And now, a public service announcement.

While I am flattered that many of you use my photo galleries to identify mystery ants, please be aware my site has limitations as a diagnostic tool. In particular, I am missing a lot of species, even some common ones, and even in North America.

Of the 33 North American species of the common genus Lasius, I have only 11:

That’s typical. Here, as an additional example, is how I am faring with Pogonomyrmex harvester ants:

Thus, when browsing my galleries looking for a match, bear in mind there’s more diversity than what I’ve posted. Often, much more. I’m just a guy with a camera, and progress happens only as time and budget permit.

If you’ve got ants needing reliable ID, you’ll do better consulting a site designed for species diagnosis like Antweb.org. Or better yet, use the primary literature.
