The bristly spikes of hair of this Tachinid Fly come form rings of tufts around its plump, red body.
Tachinid Flies look menacing, but they are harmless to people. Adults are often seen taking nectar from flowers. A fly larva, or maggot, does not drink from blossoms. Instead, it latches onto a pest insect that feeds on the same garden plant. This parasitic attachment leads to the death of the food pest, allowing the grown larva to pupate into its adult form. Generally, the insects that a Tachinid Fly larvae eats are known pests for gardeners that eat a plant's leaves, weakening the plant. Because Tachinid Flies are a natural biological control, they are beneficial insects.
