A couple weeks ago, I caught about 30 Tetramorium queens. I did not have enough test tubes, so I improvised and placed about 10 queens in plastic bags until I could get proper housing for them. I placed the bags into my desk drawer, and left them there for about 4 days. I got my hands on some test tubes, and I went ahead and started placing the queens into their new homes.
Here is the crazy part. I retrieved one of the bags, with a Tetramorium queen inside, and immediately upon disturbing the queen I could hear a strange squeaking noise. It kinda sounded like a mouse! I couldn't figure out where that noise was coming from, and then it dawned on me to put my ear up to the bag. To my surprise, the queen was making a repetitive squeaking noise! She made this noise for about 20 seconds, while standing still and waving her antenna.
Has anyone else experienced this before? It was seriously pretty cool.
