Did you find these in a swimming pool or just walking around? I've caught plenty of T. caespitum, of course but I'm interested in keeping T. tsushimae. Are the queens bicolored and smaller, as well?

[cpman]

In the past week, I've seen Pseudomyrmex gracilis, Crematogaster laeviuscula, an introduced Tetramorium sp., Solenopsis invicta, and S. geminata fly.

Temperatures have been mid to high 90's, humidity between 40 and 80%. Only a trace of rain.

Walking around. I've measured about a dozen of these queens and they're all about 6mm, or just under a 1/4". I believe that's a bit smaller than T. sp. E is on average. Color wise they're a pretty uniform blackish brown color.

Interesting; I didn't even know they flew, I thought it was all in-nest breeding. I'll keep an eye out for these, I know there are a couple colonies near where I live. Are you sure this is not Temnothorax longispinosus or T. amricanus? Regardless, some photos would be nice so I know what to look out for.

I agree; It seems odd you are finding T. tsushimae in abundance. You sure it's not just caespitum/sp. e?

I have some Temnothorax longispinosus queens, so I know that's not them. I'll put some photos in the Midwest anting thread later.

I'm in St. Louis, which is the origination point for T. tsushimae in the US and from what I've read they've replaced T. sp E here and in the surrounding areas. I've measured workers and queens from several different colonies and they're all more in line with T. tsushimae than T. sp E. The other factor that seems to confirm that is that I've never found a non-polygynous colony of Tetramorium around here. You can lift up a rock and find several queens just sitting there. I don't believe that's normal for T. sp E, whereas T. tsushimae is known to be a primarily polygynous species. There are some extremely minor anatomical differences between the two species, but I lack the expertise and photography equipment to properly scrutinize that.

Species: Tetramorium caespitum

Location: Dracut, Massachusetts

Date: 6/22/17

Time: 5:00 AM (got outside at 5:00 AM so flight was probably going on before that)- 5:30 AM

Temperature: 74° F

Humidity: ~85-95 %

Wind: 8 mph

Rain: Might have rained earlier that night or morning...

 

This was a small flight, and only found 1 dealate and about 2-3 dozen alates.

Species: P. subnitidus, S. xyloni, S. molesta, L. alienus

Date: 6/25/2017

Time: 6pm-9:30pm

Temperature: 93 F

Humidity: 17%

Wind: 6mph

Rain: No recent rains

 

All of these were found blacklighting except P. subnitidus, which were running around everywhere. I collected quite a few. They are similar to P. californicus but are a tad larger (according to Drew) and have spines.

This afternoon, Solenopsis invicta flew.
Also, a Pheidole flew (I only saw males, so I couldn't tell you the species), but I suspect that was early this morning.

Last night we had 1" of rain, and it is 87°F with 60% humidity. It got down to 73° last night.

Austin, TX

 

EDIT: Crematogaster laeviuscula and Brachymyrmex patagonicus flew as well.

In Austin, today we had quite a few flights.

Last night we had around 1.5" of rain. Today, it's 89°F with 62% humidity.

We've had a little brown ponerine fly (Hypoponera opacior -- given the one jointed palps and thin petiole), Solenopsis invicta, and two different Pheidole -- neither of which is the one that flew yesterday. There were probably a handful of item flights, but that's all I found in my pool today.

Temperatures have been mid to high 90's, humidity between 40 and 80%. Only a trace of rain.

I've since confirmed that this Tetramorium that flew on the 22nd is T. bicarinatum, like I suspected it was.
