Plant-Insect Interaction: Syrphid fly on Queen Anne’s lace

Syrphid fly (Eristalis arbustorum, Syrphidae) feeding on Queen Anne's lace (Daucus carota, Apiaceae). Photographed 07/13/10 near Clayton Michigan.

Syrphid flies like the one above (Eristalis arbustorum, Syrphidae) are also known as flower flies or hover flies.  Many bear a superficial resemblance to bees (Apidae), but the one shown here looks more like a horse fly (Tabanidae) to me.

Despite their Batesian mimicry of venomous and biting insects, syrphid flies are generally harmless or even beneficial to humans .  Adults feed on nectar and many serve as important pollinators.  Some larvae feed on aphids and thrips, which are highly damaging pests of agricultural plants.
