The green lacewings are quite hungry when they are in development, they have been known to eat over 200 aphids in only a week when in their larvae form.
The lacewing’s larvae will resort to cannibalism if there is insufficient food. Due to this immense hunger most green lacewings tend to lay their eggs near a colony of aphids so that when their eggs hatch, the larvae have a readily available supply of food. The green lacewing can be brought to your garden by growing some dill, angelica, coriander or dandelion.

Wrapping It All Together
It’s a good idea to learn the life-cycles and diets of both the beneficial insects and the pests in your garden. This will prevent you from accidentally ending up destroying the “good guys”.
Before fighting insects with insects, see if there are other natural ways to get rid of the invading pests. One good method is having plants that repel the harmful insects or some other way to get rid of them.
For example, sage can be used to repel cabbage moths and flea beetles. Therefore, it’s not necessary to introduce tachinid flies into your garden. A strong hose spray is usually enough to knock away most of the soft bodied insects.

Several factors may be involved. The insects you introduced may not suited for the climate of your home. Furthermore, there are other predators present in the vicinity that can devour the beneficial insects.
