Toxomerus geminatus
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.
Toxomerus geminatus is found in eastern North America only. Open areas with flowers.
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.
