I'm new to this website, so forgive my dumb question. What should I tag them as?

You can get a lot from the Help page, it's worth looking at. Here's what you can do now: Open your post, like this, and just above the thumbnail images you'll see the words "tag all". Click on that and you'll see all the images on the left side of the web page. Then navigate to the page where you want to move them (navigation can take a while unless you're a bug expert). For these specific images you could just click on this: http://bugguide.net/node/view/5234/bgimage and that will take you to the Laphria root images page.

For unknown Laphria you go there and click "move tagged images" and it will move your "tagged" postings there. Then the robber fly experts are more likely to see it/them. You might even want to just move them to the Asilidae root page. I'm not positive where they're more likely to be seen but I'd go with Laphria for now.

There are different ways to navigate to a species. You could use the Taxonomy page to start with and when you drill down to the species you want, you then click the "Images" tab and you can either post new photos there (add image) or tag and move images like you're going to do now.

I hope that helps. It took me a while to figure out what works best for the experts and I still have more to learn. Others have helped me out a lot with their suggestions, too. A lot of us on here are beginners.

I think I did it! Thanks for the help!
