Habrobracon hebetor is a minute wasp of the family Braconidae that is an ectoparasitoid of several species of moth caterpillars.

[7] At 30 °C (86 °F), the life cycle of the wasp is about ten to thirteen days from initial parasitism to final emergence of the adult.

One to 8 eggs are deposited in individual, paralyzed, late instar moth larvae.

[citation needed] Habrobracon hebetor is remarkably resistant to radiation.

In this study, irradiated groups even had an increased life span compared to non-irradiated control groups, an effect attributed to the lack of activity of irradiated individuals.
