C. reticulatum or C. discrepans? - Calopteron

C. reticulatum

My thanks to you Jennifer, and you, Joshua, for your past posts and great photo. I found this same beetle on the screen of a vacation condo in Bartlett, NH, this past week, and was looking for an ID online. The condo also bordered oak/maple woods.
What a great resource this site is!

Betting on reticulatum

Based on the characters currently cited on the Info pages (which have probably changed in the 13 years since you posted this photo!) I'd go with C. reticulatum.

Guide-FaceBook crossover

I know, don't you love when that happens? I was looking at the recent Calopteron post in the NE Insects FaceBook group, so came to BugGuide for reference, and called up the list of Calopteron records from MA, and just happened to stumble across yours that was still at the genus level....

Something similar - same team?

I have a picture of something similar that hitched a ride in from outside here in NC. How to post the image?

In case you didn't already figure this out in the past year...

From this page, scroll up and click on the "Images" tab. On the page that comes up next, just under the name of the insect will be a link that says "add image". Just fill in the blanks, as many of them as you can, and use the "Browse" button to select the picture from your computer's hard drive. Then click "Submit" at the bottom of the page, and you should be done, your image will appear on the Guide. (Note: if you're not really sure that your image is of a member of this genus, before you click "Images", you should click on the category to which you're sure the critter you photographed belongs, even if it's something really general like "beetles" or "insects")

Hope you get an answer

We have also been confused. Our understanding is that the central dark band is essentially uniform in width all the way to the edge in one species, while it gets narrower as it moves outward in the other. But it has been difficult get expert confirmation on this. Thanks for the beautiful image and for asking this difficult question.
