Field Notes
Description:
Toxomerus geminatus are small syrphid flies, about 5-10 mm. Syrphid flies also known as hover flies or flower flies are especially beneficial because the larvae are predatory, feeding on aphids, small caterpillars & thrips. A single larva can consume up to 400 aphids during its development. Adults take nectar and/or pollen at flowers and are considered light pollinators.
Habitat:
Toxomerus geminatus is found in eastern North America only. Open areas with flowers.
Notes:
Please consider not using insecticides for aphid infested areas. Even insecticidal soap which generally will not harm adult syrphid flies, can be very disruptive to their soft bodied larvae.
