Friend!
Syrphid fly or hover fly larvae are voracious aphid eaters. You can identity the larvae by a faint line down its back. The fly itself feeds on nectar rich flowers such as dill, cilantro, sweet alyssum and yarrow. She lays her eggs among the aphid larvae. So don’t squish aphids- you might be swishing your friends!
