Crematogaster pinicola

 

Crematogaster pinicola is a bicolored species that is found only in the far southeastern states. In the wild they nest exclusively in pine trees, hence their species name. Other than their color and the trees they nest in, they are basically identical to C. ashmeadi which are all black. They also happen to be one of the most common Crematogaster species in Florida.

 

I've had this colony for a while and I've been meaning to start this journal but I kept forgetting. Here is how they've been growing since I caught the queen.

Now they have about 60 workers with a pretty good brood pile. They have a very good appetite and do not look like they will slow down anytime soon. Looking forward to this colony becoming large!

Nice colony! I have a founding C. lineolata queen. I'm hoping she does as well as your colony!

I have estimated the colony to be at about 90 workers now. There is a pretty big pile of brood, so I expect the size of the colony to double in the next two weeks or so. In the pictures it's not as easy to see the brood because of the white sand, creating barely any contrast with the brood. It's harder for me to take the test tube out of the outworld to get pictures because at this point they'll just swarm my hand. They are very active and kinda crazy.

 

I also want to mention that most of the workers in this colony are quite large. Like, larger than any Crematogaster I've seen.

The queen just laid more than 100 eggs. I'm getting ready to move the colony into a formicarium because they are about to outgrow this setup quickly.

Wonderful journal as always :)

You mention that the only difference between Crematogaster pinicola and C.ashmeadi is color, with C.ashmeadi being all black. I always thought that C.ashmeadi sometimes could have a reddish coloring, especially on their thorax. I actually have a colony of Crematogaster that I'm almost certain is C.ahsmeadi, but they are not jet black. They also aren't as red as the ants in this journal. Is it true that C.ashmeadi are all black? and is there usually a slight amount of variation when it comes to the coloring of Crematogaster ants even of the same species?

 

Thanks and sorry for posting a question on your journal, but I wanted to hear what you thought.

There are lots of different Crematogaster species in the eastern US, and a lot of them look almost identical. I've never heard of lighter brown or red ashmeadi but species like C. lineolata, cerasi, and pilosa that appear to be a lot more variable in color. Perhaps your species is one of those.

Nice to see you finally got a colony of these going. It's been so long since we've talked :/ You should make a video of these guys, too, I'd love to see that.

Probably about 200 workers now. I think there are still more pieces of brood than workers and there's still a huge pile of pupae. Some of the eggs being laid are likely trophic eggs to feed the larvae with. Yesterday I started moving the colony into their first formicarium, a Tar Heel Ants Fortress, and they're almost completely moved in now.

My Crematogaster ashmeadi are growing fairly quickly with 15 workers and over 150 brood. Any tips?
