At Polyfly, we produce several hoverfly species and currently commercialize two from the Eristalinae subfamily—generalist pollinators highly effective across a wide range of crops:

QUEENFLY® (Eristalis tenax)

• Ideal for temperate, cold, and cloudy climates.
• Active at low temperatures (between 10 °C and 30 °C), where bees and bumblebees reduce their activity.
• Excellent choice for spring and autumn crops.
• Commonly known as the “drone fly” due to its resemblance to honeybees.
• Effective under low-light and overcast conditions.

GOLDFLY® (Eristalinus aeneus)

• Specialized in warm and temperate regions.
• Active between 16 °C and 36 °C, even tolerating temperatures above 36 °C.
• Ideal for spring and summer crops.
• Golden body and spotted eyes make it easy to identify.
• Performs excellently under high temperatures and variable light conditions.
