Re: Invasive Species B/C
Hi guys! I'm having trouble identifying species because so many of them look alike. I'm making a document on which species look like. Which species do you guys most generally mix up?

Re: Invasive Species B/C
Last year at states I screwed up hydrilla and brazilian waterweed, realized 10 minutes before the event that my ID pics for the two species looked like the same, but if I had made better notes that wouldn't have happened.

Re: Invasive Species B/C
It's mostly similar-looking generic (yeah, I went there) grasses, maybe the beetles. I don't have my comparison documents on hand to see what else, but there were probably some larval stages of insects that got lumped together, at least for quick on-the-spot comparison.RareKyurem wrote:Hi guys!

- the two pine shoot beetles
- the two longhorned beetles
- the two mussels
- giant vs common reed
- the milfoils
On the Pennsylvania list:
- the honeysuckles.......
- the knotweeds
If you are making an ID guide, make it like a dichotomous key, have all the warm-colored flowers on one page, all the pointy leaves on another page, etc.

-whitetop, hairy whitetop, giant hogweed
-some of the thistles look pretty similar
What two pine shoot beetles? As far as I know there is only the common pine shoot beetle (national list). Are you talking about the spruce bark beetle by any chance?

Re: Invasive Species B/C
I think the two pine shoot beetles are the Common Pine Shoot Beetle and the European Spruce Bark Beetle. How do you tell the difference between the Asian Long-Horned Beetle and the Citrus Long-Horned Beetle?dragon_fruit35 wrote:AlsoRaven wrote:This is going by the Nationals list:Skink wrote: It's mostly similar-looking generic (yeah, I went there) grasses, maybe the beetles.

Re: Invasive Species B/C
Sorry I replied two years late, at least this will help others. The USDA provides an accurate map for the distribution of Invasive Species.gryphaea1635 wrote:Is there a website where I can find up-to-date distribution maps? A lot of maps I've found online have conflicted with each other.

Re: Invasive Species B/C
CLB has a rough/bumpy elytra(pretty much a shoulder for wings), while ALB has a smooth elytra. If they just give you a blurry google images pic with an angle where you can't tell, good luck. If that's the case you may have to rely on having a lot of pictures of each in your binder in hopes that they match the picture you're given. A good ES will know these differences and be able to provide a good picture, but that won't always happen.RareKyurem wrote:I think the two pine shoot beetles are the Common Pine Shoot Beetle and the European Spruce Bark Beetle.
