The adult emerges from the pupa inside the leaf mine. The fully grown larva is about 2 mm long. D. isaea, being shipped as adults, offer the benefit of fast oviposition or egg-laying.These tiny wasps parasitize leafminer larvae in the first and second stages of development. The potential of commonly used sticky traps (yellow, blue and transparent) to attract the two major natural enemies of the leaf miners, Dacnusa sibirica Telenga (Hymenoptera: Braconidae) and . Diglyphus isaea is a beneficial parasitic wasp attacks leafminer larvae, killing them before they can reproduce. They can, therefore, overwhelm the pests in a matter of time with few, if any, other considerations. Host plant species can affect the behavior and attributes of parasitoids, such as host searching, oviposition, and offspring fitness. Parasitic Hymenoptera bred from the family Agromyzidae (Diptera) with special reference to south Florida.

Diglyphus isaea is an ectoparasitic wasp that parasitizes leaf miner larvae in field and greenhouse crops. Adult females will also feed on host larvae as a source of protein in order to produce more eggs (usually the smaller host larvae that are not large enough to support its eggs). Lasalle and Parrella (1991) indicated that Diglyphis begini also parasitizes Liriomyza trifolii, Liriomyza huidobrensis and Liriomyza bryoniae in North America.

Tetrastichinac). Egg: The adult female Diglyphus parasitoid stings the dipteran host larva to paralyze it. The larvae were removed from the mine of a bean leaf. They can feed on over 200 larvae in their lifetime. The eggs develop into parasitic wasps inside the mine (but outside the leaf miner), using the dead larvae as food. The stinging conveys a paralyzing toxin to the pests. It is in both the North and South islands of New Zealand. The larvae were removed from the mine of a bean leaf.
