We currently sell fruit flies (Drosophila sp.) exclusively as preorders, and are working on adding a subscription function. Once you have placed your order, we will make a new colony and only deliver it once it is properly established (usually within 3–4 weeks). This allows us to guarantee the highest quality on our colonies, while also making sure that you will always have fresh colonies that will last for a while! If you want to have fruit flies ready to go the entire month, we recommend ordering one colony for about 4–6 frogs (depending on species) every week.
