Tachinid
flies act as a natural check to many plant-feeding insects, which could
otherwise do great damage agricultural crops. Larvae of these Cylindromyia
flies are lethal parasites of Heteroptera or shield-backed bugs, which
damage orchard fruit such as apples and apricots. Adult Cylindromyia flies
live on nectar from summer flowers such as buckwheat
and rabbitbrush;
thus, these plants support egg-laying by these beneficial insects. Cylindromyia
flies mimic wasps in form and color,
which likely helps them survive as adults.
Other tachinid flies seek out cutworms, loopers, cabbageworms,
armyworms, among an extensive menu of plant-attacking beetles and bugs.
The economic benefit provided to agriculture by tachinid flies is tough
to estimate but certainly enormous.
