none The female parasite B. hebetor is not able to distinguish the host that she or other females of its species attacked. Thus, a host larva of Galleria mellonella bearing numerous eggs of this parasite most probably was superparasitized. This phenomenon induces obvious decreases in the length of the parasite developmental period and its progeny and increases the rate of mortality in immature stages and number of males in the progeny. Individuals parasitizing the host earlier are always survivors and those attacking it later are losers. Losers are either devoured early by the older larvae or die later under the state of starvation when the host individual provides insufficient supply of food for all attacking larvae.
