Proceratium silaceum, or the Spider Egg Ant, is one of the strangest ants in North America. These ants build small colonies in wood and rocks, and feed exclusively on spider eggs, although they may be able to eat eggs of other arthropods as well. Queens are small, from 3.5 mm to 5.5 mm, with slightly smaller workers, from 2.5 mm to 3.5 mm. These ants should be kept between 20-25 degrees with humidity levels of 70%-80%. It is interesting to note that the workers of these species have no eyes due to their subterranean lifestyle. In order to culture these ants, the rearer should keep a culture of spider eggs, with the American house spider being a good option. Eggs should be fed to the ants before they have progressed more than a few days. It is theorized that the ants are able to inject spider eggs with a "preservative" so that they can be consumed for a longer period of time.

We do not recommend this species for beginners

Test tube inserts are upgrades to the test tube setups provided. If purchased, they come with a dark hood to lower light levels for the colony, an insert which provides a living space, and a feeding insert to provide food for the colony.

Ungrouted inserts are a blank plastic insert which helps provide a more suitable space for the ants to grip (as opposed to glass tubes), while grouted inserts are bedded with a substrate which helps distribute humidity more evenly throughout the test tube, and helps certain ants create their cocoons more easily. Overall, grouted inserts are more comfortable for the ants.

You will NOT need an insert for colonies in test tubes, but it does help for certain species. IF you are moving the ants into a nest immediately, do NOT get a test tube insert.
