Pro-Series Fruit Fly Media (Hydei Formula) - 1.5 lb Bag

Drosophila hydei are the marathon runners of the fruit fly world. Because they take twice as long to develop (20–25 days), they need a media that won't dry out or sour before the first fly even hatches. Our Pro-Series Media is engineered for long-term stability and maximum nutrient density.

The 1% Volatile Oil Cinnamon Infusion is critical for Hydei cultures, as it prevents the mold growth that typically occurs during their slower development phase. This formula keeps the media at the perfect "applesauce" consistency for weeks, allowing the larger Hydei larvae to thrive and reach their full size. Step up to the Big Leagues of fly production.

• Best For: Sustained production of large (hydei) fruit flies.

• Performance: Engineered for long-term stability and hydration.

• Yield: Makes 10+ standard 32oz cultures.
