I want to make an ant farm from a small aquarium I bought, but I need an ant queen. I don't want to dig up an existing colony. Would having a queen overpopulate the colony? How would I find a queen after its mating flight? I live in Arizona and it's October. I've heard that you need to look for a small hole with a small pile of dirt by it. I haven't seen any. Will ants make a larvae turn into a queen if there is no queen present like bees do? What time is mating season for ants in Arizona? Should I wait until mating season starts? -Austin
Thanks for contacting us! Digging up a colony to find the queen can sometimes be very hard. Often, the queen is hidden very deep in the soil and you might not find her. It might be easier to wait until next season for a newly mated queen.
James Trager has shared his expertise on the times when to expect newly mated queens of some ant species that are encountered in Arizona and are fun to keep in a formicarium. Here is his advice:
Higher altitude, forest species of Camponotus fly on the first really warm days of spring, typically in April, May. Lower altitude species of oak-conifer woodlands, mesquite scrubland and true desert mostly fly with the first monsoon rains.
Finally, Formica species fly in July, especially early in the month, except the really high altitude ones, which may wait till August."
Here you can find more information on the ants of Arizona.
A queen would not overpopulate a colony. It is usually a good idea to have a queen, so that your ant colony lives past two month. The workers often die after this short time period and a queen would always supply new workers. Some of the larvae will turn into new queens, but they need to mate before they can lay fertilized eggs. It is very hard and often impossible to have ants mate in captivity. So it is best to find a freshly mated queen. You should keep your eyes open for several winged ant queens and keep one individual each in a small container. If one starts laying eggs, you can carefully transfer her to the bigger aquarium.
Good luck with your ant farm!
