures, coupled with increased public awareness, the ALB Program protects trees. Over the years the program has made steady progress in its eradication efforts.

In 2006 the Federal and State quarantines in Chicago was recently lifted through a deregulated action. Quarantine zones in Hoboken and Jersey City, New Jersey were deregulated in 2005. In New Jersey, new pockets of infestation were uncovered through ALB Program efforts in the Middlesex/Union County area. The new discovery of infested trees prompted an expansion of the New Jersey quarantine from 16 to 25 square miles in summer 2006. The ALB program’s efforts have also led to the discovery of infested trees in sections of New York including Queens, Brooklyn and parts of Long Island in recent months.

One of the ways this wood-boring insect travels is by human transport as people move firewood from place to place while camping and vacationing. The ALB program urges people to refrain from moving firewood out of ALB quarantine areas. Travelers should buy firewood where they camp, hunt or vacation so they do not inadvertently move this pest to new regions and put more trees in danger.

While On The Subject...
...another longhorned beetle causing similar concern, but up in Canada, is Tetropium fuscum, the brown spruce longhorn beetle. No images posted on this site yet--not surprisingly, since it's a relatively new introduced exotic confined to Nova Scotia thus far--but it's one worth watching for. The image below is of a male, the one with the longer 'horns', and don't worry about copyrights. It's a government-supplied image and the people who provided it will be only too happy to have it more widely publicized.

In a nutshell: This insect was first positively identified in a heavily forested public park in the city of Halifax in the spring of 1999; that 'intro' date was later pushed back when it was discovered that specimens collected in 1990 and erroneously identified as a similar, native species were in fact the brown spruce exotic. Initial attempts to contain the beetle included the sacrifice of thousands of apparently infested or at-risk spruce trees within the city limits and the establishment of a 'watch' zone in outlying districts (forestry officials diligently surveyed everyone's property within the zone that summer, including my own, and set beetle traps). The efforts failed and this beetle is now thought to infest half a county's worth of territory about the initial collection point. It's quite the expansion for less than two decade's worth of known residence!

And if you're wondering by now why I hijacked this thread and am wasting a post about an insect with such a limited range, it's because it's believed that this beetle probably entered Canada via the packing material inside shipping containers unloaded at the port ie. the exact same scenario which allowed for tucker1347's longhorned beetle's immigration. In fact, for all we know, maybe the brown spruce longhorn beetle is settling in round about some other Eastern seabord city right now. So--just another one of those species for all you sharp-eyed photographers and collectors to tuck away in the back of your mind and watch for. Tracking the appearance and spread of introduced exotic insects is something any interested naturalist, even an amateur, can really contribute to in an important way.

BSLB pic
I have a Canadian Forest Service calendar which contains an image of the BSLB almost (but not quite) identical to the one above. These images are by Klaus Bolte. I quote from the back of the calendar:

"During his 39-year career as a technician with Natural Resources Canada's Canadian Forest Service, Klaus Bolte pioneered the photographic technique used to capture these insect images. Using a digital camera mounted on a microscope, he photographed individual insect parts and re-assembled then electronically to produce a detailed, in focus image of the entire insect."

I am involved peripherally on the BSLB problem here at CFS. I have some images (not very good ones) of this critter. I will try to get permission to send them in, then someone can create a new page.

would be a worthwhile addition

Phillip, Here is a link fo

Here is a link for inclusion in the new BSLB page.

I have permission to send in images and I will insert them (5 in all) to this page, together with photographers' names. These are images that have been used before in posters, web pages, etc. I can't see how I can create a new species page, so you will have to do it.

Post them on ID Request, make a note of the name and someone will make a page for them

you have permission and know who owns the rights to the above image, go ahead and submit it, taking care to fill in the copyright block. Without a page, this forum item will get overlooked by the vast majority of users. I'll create a page and copy your info over to it.

We seem to have two by that name:
1. Sybra alternans (Asian Longhorned Beetle), which has nothing to do with the one you're interested in:
2. Anoplophora glabripennis - Asian Longhorned Beetle

We can correct the erroneous information, but you'll need to be more specific about where we're wrong.

Also, I noticed that you posted your images on the Coleoptera order page. If you are indeed qualified to identify this species, you should have posted them on the image page for Anoplophora glabripennis. Feel free to move them to the correct page, or we can do it for you

I apoligize, I am very familiar with this beetle, but I am not familiar with how to navigate through webwsites such as this. I kinda stumbled across it. Please move the scientifc information where ever it is supposed to be as well as where the photo's should be. This beetle is very rare in the US. I just thought people might be interested.

Thank you, and I really like your website.


I've deleted the common name "Asian Longhorned Beetle" for Sybra alternans [couldn't find an accepted common name], which as Chuck noted has nothing to do with the one you're interested in and could be confusing, but there is absolutely nothing wrong with either the info about or existing picture of Anoplophora glabripennis - the beetle commonly referred to as the "Asian Longhorned Beetle". Images should also include date and locale info - please update your submissions - I moved them to the correct page, and copied the above info. The guide page for the 'real' ALB was added back on 1 June, 2005. I would be amazed if we had got this wrong - a quick Google search produced over 200,000 hits - someone would have noticed before now!!

Do you own the copyright to the images you submitted? They seem to be on other websites already - this is similar (same?) as this one [middle of page], while the other looks like this.

Not just similar
Both pairs are identical except for scaling and cropping. The second one is labeled: "Photo credit: APHIS photos by Ken Law"

not trivial concern
many websites have gotten into significant legal trouble hosting copyrighted material without permission - don't know if this situation applies. I didn't see anything in the BG guidelines addressing this issue.

It's addressed
On the upload page it clearly states that one must get approval from the copyright owner and give attribution. Of course, there's lots of verbiage on the page, so it might go unnoticed.

In the case of the second image, though, it might not be a legal problem, since it's provided by a US government agency for public use. It's possible that the other one is from a similar source- or she might even have provided it to the other site.

Intellectual property issues are crucial to the very existence of this site, though, so we should bend over backward to do the right thing. Without correct attribution they should be frassed. I'll correct the attribution for the APHIS one for now, and we can discuss what to do next.

both on MANY websites
I did a quick Google image search and both images appear on several websites - in various articles about the ALB, the first image is credited to: USDA, Dennis Haugen/USDA Forest Service on one of those. This may not be a legal problem, if properly credited, but I don't know if BG wants to start posting public domain photos for their educational value - maybe we do, but probably not? At a minimum though, they need be credited to the photographer.

You're right, on the image submission page, under copyright;
"Leave this blank if the image is your own. If the image is not your own you must get permission from the owner before submitting it here. If you have permission, specify the copyright owner's name here."
