When the larva hatches, it punctures the leaf miner and sucks out its body fluids. While destructive leaf miners often survive pesticide treatments because they are protected inside the tunnels, they cannot escape the parasite, which raps its antennae on the mine to locate the miner. They can feed on over 200 larvae in their lifetime. But these are optimum conditions, and not necessarily a prerequisite of successful implementation.

Knowing and recognizing: The biology of glasshouse pests and their natural enemies. When the larva hatches, it punctures the leaf miner and sucks out its body fluids. This makes this parasitoid an effective biological control agent in greenhouse crops in the Northern Hemisphere. It can parasitize many species of leaf miner. Approximately 1 diglyphus should be released per 10 sq. Kaspi and Parrella (2005) reported that the insecticide Abamectin has little impact on Diglyphis isaea adults or the larvae within the leaf mines of chrysanthemums.
