Field Notes
I was spray painting with my step dad when this beetle flew right where I was painting and got some black paint on its back, but my step dad looked at it and said that it might be ALB, and hearing what my teacher had to say about it I knew it wasn't a good beetle. So I caught in a container and started observing it. The body is about 2 1/2 centimeters long and its antennas are about 2 centimeters long. It has a white spot right below its neck, and its neck goes out to a point on each side. It has six legs with a little gripper at the end of each. It has pincher like things around its mouth. It's also black

Supporting Evidence

It doesn't have white dashes on its antennas, and the antennas are shorter than the body.

ALB doesn't have the white spot right below its neck, but the White spotted Sawyer does.

In this picture the beetle fell on its back so I took a picture of its underside. It's hard to tell these beetles apart but I looked into it more and decided that it looks more like White spotted Sawyer. I sent this to some people and I think they agree.

Strong detailed analysis! Your measurements of the beetle and its antennae provide accurate quantitative data to show it is not the ALB. The photos from different angles are also clear and detailed. What following steps could you take to confirm your own identification? Great work!

I knew your submission was a winner this summer. Outstanding work Ledger2001. Congratulations and keep up the good work.

Your observation was a winning entry in the GMRI Citizen Scientist Challenge! Thank you for posting great data this summer. We hope you enjoy your contest prize which you should receive shortly.

Happy observing,
-Team Vital Signs

Thank you so much! It means a lot to me that you chose me!

I thoroughly enjoyed reading your field notes and supporting evidence for your longhorned beetle find. Your pictures are great, allowing us to see the white spot behind the thorax that indicates what you correctly thought it was - the whitespotted sawyer (Monochamus scutellatus). Your drawing is fabulous also. As you know, this is a native species and not considered to be a threat, unlike the Asian longhorned beetle.

Thank you for posting your observation. Mid-July thru October are the best months to spot the Asian longhorned beetle, so keep your eyes peeled.

Great job spotting this critter! I was away on vacation when your email came through, but I'm so glad you posted this to VS. You give lots of compelling evidence that we can breathe a sigh of relief... no ALB! I couldn't agree with sniffly more... you have the heart of a true scientist. I'm looking forward to the species expert reviewing your ID.

Keep up the good work :)

PS: great sketch!

Nice work, ledger2001! You are a keen observer, and a great scientist. :)


Way to go! First of all, good quick thinking capturing the suspicious bug to get the great pictures you did. Outstanding job picking out the differences. I think you are correct in your analysis. Thanks for taking the time to do this important work. Keep looking closely.
