The beginning of the summer I ordered two queens and two interposer sets. All arrived perfectly fine. The following images are from about a month ago. This review ended up a bit delayed, oops
The two queens are Camponotus pennsylvanicus and Crematogaster cerasi. I'm located in Michigan, so I could purchase queens
The queens and workers looked perfect in their little test tubes. There was a bit of mold in with the Crematogaster but that was removed and no longer an issue. So no issues with the ants They are enjoying honey water, sugar water, and fruit flies.
The interposers are wonderful. They make it a lot easier to manage and feed the colonies before they get very large. The little feeders make it so you can leave them alone for a while longer than if you are using just a cotton swab dipped in honey water. They do work with different test tubes. For small glass ones, I put some rubber hose in the connector, and then into the test tube. For the larger plastic test tubes, you can just put the connector right in the tube.
I'm glad I ordered. There wasn't really any negative experiences with the order, and communication happened relatively quickly through Facebook. I ordered during the 117Colonies website renovation, and so I ended up with a question or to. Handling time was a little on the longer side, but nothing terrible.
