In other species, the larvae are insectivores, preying on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered crop pests, so the aphid-eating larvae of some hoverflies are economically and ecologically important. The larvae are potential agents for use in biological control, while the adults are pollinators.

[8] [13] This larger abundance of food is very beneficial to the crab larvae. On ...
