Fine grade Excelsior Aspen shavings. These wood shavings are used in a flightless fruit fly culture to provide the flies with walking around room, as well as places for the larvae to pupate.  Excellent for Drosophila melanogaster, and will definitely improve your results with all variants of this fly.

For Drosophila hydei, this product or another similar product is basically mandatory, as the culture is not capable of supporting the mass of the hatching flies without the excelsior.  In the past we used coffee filters for hydei, but this product is superior, due to its ability to stay together and not breakdown into a ball of slime!

This product ships with our FedEx Second Day shipping, included in the price. This is a stand alone product, no other items ship with this product.  If you want to purchase your media with other items, go back to the product list and choose a different excelsior product.
