Tachinid Fly larvae are efficient pest controllers for certain moth species. This particular species parasitizes some tiger moth and skipper species. Because of this diet in the larval stage, some species of Tachinid Flies have been deliberately imported from other areas to control destructive moth populations.
A female Tachinid Fly will one or two fertilized eggs on or near a moth caterpillar. The caterpillar can inadvertently eat the eggs as it chews on the leaf the eggs were laid on. The larva may also latch on to a passing caterpillar and eat into its body. A larva will then feed on the caterpillar's internal parts until the caterpillar dies. The fly larva will move to the ground where it will dig a hole to pupate in. Flying adults emerge from the ground. Adults drink nectar.
This particular species of Tachinid Fly can be found on flowers, in fields, parks or gardens during the summer and autumn.
