The larvae of this tiny, long-legged fly feed on more than 60 species of aphids by paralyzing their prey with toxic saliva. Pollen plants will bring aphid midges to your garden.

The adult female of the species injects its eggs into host insects. The larvae then feed inside their hosts, which include moth and beetle larvae and aphids. The host dies once the larvae have completed development. Grow nectar plants with small flowers, such as dill, parsley, wild carrot, and yarrow, to bring them to your garden.
Damsel bugs feed on aphids, small caterpillars, leafhoppers, thrips, and other pesky pests. Collect damsel bugs from alfalfa fields, using a sweep net, and then release them around your site.
