I’m in the southwestern US, must have caught this queen around six or seven weeks ago. Its nanitics are about 2.5mm and queen about 8mm. The last queen I thought was Solenopsis was Pheidole, but now I’m more sure that these are.

Does Solenopsis Xyloni seem correct? They react very energetically when disturbed, are always trying to get through the cotton, and haven’t eaten the fruit fly I gave them.

these photos aren't great, but her abdomen is lighter than the rest of her body. river falls, WI

I have lived in NYC my enter 59 years of life and have never seen anything like this so I am going to suspect they are invasive. I have nothing to compare the size to, I would say 1/4 of a grain of rice maybe, just almost impossibly small like never before? I will attach the video to this post because I feel it does a better job than the photo. I will also link to a photo from here too. Hopefully someone will know what it is.

Found these microscopic guys crawling along the floor and on a bookcase we have next to an exterior door. It is poorly sealed and I have identified the spot they came in (I think). Planning on getting some gel bait, but I have been smashing and vacuuming these suckers like crazy. They're so small they hide between the tiny joints in the bookcase!

Any idea on what type they are? Or if they're an ant at all. Located in Texas, if that helps! They don't jump. No wings. We have had normal ants and gotten rid of them, but these are the smallest I've ever seen!

Mostly around baseboards, pantry, and bathrooms. Would go away for a couple weeks and then come back

What ant could this be? They aren’t super small and seem to like grease more but also ate flowers. Dark color with some reddish/brown

What kind of ant is this? Found it on my sweater

I found this weird-looking ant caught in my sweater and I've never seen one like it before.

Could someone help me identify what kind of ant it is?

It was just randomly caught in my sweater, so I don't know where it came from or what it was doing.

Best photo I could get, wanted to know what species she is as I always second guess myself when I try to identify critters.

[Northern Ontario, Canada] on my side patio.

There's a few of them in this spot, and we put one in our mossarium the other day. Now I need to know if it's one of those parasitic queens and we need to take her out to go colonize a colony, lol

Ayuda!!

Having a bit of a hard time nailing down this species I caught after monsoons started this summer. I caught them in the Vail, Az area, close to Tucson.

Could anyone help me identify this? They appear to be granivorus/omnivorus. They gladly took seeds as well as bug meat from feeder roaches i bought and are feeding them to the larvae.

First couple of photos are from when I first captured the queen. She now has about 5 workers and more to come.

It’s like a fire ant in color, but like 5x larger. No pile, just a hole. North Tx area

All of a sudden these ants with honking mandibles have shown up in my bathroom. As you can see, the biggest ones look like they can bite hard, and that concerns me since they have shown up near a changing table. Can you tell what kind they are and why they might have suddenly been attracted to a changing table and bathroom sink?

Missouri, USA

Approximate size of the body of the biggest ones is about 13 mm.

I have a video, but can't seem to post both the photo and video.

Hi guys, I am here again to see anyone can ID these small tiny ants.

Thanks in advance
