| "Bear Swamp," PA Posts: 876 | Jason, As far as I know, the only species of Paragnetina we have in NY and PA are media and immarginata. The latter, the "beautiful stone," is highly patterned in yellow/black/brown and has very distinctive markings. So, even though the markings on this specimen seem somewhat unusual for media, I'd have to go with an "embossed stone" ID. Were it not for what appears to be a complete setal row across the occiput, I'd be inclined toward Acroneuria. | |

| Posts: 6 | Guys, I have noticed that several of the pictures on this website are mis-identified. This set of photos is not of Paragnetina at all. There is clearly no occipital ridge. It is true that the only species of Paragnetina found in the State of NY are immarginata and media, but this specimine is clearly Acroneuria sp. I am also from NY and I am a NABS certified taxonomist. My company offers macroinvertebrate taxonomy workshops for professionals. If anyone is interested in improving their ID skills, have a look at the "Upcoming Workshops" tab of our website. Also, feel free to contact me directly and I'd be happy to point you in the direction of some useful dichotomous keys.

| Fairbanks, AK Posts: 1115 | Thanks Matt. Please post correct IDs on any specimens you find misidentified, if you've got time. That's why I built the forum into the main site the way I did, so experts can weigh in on such tricky business. | |
