Can you buy a queen ant?

Could you elaborate on the feasibility of purchasing a queen ant? I'm curious to understand if this is a practical option for those interested in ant colonies or entomology. Are there specific breeders or suppliers that offer queen ants for sale? What are the considerations one should make before making such a purchase? Do they require special care or handling? Are there any legal or ethical considerations to be aware of? Your insights into this matter would be greatly appreciated.
