Availability- We’ve recently increased our production of hydei flies to help make this product more often available, so we should be able to more reliably offer it.  Unfortunately, our production of melanogaster flies is largely consumed by our own frogs here….we are looking at ways to increase the supply of the melanogaster as well, however for the moment, if those show as out of stock,  we can usually replace a single cup of your order of 2 or 4 hydei “cup o’ flies” with melanogasters, just request this in the message box while placing your order.  In the event that we cannot fill this request, we’ll provide a producing melanogaster fruit fly culture instead.  Thanks!

As always Hydei “Cup O’ Flies” are limited so these requests are subject to availability.

Fruit Flies and Fruit Fly cultures are quite sensitive to heat, and unfortunately we can’t control what temperatures your order will be subjected to. When the weather is warm, there is a chance that your order will be subjected to high temps at some point in its trip to you, in particular as the box routes through the hub city, it can be outside in the afternoon, on the day after I send it. This is usually the culprit when I have DOA flies (which is actually fairly rare). Another potential problem can occur on the last leg of the journey to you, if your area is hot, and they spend all day on the FedEx truck, this can lead to them being overheated.

Since so much of the shipping process is out of our control, we generally do not offer any live arrival guarantee on Fruit Flies. However in general I am willing to reship orders if you pay for the shipping. You can find more information on how to avoid issues on our detailed Live Arrival Guarantee and shipping tips page.
