- What's a Test Tube Insert?
- Shipping Conditions
Formica ulkei are thea large variety of Formica which live in Canada. These are the largest of Formica with queens from 10-13 mm and workers from 6-10 mm. Mature colonies will accept new queens, becoming polygynous and allowing them to grow extremely large colonies up to 100,000 workers in 10+ years. They prefer 22-26 Celsius and like around 50% humidity, though there is slight variation across species. They're more skittish than most ants, and so are of medium difficulty to start, but are extremely enthusiastic and fast growing once they break 50 workers. In the wild, Formica ulkei are the most dominant ants in their area, hunting down other species and consuming large amounts of biomass. We get many of these each year, though the numbers are variable. Note that this species requires good ventilation, or their formic acid spray may become an issue.
***We offer polygynous colonies of this species, which can be bought on special request
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.
